3 About Me Rakhmadhany Primananda, S.T., M.Kom Research and Interest:
Lab. Jaringan Komputer HP: FB: /rakhmadhany.primananda Research and Interest: Wireless Network Linux Sysadmin Multimedia Networking Network Security

4 Course Goal Mengetahui terminologi dasar komponen pembentuk arsitektur jaringan komputer Mengerti tentang arsitektur OSI, TCP/IP, dan Internet

5 Grading Tugas dan Quiz : 30% UTS : 30% UAS/Project : 40% Keaktifan ++

6 Application Most people know about the Internet through network application WWW Instant Messaging Social Media 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

21 Protocol Layering and Routing
Host A Host B Application Layer Application Layer HTTP Message Transport Layer Transport Layer TCP Packet Router Internet Layer Internet Layer Internet Layer IP Datagram IP Datagram Network Layer Network Layer Network Layer Ethernet Frame Ethernet Frame Physical Network Physical Network
