Internet Protocol Datagram construction
Each datagram has two components: a header and a payload. The IP header is tagged with the source IP address, the destination IP address, and other meta-data needed to route and deliver the datagram. The payload is the data that is transported. This method of nesting the data payload in a packet with a header is called encapsulation.
3
Datagram Congestion Control Protocol
The Datagram Congestion Control Protocol (DCCP) is a message-oriented transport layer protocol
4
Datagram Congestion Control Protocol
DCCP provides a way to gain access to congestion control mechanisms without having to implement them at the application layer. It allows for flow-based semantics like in Transmission Control Protocol (TCP), but does not provide reliable in-order delivery. Sequenced delivery within multiple streams as in the Stream Control Transmission Protocol (SCTP) is not available in DCCP.
5
Datagram Congestion Control Protocol
Currently such applications have often either settled for TCP or used User Datagram Protocol (UDP) and implemented their own congestion control mechanisms, or have no congestion control at all.
6
Datagram Congestion Control Protocol
While being useful for these applications, DCCP can also be positioned as a general congestion control mechanism for UDP-based applications, by adding, as needed, a mechanism for reliable and/or in-order delivery on the top of UDP/DCCP. In this context, DCCP allows the use of different, but generally TCP-friendly congestion control mechanisms.
7
Datagram Congestion Control Protocol
A DCCP connection contains acknowledgment traffic as well as data traffic. Acknowledgments inform a sender whether its packets have arrived, and whether they were marked by Explicit Congestion Notification (ECN). Acknowledgements are transmitted as reliably as the congestion control mechanism in use requires, possibly completely reliably.
8
Datagram Congestion Control Protocol
DCCP has the option for very long (48-bit) sequence numbers corresponding to a packet ID, rather than a byte ID as in TCP. The long length of the sequence numbers is intended to guard against "some blind attacks, such as the injection of DCCP-Resets into the connection."
9
Datagram Congestion Control Protocol DCCP implementations
As of June 2008, at least two DCCP implementations are actively maintained. The Linux kernel implementation was first available in Linux release The dccp-tp implementation is optimized for portability, but has had no changes since June 2008.
10
Datagram Congestion Control Protocol DCCP implementations
Recently, a new user-space implementation of DCCP has been under way. The purpose of this implementation is to provide a standardized, portable NAT-friendly framework for peer-to-peer communications with flexible congestion control, depending on application.
11
Datagram A datagram is a basic transfer unit associated with a packet-switched network in which the delivery, arrival time, and order of arrival are not guaranteed by the network service.
12
Datagram Origin of the term
The term datagram appeared first within the project CYCLADES, a packet switching network created in the early 1970s, and was coined by Louis Pouzin by combining the words data and telegram. CYCLADES was the first network to make the hosts responsible for the reliable delivery of data, rather than the network itself, using unreliable datagrams and associated end-to-end protocol mechanisms.
13
Datagram Origin of the term
“The inspiration for datagrams had two sources. One was Donald Davies' studies. He had done some simulation of datagram networks, although he had not built any, and it looked technically viable. The second inspiration was I like things simple. I didn't see any real technical motivation to overlay two levels of end-to-end protocols. I thought one was enough.”
14
Datagram Definition A datagram or packet needs to be self-contained without reliance on earlier exchanges because there is no connection of fixed duration between the two communicating points as there is, for example, in most voice telephone conversations.
15
Datagram is opposite of Virtual circuit.[page needed]
Datagram Definition Datagram is opposite of Virtual circuit.[page needed]
16
Datagram Definition “A self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer and the transporting network.”
17
Datagram Definition Datagram service is often compared to a mail delivery service, the user only provides the destination address, but receives no guarantee of delivery, and no confirmation upon successful delivery.
18
Datagram Definition Datagram service routes datagrams without first creating a predetermined path. There is also no consideration given to the order in which it and other datagrams are sent or received. In fact, many datagrams in the same group can travel along different paths before reaching the same destination.
19
Datagram Structure of a datagram
Each datagram has two components, a header and a data payload. The header contains all the information sufficient for routing from the originating equipment to the destination without relying on prior exchanges between the equipment and the network. Headers may include source and destination addresses as well as a type field. The payload is the data to be transported. This process of nesting data payloads in a tagged header is called encapsulation.
20
Datagram Use in the Internet Protocol
Datagram service is a service provided by IP at the Internet layer. It is a connectionless, best effort, unreliable, message delivery service. Many higher level protocols including TCP (a connection-oriented service) depend on IP's Datagram service, laying additional functionality on top. UDP uses IP's Datagram service as well.
21
Datagram Use in the Internet Protocol
The term datagram is often considered synonymous to packet but there are some nuances. The term datagram is generally reserved for packets of an unreliable service that does not notify the user if delivery fails, while the term packet applies to any message formatted as a packet. For example, Internet Protocol (IP) provides an unreliable service and UDP over IP is also unreliable. That is why IP and UDP packets are generally called datagrams.
22
Datagram Use in the Internet Protocol
If a datagram fragments, then its fragments may be referred to as packets, but not as datagrams. TCP refers to its fragments as TCP segments, not packets, presumably to distinguish them from unreliable fragments.
23
Circuit switching Compared to datagram packet switching
Circuit switching contrasts with packet switching which divides the data to be transmitted into small units, called packets, transmitted through the network independently. Packet switching shares available network bandwidth between multiple communication sessions.
24
Circuit switching Compared to datagram packet switching
Multiplexing multiple telecommunications connections over the same physical conductor has been possible for a long time, but nonetheless each channel on the multiplexed link was either dedicated to one call at a time, or it was idle between calls.
25
Circuit switching Compared to datagram packet switching
In circuit switching, and virtual circuit switching, a route and bandwidth is reserved from source to destination. Circuit switching can be relatively inefficient because capacity is guaranteed on connections which are set up but are not in continuous use, but rather momentarily. However, the connection is immediately available while established.
26
Circuit switching Compared to datagram packet switching
Datagram packet switching networks do not require a circuit to be established and allow many pairs of nodes to communicate concurrently over the same channel.
27
AppleTalk - Datagram Delivery Protocol
DDP was the lowest-level data-link-independent transport protocol. It provided a datagram service with no guarantees of delivery. All application-level protocols, including the infrastructure protocols NBP, RTMP and ZIP, were built on top of DDP. AppleTalk's DDP corresponds closely to the Network layer of the Open Systems Interconnection (OSI) communication model.

