Streaming Multimedia
File Sharing
etc..

7. Requirement of Computer Network
Support for common services
Cost effective resource sharing
Connectivity
Reliability

8. Connectivity Understanding with this terminologies: Scale Link Nodes
Point to point
Multiple Access
Switched Network (Circuit vs Packet)
Packet vs Message
Store and Forward

9. Connectivity (cont.) Terminologies: A switched network
Cloud
Hosts
Switches
Internetwork
Router/Gateway
Host to Host Connectivity
Address
Routing
Unicast, broadcast, multicast
A switched network
Interconnection of network

10. Cost Effective Resource Sharing
Resource: link and node
How to share a link?
Multiplexing
Demultiplexing
Synchrounous Time division
multiplexing
Multiplexing multiple logical flows over a single physical link

11. Cost Effective Resource Sharing (cont.)
FDM: Frequency Division Multiplexing
Statistical Multiplexing
Data transmitted based on demand of each flow
Packet vs Messages
FIFO, Round robin, Priorities (QoS)
Statistical multiplexing: a switch multiplexing packets from multiple sources onto one shared link

12. Architecture, topology, protocol
What is a computer network architecture?
What is a computer network topology?
What is a computer network protocol?
???

13. Architecture, topology, protocol (cont.)
Network architecture - the design of communication network, on how data flows in a network
Network topology - the study of the arrangement or mapping of the elements (links, nodes,etc.) of a network
Network protocol - a common set of rules and signals that governs the communication between computers on a network

14. Network Architecture
Example of a layered network system

15. Network Architecture (cont.)
Layered system with alternative abstractions available at given layer

16. OSI Architecture

17. Description of Layers Physical Layer
Handles the transmission of raw bits over a communication link
Data Link Layer
Collects a stream of bits into a larger aggregate called a frame
Network adaptor along with device driver in OS implement the protocol in this layer
Frames are actually delivered to hosts
Network Layer
Handles routing among nodes within a packet-switched network
Unit of data exchanged between nodes in this layer is called a packet
The lower three layers are implemented on all network nodes

18. Description of Layers (cont.)
Transport Layer
Implements a process-to-process channel
Unit of data exchanges in this layer is called a message
Session Layer
Provides a name space that is used to tie together the potentially different transport streams that are part of a single application
Presentation Layer
Concerned about the format of data exchanged between peers
Application Layer
Standardize common type of exchanges
The transport layer and the higher layers typically run only on end-hosts and not on the intermediate switches and routers

19. Internet Architecture
Alternative view of the
Internet architecture. The
“Network” layer shown here
is sometimes referred to as
the “sub-network” or “link”
layer.
Internet Protocol Graph

20. Protocol Protocol in each layer have
Service interface with upper / lower layer
Peer to peer interface with host on same layer
