IMPORTANT INFORMATION
 
Students who are taking CS3103 must make it a habit to check IVLE regularly for Lecture notes, tutorials, assignments and announcements.  This website does not have any of the materials that are distributed via IVLE, and has only announcements and information about the module for the benefit of all those students who do not have access to IVLE prior to registering this module. 
 
The module CS3103 is now revamped and students must note the following important information.
  1. CS3103L (Computer Networks Laboratory) is co-requiiste for CS3103.
  2. CS3103 carries a weightage of 4 MC and CS3103L carries a weightage of 2 MC.
  3. Please note that for CS3103L,  there is no need to register separately. If your bid for CS3103 is successful, you would be  automatically registered for CS3103L.
  4. CS3103 is now comprised of  lectures, tutorials and maximum of 3 programming assignments.
  5. Since prerequisite for CS3103 is CS2105, it is assumed that students have all basic knowledge of networking. You may refer to materials in Week 0 to refresh your basic knowledge in Ethernet and TCP/IP.
  6. If you are an exchange student, you must have basic knowledge of computer networks like Local Area Networks, Ethernet, IP addressing, basic principles of IP forwarding and TCP.

 

Please note that the first lecture is on 16 August 2007 (Thursday) at 12 noon. Venue: C1/206
 

About the Module:

Academic Year: 

AY 2007/08, Semester 1

Module Description:

This module focuses mainly on TCP/IP protocol stack and discusses the design of various protocols in the stack, their semantics and interoperability issues including concepts behind in designing such protocols. The Internet technology protocols like ARP, ICMP, IP, DHCP, DNS, TCP, UDP, Routing protocols like RIP and OSPF, and new IP protocol version IPv6 are discussed in detail. The dynamics of the TCP protocol is discussed in detail including congestion control and its behaviour in the wireless and mobile network environment.  The client server communication paradigm is introduced and students are given the opportunity to develop distributed application using sockets and/or RPC-XML.

Module Objective:

  1. To enable students to understand network protocols and design principles, and  hold an intelligent and meaningful conversation on a variety of networking topics.
  2. To enable students to analyze networking requirements, ask proper networking questions, and know where to seek answers to those questions.
  3. To enable students to acquire sufficient knowledge and self-confidence to undertake such tasks as design, administration, and troubleshooting of networks after a couple of years of working experience.
Our Objective:
 
Our objective in this practical oriented course is to maximize the educational experience of those students who bring a sincere effort and serious interest in the subject matter to the classroom

Work Load:

2 hours lecture per week

1 hour tutorial per week

3 hours for projects, assignments, field work etc per week

4 hours for preparatory work by a student per week

Modular Credit: 4

Teaching Modes:

Weekly Lectures of 2 hours, 1 hour tutorial, and programming assignments on client/server application development. 

Pre/Co requisites:

Prerequisites: CS2105
Co-requisite: CS3103L
Preclusions: EE3204/E, EE4210; EEE and CPE students are not allowed to read this module
Cross-listing(s): NIL

Since prerequisite for CS3103 is CS2105, it is assumed that you have basic knowledge of networking.  If you are an exchange student, you must have knowledge of computer networks like Local Area Networks, Ethernet, IP addressing, basic principles of IP routing and TCP.