37
NetBIOS - Datagram distribution service
Datagram mode is connectionless; the application is responsible for error detection and recovery. In NBT, the datagram service runs on UDP port 138.
38
Datagram Delivery Protocol
Datagram Delivery Protocol (DDP) is a member of the AppleTalk networking protocol suite. Its main responsibility is for socket-to-socket delivery of datagrams over an AppleTalk network.
39
Datagram Delivery Protocol
Note: All application-level protocols, including the infrastructure protocols NBP, RTMP and ZIP were built on top of DDP.
40
Ethernet - Layer 2 – Datagrams
In IEEE datagrams are called "frames". A frame begins with preamble and start frame delimiter, followed by an Ethernet header featuring source and destination MAC addresses. The middle section of the frame consists of payload data including any headers for other protocols (e.g., Internet Protocol) carried in the frame. The frame ends with a 32-bit cyclic redundancy check, which is used to detect corruption of data in transit.

46
IEEE 802.11 - Layer 2 – Datagrams
The datagrams are called "frames". Current standards define "frame" types for use in transmission of data as well as management and control of wireless links.
47
IEEE 802.11 - Layer 2 – Datagrams
Frames are divided into very specific and standardized sections. Each frame consists of a MAC header, payload and frame check sequence (FCS). Some frames may not have the payload. The first two bytes of the MAC header form a frame control field specifying the form and function of the frame. The frame control field is further subdivided into the following sub-fields:
48
IEEE 802.11 - Layer 2 – Datagrams
Protocol Version: two bits representing the protocol version. Currently used protocol version is zero. Other values are reserved for future use.
49
IEEE 802.11 - Layer 2 – Datagrams
Type: two bits identifying the type of WLAN frame. Control, Data and Management are various frame types defined in IEEE
50
IEEE 802.11 - Layer 2 – Datagrams
Sub Type: Four bits providing additional discrimination between frames. Type and Sub type together to identify the exact frame.
51
IEEE 802.11 - Layer 2 – Datagrams
ToDS and FromDS: Each is one bit in size. They indicate whether a data frame is headed for a distribution system. Control and management frames set these values to zero. All the data frames will have one of these bits set. However communication within an IBSS network always set these bits to zero.
52
IEEE 802.11 - Layer 2 – Datagrams
More Fragments: The More Fragments bit is set when a packet is divided into multiple frames for transmission. Every frame except the last frame of a packet will have this bit set.
53
IEEE 802.11 - Layer 2 – Datagrams
Retry: Sometimes frames require retransmission, and for this there is a Retry bit which is set to one when a frame is resent. This aids in the elimination of duplicate frames.
54
IEEE 802.11 - Layer 2 – Datagrams
Power Management: This bit indicates the power management state of the sender after the completion of a frame exchange. Access points are required to manage the connection and will never set the power saver bit.
55
IEEE 802.11 - Layer 2 – Datagrams
More Data: The More Data bit is used to buffer frames received in a distributed system. The access point uses this bit to facilitate stations in power saver mode. It indicates that at least one frame is available and addresses all stations connected.
56
IEEE 802.11 - Layer 2 – Datagrams
Order: This bit is only set when the "strict ordering" delivery method is employed. Frames and fragments are not always sent in order as it causes a transmission performance penalty.
57
IEEE 802.11 - Layer 2 – Datagrams
The next two bytes are reserved for the Duration ID field. This field can take one of three forms: Duration, Contention-Free Period (CFP), and Association ID (AID).
58
IEEE 802.11 - Layer 2 – Datagrams
An frame can have up to four address fields. Each field can carry a MAC address. Address 1 is the receiver, Address 2 is the transmitter, Address 3 is used for filtering purposes by the receiver.
59
IEEE 802.11 - Layer 2 – Datagrams
The Sequence Control field is a two-byte section used for identifying message order as well as eliminating duplicate frames. The first 4 bits are used for the fragmentation number and the last 12 bits are the sequence number.
60
IEEE 802.11 - Layer 2 – Datagrams
An optional two-byte Quality of Service control field which was added with e.
61
IEEE 802.11 - Layer 2 – Datagrams
The Frame Body field is variable in size, from 0 to 2304 bytes plus any overhead from security encapsulation and contains information from higher layers.
62
IEEE 802.11 - Layer 2 – Datagrams
The Frame Check Sequence (FCS) is the last four bytes in the standard frame. Often referred to as the Cyclic Redundancy Check (CRC), it allows for integrity check of retrieved frames. As frames are about to be sent the FCS is calculated and appended. When a station receives a frame it can calculate the FCS of the frame and compare it to the one received. If they match, it is assumed that the frame was not distorted during transmission.
63
NetBIOS Frames protocol - Datagram distribution service
Datagram mode is "connectionless". A datagram is sent with a "Datagram" packet if it is being sent to a particular NetBIOS/NetBEUI name, or a "Datagram Broadcast" packet if it is being sent to all NetBIOS/NetBEUI names on the network.
64
Asynchronous Transfer Mode - Layer 2 – Datagrams
In the ISO-OSI reference model data link layer (layer 2), the basic transfer units, datagrams, are generically called frames. In ATM these frames are of a fixed (53 octets or bytes) length and specifically called "cells".
65
User Datagram Protocol
The User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite (the set of network protocols used for the Internet). With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without prior communications to set up special transmission channels or data paths. The protocol was designed by David P. Reed in 1980 and formally defined in RFC 768.
