Network Designing
Year / Semester: 
4th Semester

To understand Network design and different layers in the network protocol.


Review of Basic Concepts

• Network Architecture – Protocol Hierarchies, Layered model, services, interface • Reference Models • Underlying Technologies LAN’s (Ethernet, Token Ring, Wireless) , Point-to-Point WAN’s , Switched WAN’s (X.25, Frame Relay, ATM), Connecting devices , Addressing (Physical, Network, Transport)

The Internet Layer Protocols

• IP- Datagram, fragmentation and reassembly, • ICMP- types of messages, error reporting, ICMP Package

Bootstrap and Autoconfiguration


Routing Protocols

• Interior and Exterior Routing – RIP, OSPF, BGP • Multicast Routing- Unicast , Multicast and Broadcast, Multicasting, Multicast trees,

The Transport Layer

• The transport Service- Services provided, Service primitives, Sockets • Process-to-Process Communication – Port addrresses • Elements of transport protocols – addressing, connection establishment, connection release, flow control and buffering, multiplexing, crash recovery • UDP – Introduction, Remote Procedure Call, • TCP – Service model, Protocol, frame format, connection establishment, release, connection management, Silly Window Syndrome-Nagle’s algorithm, error control, congestion control, state transition diagram

Sockets and Client-Server Model

Client-Server Model – Concurrency, Processes, Socket Interface – Sockets, Byte Ordering, Socket System Calls, Connectionless and Connection Oriented applications Implementation of Sockets ( C/Java etc)

The Application Layer

DNS, Telnet and Rlogin, FTP, TFTP, SNMP, SMTP, World Wide Web( Client and Server Side, cookies, wireless web), Java and the Internet, Multimedia (streaming audio, Internet Radio, voice over IP - RTP , video standards), Real time traffic over the internet

Mobile IP

Mobility, routing and addressing, characteristics, operation, foreign agent discovery , registration and communication, two crossing problem, communication with computers on the home front. Few examples of Network Design