66
User Datagram Protocol
UDP uses a simple transmission model with a minimum of protocol mechanism. It has no handshaking dialogues, and thus exposes any unreliability of the underlying network protocol to the user's program. As this is normally IP over unreliable media, there is no guarantee of delivery, ordering or duplicate protection. UDP provides checksums for data integrity, and port numbers for addressing different functions at the source and destination of the datagram.
67
User Datagram Protocol
UDP is suitable for purposes where error checking and correction is either not necessary or performed in the application, avoiding the overhead of such processing at the network interface level
68
User Datagram Protocol
A number of UDP's attributes make it especially suited for certain applications.
69
User Datagram Protocol
It is transaction-oriented, suitable for simple query-response protocols such as the Domain Name System or the Network Time Protocol.
70
User Datagram Protocol
It provides datagrams, suitable for modeling other protocols such as in IP tunneling or Remote Procedure Call and the Network File System.
71
User Datagram Protocol
It is simple, suitable for bootstrapping or other purposes without a full protocol stack, such as the DHCP and Trivial File Transfer Protocol.
72
User Datagram Protocol
It is stateless, suitable for very large numbers of clients, such as in streaming media applications for example IPTV
73
User Datagram Protocol
The lack of retransmission delays makes it suitable for real-time applications such as Voice over IP, online games, and many protocols built on top of the Real Time Streaming Protocol.
74
User Datagram Protocol
Works well in unidirectional communication, suitable for broadcast information such as in many kinds of service discovery and shared information such as broadcast time or Routing Information Protocol
75
User Datagram Protocol - Service ports
Applications use datagram sockets to establish host-to-host communications. An application binds a socket to its endpoint of data transmission, which is a combination of an IP address and a service port. A port is a software structure that is identified by the port number, a 16 bit integer value, allowing for port numbers between 0 and Port 0 is reserved, but is a permissible source port value if the sending process does not expect messages in response.
76
User Datagram Protocol - Service ports
The Internet Assigned Numbers Authority has divided port numbers into three ranges
77
User Datagram Protocol - Packet structure
UDP is a minimal message-oriented Transport Layer protocol that is documented in IETF RFC 768.
78
User Datagram Protocol - Packet structure
UDP provides no guarantees to the upper layer protocol for message delivery and the UDP protocol layer retains no state of UDP messages once sent. For this reason, UDP is sometimes referred to as Unreliable Datagram Protocol.
79
User Datagram Protocol - Packet structure
UDP provides application multiplexing (via port numbers) and integrity verification (via checksum) of the header and payload. If transmission reliability is desired, it must be implemented in the user's application.
80
User Datagram Protocol - Packet structure
0 0 Source port Destination port
81
User Datagram Protocol - Packet structure
The UDP header consists of 4 fields, each of which is 2 bytes (16 bits). The use of the fields "Checksum" and "Source port" is optional in IPv4 (pink background in table). In IPv6 only the source port is optional .
82
User Datagram Protocol - Packet structure
This field identifies the sender's port when meaningful and should be assumed to be the port to reply to if needed. If not used, then it should be zero. If the source host is the client, the port number is likely to be an ephemeral port number. If the source host is the server, the port number is likely to be a well-known port number.
83
User Datagram Protocol - Packet structure
This field identifies the receiver's port and is required. Similar to source port number, if the client is the destination host then the port number will likely be an ephemeral port number and if the destination host is the server then the port number will likely be a well-known port number.
84
User Datagram Protocol - Packet structure
A field that specifies the length in bytes of the UDP header and UDP data. The minimum length is 8 bytes since that's the length of the header. The field size sets a theoretical limit of 65,535 bytes (8 byte header + 65,527 bytes of data) for a UDP datagram. The practical limit for the data length which is imposed by the underlying IPv4 protocol is 65,507 bytes (65,535 − 8 byte UDP header − 20 byte IP header).
85
User Datagram Protocol - Packet structure
In IPv6 Jumbograms it is possible to have UDP packets of size greater than 65,535 bytes. RFC 2675 specifies that the length field is set to zero if the length of the UDP header plus UDP data is greater than 65,535.
86
User Datagram Protocol - Packet structure
The checksum field is used for error-checking of the header and data. If no checksum is generated by the transmitter, the field uses the value all-zeros. This field is not optional for IPv6.
87
User Datagram Protocol - Checksum computation
Checksum is the 16-bit one's complement of the one's complement sum of a pseudo header of information from the IP header, the UDP header, and the data, padded with zero octets at the end (if necessary) to make a multiple of two octets.
88
User Datagram Protocol - Checksum computation
In other words, all 16-bit words are summed using one's complement arithmetic. The sum is then one's complemented to yield the value of the UDP checksum field.
89
User Datagram Protocol - Checksum computation
If the checksum calculation results in the value zero (all 16 bits 0) it should be sent as the one's complement (all 1s).
90
User Datagram Protocol - Checksum computation
The difference between IPv4 and IPv6 is in the data used to compute the checksum.
91
User Datagram Protocol - IPv4 Pseudo Header
When UDP runs over IPv4, the checksum is computed using a "pseudo header" that contains some of the same information from the real IPv4 header. The pseudo header is not the real IPv4 header used to send an IP packet, it is used only for the checksum calculation.
92
User Datagram Protocol - IPv4 Pseudo Header
96 Source Port Destination Port
93
User Datagram Protocol - IPv4 Pseudo Header
The source and destination addresses are those in the IPv4 header. The protocol is that for UDP (see List of IP protocol numbers): 17 (0x11). The UDP length field is the length of the UDP header and data.
94
User Datagram Protocol - IPv4 Pseudo Header
UDP checksum computation is optional for IPv4. If a checksum is not used it should be set to the value zero.
95
User Datagram Protocol - IPv6 Pseudo Header
When UDP runs over IPv6, the checksum is mandatory. The method used to compute it is changed as documented in RFC 2460:
96
User Datagram Protocol - IPv6 Pseudo Header
Any transport or other upper-layer protocol that includes the addresses from the IP header in its checksum computation must be modified for use over IPv6 to include the 128-bit IPv6 addresses.
97
User Datagram Protocol - IPv6 Pseudo Header
When computing the checksum, again a pseudo header is used that mimics the real IPv6 header:
98
User Datagram Protocol - IPv6 Pseudo Header
Source Port Destination Port
99
User Datagram Protocol - IPv6 Pseudo Header
The source address is the one in the IPv6 header
100
User Datagram Protocol - Reliability and congestion control solutions
Lacking reliability, UDP applications must generally be willing to accept some loss, errors or duplication. Some applications such as TFTP may add rudimentary reliability mechanisms into the application layer as needed.
101
User Datagram Protocol - Reliability and congestion control solutions
Most often, UDP applications do not employ reliability mechanisms and may even be hindered by them. Streaming media, real-time multiplayer games and voice over IP (VoIP) are examples of applications that often use UDP. In these particular applications, loss of packets is not usually a fatal problem. If an application requires a high degree of reliability, a protocol such as the Transmission Control Protocol may be used instead.
102
User Datagram Protocol - Reliability and congestion control solutions
The Datagram Congestion Control Protocol (DCCP) is being designed as a partial solution to this potential problem by adding end host TCP-friendly congestion control behavior to high-rate UDP streams such as streaming media.
103
User Datagram Protocol - Applications
Numerous key Internet applications use UDP, including: the Domain Name System (DNS), where queries must be fast and only consist of a single request followed by a single reply packet, the Simple Network Management Protocol (SNMP), the Routing Information Protocol (RIP) and the Dynamic Host Configuration Protocol (DHCP).
104
User Datagram Protocol - Applications
Voice and video traffic is generally transmitted using UDP
105
User Datagram Protocol - Comparison of UDP and TCP
Transmission Control Protocol is a connection-oriented protocol, which means that it requires handshaking to set up end-to-end communications. Once a connection is set up user data may be sent bi-directionally over the connection.
106
User Datagram Protocol - Comparison of UDP and TCP
Reliable – TCP manages message acknowledgment, retransmission and timeout. Multiple attempts to deliver the message are made. If it gets lost along the way, the server will re-request the lost part. In TCP, there's either no missing data, or, in case of multiple timeouts, the connection is dropped.
107
User Datagram Protocol - Comparison of UDP and TCP
Ordered – if two messages are sent over a connection in sequence, the first message will reach the receiving application first. When data segments arrive in the wrong order, TCP buffers delay the out-of-order data until all data can be properly re-ordered and delivered to the application.
108
User Datagram Protocol - Comparison of UDP and TCP
Heavyweight – TCP requires three packets to set up a socket connection, before any user data can be sent. TCP handles reliability and congestion control.
109
User Datagram Protocol - Comparison of UDP and TCP
Streaming – Data is read as a byte stream, no distinguishing indications are transmitted to signal message (segment) boundaries.
110
User Datagram Protocol - Comparison of UDP and TCP
UDP is a simpler message-based connectionless protocol
111
User Datagram Protocol - Comparison of UDP and TCP
Unreliable – When a message is sent, it cannot be known if it will reach its destination; it could get lost along the way. There is no concept of acknowledgment, retransmission, or timeout.
112
User Datagram Protocol - Comparison of UDP and TCP
Datagrams – Packets are sent individually and are checked for integrity only if they arrive. Packets have definite boundaries which are honored upon receipt, meaning a read operation at the receiver socket will yield an entire message as it was originally sent.
113
User Datagram Protocol - Comparison of UDP and TCP
No congestion control – UDP itself does not avoid congestion, and it's possible for high bandwidth applications to trigger congestion collapse, unless they implement congestion control measures at the application level.
114
IP fragmentation attacks - IP fragment too many datagrams
The Too Many Datagrams exploit is identified by an excessive number of incomplete fragmented datagrams detected on the network. This is usually either a denial of service attack or an attempt to bypass security measures. An example of "Too Many Datagrams", "Incomplete Datagram" and "Fragment Too Small" is the Rose Attack.
115
IP fragmentation attacks - IP fragment incomplete datagram
This exploit occurs when a datagram can not be fully reassembled due to missing data. This can indicate a denial of service attack or an attempt to defeat packet filter security policies.
116

Very Simple Control Protocol - VSCP event datagram structure
Events that are broadcast contain a number of fields together forming one VSCP datagram. Exactly how these fields are mapped onto the physical layer is specified for a number of physical layer protocols such as CAN, Ethernet, TCP, For others it is not yet
134
Very Simple Control Protocol - VSCP event datagram structure
defined but it is in general not difficult to map these fields onto a physical layer protocol. There are 2 levels of the VSCP protocol called LEVEL I LEVEL II. They are both basically the same protocol but differ in size of the different fields.
135
Very Simple Control Protocol - VSCP event datagram structure
Level I is intended to run on nodes with more constrained resources and fields are defined a bit more conservative. Level I is in fact a subset of level II and with an appropriate gateway events can transverse between a Level I II network.
136
Very Simple Control Protocol - VSCP event datagram structure
Level II is intended to be run on nodes that have little resource constraints and can easily cope with larger message sizes.

The catagen phase is a short transition stage that occurs at the end of the anagen phase. It signals the end of the active growth of a hair. This phase lasts for about 2–3 weeks while the hair converts to a club hair.
138
Hair follicle - Catagen phase
A club hair is formed during the catagen phase when the part of the hair follicle in contact with the lower portion of the hair becomes attached to the hair shaft. This process cuts the hair off from its blood supply and from the cells that produce new hair. When a club hair is completely formed, about a 2 week process, the hair follicle enters the telogen phase.

Buddhist philosophy - Tathagatagarbha
The Tathagatagarbha|tathāgathagarbha sutras, in a departure from mainstream Buddhist language, insist that the potential for awakening is inherent to every sentient being. They marked a shift from a largely apophatic (negative) philosophical trend within Buddhism to a decidedly more cataphatic (positive) modus.
148
Buddhist philosophy - Tathagatagarbha
Prior to the period of these scriptures, Mahāyāna metaphysics had been dominated by teachings on emptiness in the form of Madhyamaka philosophy. The language used by this approach is primarily negative, and the tathāgatagarbha genre of sutras can be seen as an attempt to state orthodox Buddhist teachings of dependent origination using positive language instead, to prevent people from being turned away from Buddhism by a false impression of nihilism.
149
Buddhist philosophy - Tathagatagarbha
In these sutras the perfection of the wisdom of not-self is stated to be the true self; the ultimate goal of the path is then characterized using a range of positive language that had been used previously in Indian philosophy by essentialist philosophers, but which was now transmuted into a new Buddhist vocabulary to describe a being who has successfully completed the Buddhist path.Sallie B

Buddhist philosophy - Tathagatagarbha
The word self (atman) is used in a way idiosyncratic to these sutras; the true self is described as the perfection of the wisdom of anatta|not-self in the Buddha-Nature Treatise, for example. Language that had previously been used by essentialist non-Buddhist philosophers was now adopted, with new definitions, by Buddhists to promote orthodox teachings.

This may be so, still they were not unknown. Some men sed to join enemy force. In battle they desert enemy line and attack them. Ambush was not an uncommon stratagem. Matchlockmen were hidden in high crops, or on the edge of a ravine, at a spot where the opposite leaders would most probably pass. At the proper moment a volley would be discharged, and occasionally with deadly effect. An ambush was not infrequently supplemented by pretended flight, so arranged as

God in Buddhism - Tathagatagarbha, Dharmakaya and God
Mahayana Buddhism, unlike Theravada Buddhism|Theravada, talks of the mind using terms such as Tathagatagarbha|the womb of the Thus-come One (tathagatagarbha).

God in Buddhism - Tathagatagarbha, Dharmakaya and God
According to the Tathagatagarbha sutras, the Buddha taught the existence of this spiritual essence called the tathagatagarbha or Buddha-nature, which is present in all beings and phenomena. Dr. B. Alan Wallace writes of this doctrine:
181
God in Buddhism - Tathagatagarbha, Dharmakaya and God
Dr. Wallace further writes on how the primal Buddha, Samantabhadra, who in some scriptures is viewed as one with the tathagatagarbha, forms the very radiating foundation of both samsara and nirvana. Noting a progression within Buddhism from doctrines of a mind-stream (bhavanga) to that of the absolutised tathagatagarbha, Wallace comments that it may be too simple in the light of such doctrinal elements to define Buddhism unconditionally as non-theistic:

Thus, in such doctrines, a very positive goal is envisioned, which is said to lie beyond the grasp of the five senses and the ordinary, restless mind, and only attainable through direct meditative perception and when all inner pollutants (twisted modes of view, and all moral contaminants) are purged, and the inherently deathless, spotless, radiantly shining mind of Buddha stands revealed

Anatta - Tathagatagarbha Sutras
According to some scholars, the tathagatagarbha/Buddha nature discussed in these sutras does not represent a substantial self (atman); rather, it is a positive language and expression of sunyata (emptiness) and represents the potentiality to realize Buddhahood through Buddhist practices.Heng-Ching Shih,[ The Significance Of 'Tathagatagarbha' -- A Positive Expression Of 'Sunyata'] Other scholars do in fact detect leanings towards monism in these tathagatagarbha references.Jamie Hubbard, Absolute Delusion, Perfect Buddhahood, University of Hawai’i Press, Honolulu, 2001, pp

Patagonian toothfish - Ecology
As most toothfish fisheries are managed in accordance with CCAMLR regulations and conservation measures, it should be noted that CCAMLR adopts an “ecosystem approach” which requires that all other living resources of the Southern Ocean are treated as an integrated system where effects on predator, prey and related species are considered, and decisions on sustainable harvesting levels are made on the basis of sound, internationally peer reviewed scientific advice.

Commercial fishing of toothfish is managed by the Convention for the Conservation of Antarctic Marine Living Resources|Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) inside the CCAMLR Convention Area which spans the Antarctic continent and waters between 45°S and 60°S
233
Patagonian toothfish - Management
In the legal toothfish fisheries managed by CCAMLR and countries with territorial waters, the most common method is fishing by longlines (where a long mainline is set in the water, with many baited hooks coming off that line)
234

Patagonian toothfish - Management
In 2011 the CCAMLR Scientific Committee Chair, David Agnew, was quoted as saying “levels of seabird mortality are negligible in most areas”, with the one region yet to achieve these near zero results, having reduced seabird interactions by over 98% from their peak levels, and have continued to improve each year.
241
Patagonian toothfish - Management
Trawling generally catches toothfish in the smaller size range, which requires calculations to be made at the annual stock assessment meetings of CCAMLR to take these catches of smaller sized fish into account, and lowers the overall available catch of toothfish by trawl. CCAMLR has prohibited all trawl fishing in high seas waters and exploratory fisheries.
242
Patagonian toothfish - Compliance
To minimise the risk of long-term adverse effects on target species, by-catch species and marine ecosystems, CCAMLR uses a number of compliance systems to monitor fishing activities in the Convention Area. This includes:

Patagonian toothfish - Legal fishing
The total allowable catch of toothfish worldwide is around 24,800t in 2012/13, with 80% of this coming from COLTO members, and 50% of the total catch (12,422 tonnes) now being independently certified as coming from sustainable and well managed fisheries by the Marine Stewardship Council (with two other fisheries totalling 4,700 tonnes under full MSC assessment).
257
Patagonian toothfish - Legal fishing
It is estimated by CCAMLR that around 5% of the worldwide toothfish catch is taken by IUU operators, and that product does not have the current Catch Documentation System evidence trail associated with it, so cannot be sold legally into major markets including USA, EU, and Japan.
258
Patagonian toothfish - Illegal fishing
In the late 1990s to early 2000s, illegal, unreported and unregulated fishing (IUU) for toothfish nearly collapsed some fisheries in the Southern Ocean. Though, since 2005, thanks to CCAMLR Member nations, government patrol vessels, NGOs, media exposure and a trade and port state measures, IUU fishing has been all but eliminated from within countries' exclusive economic zones, though a relatively small portion of IUU fishing still occurs in high seas areas.
259
Patagonian toothfish - Illegal fishing
At the peak of IUU fishing, illegal catches were estimated to be 32,000 tonnes in 1997 with approximately 55 vessels believed to be active. By 2010, IUU catches had fallen to an estimated 1,615 tonnes, all taken in high seas areas, with just four IUU fishing vessels reported to be active. This is a decrease in IUU fishing by over 95% since the mid 1990s. CCAMLR estimates that 90% of IUU catches are now of Antarctic Toothfish, not Patagonian Toothfish.
260
Patagonian toothfish - Illegal fishing

* Only marine fisheries products validated as legal by the relevant flag state or exporting state can be imported to or exported from the EU.
266
Patagonian toothfish - Illegal fishing
* A European black list having been drawn up covering both IUU vessels and states that turn a blind eye to illegal fishing activities.
267

Human habitation of the region dates back thousands of years, with some early archaeological findings in the area dated to at least the 13th millennium BC, although later dates of around the 10th millennium BC are more securely recognized. There is evidence of human activity at Monte Verde in Llanquihue Province, Chile dated to around 12,500 BC. The glacial period ice-fields and subsequent large meltwater streams would have made settlement difficult at that time.

Patagonian giants The 'Patagones' or 'Patagonian giants' are a mythology|mythical race of people, who first began to appear in early European accounts of the then little-known region and coastline of Patagonia. They were supposed to have exceeded at least double normal human height, some accounts giving heights of or more. Tales of these improbable people would take a hold over European concepts of the region for some 250 years, until they were substantially debunked at the end of the 18th century.
411
Patagonian giants First mention of these people came from the voyage of Ferdinand Magellan and his crew, who claimed to have seen them while exploring the coastline of South America en route to their circumnavigation of the world in the 1520s. Antonio Pigafetta, one of the expedition's few survivors and the chronicler of Magellan's expedition, wrote in his account about their encounter with natives twice a normal person's height:

414
Patagonian giants In 1579, Sir Francis Drake's ship chaplain, Francis Fletcher (clergyman)|Francis Fletcher, wrote about meeting very tall Patagonians.
415
Patagonian giants Also in the 1590s, William Adams, an Englishman aboard a Dutch ship rounding Tierra del Fuego reported a violent encounter between his ship's crew and unnaturally tall natives.
416
Patagonian giants In 1766, a rumour leaked out upon their return to United Kingdom|Britain that the crew of HMS Dolphin (1751)|HMS Dolphin, captained by Commodore (rank)|Commodore John Byron, had seen a tribe of natives in Patagonia when they passed by there on their circumnavigation of the globe. However, when a newly edited revised account of the voyage came out in 1773, the Patagonians were recorded as being 6ft 6 in (1.98 m); very tall, but by no means giants.
417
Patagonian giants The people encountered by Byron were in all likelihood the Tehuelche people|Tehuelches, indigenous to the region. Later writers consider the Patagonian giants to have been a hoax, or at least an exaggeration and mis-telling of earlier European accounts of the region.

Patagonian sheep farming boom
Besides altering the demographic and economic outlook of Southern Patagonia the sheep farming boom did also changed the steppe ecosystem.
435
Patagonian sheep farming boom
Sheep farming in Patagonia was carried out in a estancia system. Each of these estancias was administered from a casco central (a central complex of buildings) where administrators, Ranch foreman|foremen and workers lived.
436
Patagonian sheep farming boom - Development
In 1843 Chile established a colony in Brunswick Peninsula to assert sovereignty over the strategic Strait of Magellan. Early sheep herding activity in the Chilean colony was very modest. The first men to realize the potential for large-scale sheep herding in the lands around the Strait of Magellan were a group of British immigrants that settled in Punta Arenas in the 1870s.
437

The first successful attempt at sheep farming in the Straits of Magellan is credited to the Englishman Henry Reynard () who raised sheep in 1877 on Isabel Island (Chile)|Isabel Island
438
Patagonian sheep farming boom - Ecological impact
The sheep farming boom did not only altered the demographic and economic outlook of Southern Patagonia but did also changed the steppe ecosystem. Research suggests that sheep excrement might have caused eutrophication of lagoons like Potrok Aike, and sheep might also had caused considerable erosion. The Strait of Magellan and the Atlantic coast were covered by natural grasslands so no deforestation|clearing of forests occurred during the introduction of sheep.

Patagonian Desert - Geography and climate
The Andes, to the desert's west, are the primary reason for the Patagonian desert status as they inhibit the westerly flow of moisture from the southern Pacific from reaching inland
469
Patagonian Desert - Geography and climate
Different climates can be distinguished: the coast north of the 45th parallel is much milder because of the warm currents from Brazil, and the entire northern half of the region is significantly warmer in the summer, when sunny weather predominates. Daily temperatures in the summer reach 31°C in the Rio Colorado region, a general 26°C to 29°C in the northern coast, and 24°C to 28°C in the northern plain, with nights around 12°C to 15°C in the coast and between 7°C and 10°C in the steppe.
470
Patagonian Desert - Geography and climate
In the south, summer temperatures decrease from 22°C to only 16°C along the coast, and from 24°C to 17°C along the steppes, while nights go from 8°C to 11°C on the coast, and from 6°C to 10°C in the steppe.
471
Patagonian Desert - Geography and climate
During the winter, the proximity to the coast and the altitude are the main factors: while northern coastal areas have mild winters, from 2°C at night to about 11°C during the day, southern Santa Cruz ranges from -2°C to 5°C, and Tierra del Fuego, from -3°C to 3°C, for a mean of 0°C.
472
Patagonian Desert - Geography and climate
Inland, the northern areas range from 0°C to 10°C in low areas, and from -5°C to 5°C on the plateaus (again, mean around 0°C), while in the south, low areas range from -3°C to 4°C, and higher areas are clearly below 0°C. The coldest spots usually register temperatures between -20°C and -25°C during cold waves, and the official record is -33.9°C in Chubut province. However, some towns claim to have had records of around -35°C.
473
Patagonian Desert - Geography and climate
Summer frost is common everywhere except for the northern coast, and even sleet and light snow can fall during the warm season. Winds are constant and very strong, from the west in most cases.

Patagonian mara - Status
The Patagonian mara is considered to be a near threatened species. Historically, maras have ranged from north-central Argentina south almost to Tierra del Fuego.Rood. J. P. (1972) Ecological and behavioral comparisons of three genera of Argentine cavies, Animal Behavior Monographs 5:1-83. Nevertheless, maras have been greatly affected by hunting and habitat alteration and have been extirpated in some areas including Buenos Aires Province. The mara skins have been used for bedspreads and rugs.

Climate of Argentina - Patagonia
The Patagonia is the most extensive region, with much colder weather accentuated in the southern part. The west is mostly constituted by a mountainous landscape scored by spectacular woods, lakes and glaciers; it has an arid plain in the centre, and long beaches with varied marine fauna to observe to the east. The south end of this region is the southernmost point in the world except for Antarctica.
512
Climate of Argentina - Patagonia
The Lake District on the eastern Andean slopes has at low altitudes, pleasant, dry summers between 20°C and 24°C, where temperatures over 30°C are very rare, and cold nights between 4°C and 8°C, with frost not uncommon. Winds blow constantly from the west and there can be long stretches of sunny weather; however, after cool changes, temperatures might stay around 10°C even in the middle of the summer, and low-altitude snow is not unprecedented.
513
Climate of Argentina - Patagonia
Fall is wet, with highs from 12°C to 15°C in April and 8°C to 11°C in May. Cold fronts can bring some early snowfall, and temperatures down to -8°C. Winter is also very rainy, but there is often sleet and snow as well, and large snowstorms with up to 30cm of snow can happen. Temperatures are usually between 3°C and 9°C during the day, and between -5°C and 3°C at night.
514
Climate of Argentina - Patagonia
With clear skies temperatures often fall below -10°C and they can reach -20°C (with highs in the -5°C to -2°C) during extreme winters. Long stretches of subzero temperatures are very rare, but intense frost is very common. Spring is mild and dry though with cold nights and frequent frosts. Snow persists in the mountains until mid-summer at 2,000 m, and never melts above 2,500 m.
515
Climate of Argentina - Patagonia
The central Patagonian plateau experiences marked contrasts: in the summer, temperatures climb to 28°C in the north and 22°C in the south, with extremes beyond 30°C; however, nights are cold with lows in the 5°C to 9°C range. Winters range between 2°C and 9°C during the day, and between -7°C and -3°C at night; however, when cold air masses move in from Antarctica, temperatures drop to incredibly low values. It is not uncommon to have large areas below -20°C, and some spots have reached -35°C.
516
Climate of Argentina - Patagonia
Precipitation on the Patagonian plateau is very low and uniformly distributed: annual averages are typically around with high variability.
517
Climate of Argentina - Patagonia
Extreme southerly areas in Tierra del Fuego are known for their storminess: in Ushuaia, at sea level, summer days average from 12°C to 16°C, and temperatures only reach 20°C a few times every year. Snow can happen anytime, but only becomes frequent in April; however, temperatures are not extreme in the winter because of the Ocean.
518
Climate of Argentina - Patagonia
The average days are about 0°C to 5°C, nights from -5°C to 0°C, and it is very rare to see nighttime temperatures fall below -12°C on the coast (but they fall to -20°C inland, with heavy snowcover) Snow can fall in large quantities some years. The ice fields in Santa Cruz have an extreme climate, with up to 4,000mm falling as snow, subzero temperatures, winds over 150 kilometers per hour and constant cloud cover.

Dainin Katagiri - Zen studies
During his years in San Francisco, Katagiri sometimes toyed with the idea of opening up his own Zen community nearby
521
Dainin Katagiri - USA During the 1970s and 1980s Katagiri sent over many of his Western students to train at Zuio-ji in Japan, where Narasaki Ikko roshi was abbot.Leighton, 28 In 1984, in the wake of the Zentatsu Richard Baker controversy resulting in Baker's resignation as abbot of San Francisco Zen Center, Katagiri came at the request of SFZC and served as abbot there on an interim basis until 1985 (returning to Minnesota afterward)
522
Dainin Katagiri - Personal life
Katagiri was married to Tomoe Katagiri, and the couple had two sons together (Yasuhiko and Ejyo). They married in 1960.
523
Dainin Katagiri - Acclaim
Soto priest and former student of Katagiri-Roshi, Zuiko Redding, has stated, My basic memory of Katagiri is of how he paid total attention to what was in front of him
524
Dainin Katagiri - Criticism
Following his death, it was rumored that Katagiri roshi had engaged in sexual relationships with some female students. These rumors have gained a higher profile since one of Katagiri's students, author Natalie Goldberg, wrote about her reaction to these claims.

Huangbo Xiyun - Tathāgatagarbha
Since all is Buddha-mind, all actions reflect the Buddha, are actions of a Buddha. Huángbò’s teaching on this reflected the Indian concept of the tathāgatagarbha, the idea that within all beings is the nature of the Buddha. Therefore, Huángbò taught that seeking the Buddha was futile as the Buddha resided within:

Huángbò was adamant that any form of “seeking” was not only useless, but obstructed clarity:

# embryonic tathāgata, the incipient Buddha, the cause of the Tathāgata,
531

# womb of the tathāgata, the fruit of Tathāgata.
532
Mahayana Mahaparinirvana Sutra - Tathagatagarbha
The Chinese translated the term tathāgata in its meaning as womb, c.q. fruit. It was translated as ru-lai-zag, tathagata (ru-lai) storehouse (zag). According to Mark Blum, Dharmaksema translates tathagatagarbha as rulai mizang or simply mizang, the tathagata's hidden treasury, mi meaning hidden, secret.

Touchatag On June 27, 2012 the Touchatag team has announced the shutdown of the project. inviting users to use [ IOTOPE] a similar open source Internet Of Things service which itself has no apparent activity since November 2012.
535
Touchatag - Service Application developers could use the correlation API to use the ACS functionalities to create contactless applications. For businesses, this ACS was extended with an RFID/NFC tag and reader catalogue, and applications like loyalty, interactive advertising and couponing.
536
Touchatag - Hardware The reader provided was an ACR122U Tag Reader, from Advanced Card Systems. The tags shipped with the reader were MiFare Ultralight tags.
537
Touchatag - Official clients
Touchatag hardware was supported by its makers on Microsoft Windows and Mac OS X platforms, and required registration on the website to work. An unsupported application was also available for Linux platforms. Like the Mac OS X application, the Linux application used PCSC-Lite for hardware access.
538
Touchatag - Unofficial clients
* [ TagEventor] (no apparent activity since 2011) is an open-source client from the [ Autelic] (dead link) association that works on Linux platforms, and does not use the web service from touchatag. It uses the PCSC-Lite daemon and can be run in foreground or daemon mode to make tag events available to user-space applications.
539
Touchatag - Programming libraries
* [ touchatag-processing] is a [ Processing] library from [ Augusto Esteves] that allows users to connect and read from multiple touchatag readers on the Windows platform. This library works with simply the reader's drivers, so there's no need to install any official or unofficial clients.

Dibatag The 'dibatag (Ammodorcas clarkei)', or Clarke's gazelle, is an antelope found in the sandy grasslands of Ethiopia and Somalia. Not a true gazelle, it is similarly marked, with a long, furry, black tail which is raised in flight. This gave rise to its name, which means erect tail in Somali language|Somali.
541
Dibatag The dibatag is listed by the IUCN as vulnerable to extinction due to hunting and human disturbance (including war). Only a few thousand individuals are left, with no captive population.

Cataglyphis - Description
The main source for the following is David Attenborough's book The Trials Of Life (1990), pp.120ff.The researcher in the field was Professor Rudiger Wehner of the University of Zurich. Many animals can create and hold a mental map of their territory in their heads. But how can this be done when there are no landmarks and the ground is constantly shifting?
546
Cataglyphis - Description
But this is when, for not much more than an hour, it’s safe for Cataglyphis to come out of their underground nests and forage
547
Cataglyphis - Description
On its outward journey, it zig-zags right and left. Every time it changes direction, it lifts its head and wheels around. It’s taken a bearing on the sun. In addition, it has to remember how far it went on each straight run. When it’s time to head for home, it has to sum all this data and come out with the precise direction needed. Some outward journeys take an ant a quarter of an hour, with sun-sightings every few seconds.
548
Cataglyphis - Description
Wehner followed individual ants using an apparatus which blocked direct sight of the sun whilst giving a false impression of where the sun was by using a mirror. When these ants headed for home, they dashed off to a point in the desert displaced by just the amount that the mirror had shifted the sun’s position.
549
Cataglyphis - Distribution
At least five different species of Cataglyphis occur in the Sahara desert, which may be considered the center of distribution for this genus.Bernard 1968 Some species reach into southern Russia, southern Spain,Mangan and Webb 2012 the European part of Turkey, the Aral-Caspian Sea|Caspian area near Tijanchan, Yugoslavia and Hungary.
