 LEARNING OUTCOMES Top
The main objective of this course is to provide an opportunity for the students to have hands-on experience with,
  • Configuring and interconnecting LANS using networking devices/technologies (routers, switches, hubs),
  • Networking protocols (DHCP, DNS, RIP, OSPF, ICMP, TCP, UDP, IP multicast, Wireless LAN, VLAN protocols, SIP, SSL),
  • Networking tools (tcpdump, netstat, ping, traceroute),
  • and developing network applications (Client/Server, P2P) using Socket interface.
Additionally, the course covers the following topics in greater technical depth than a basic networking course:
VLAN, Wireless LAN (802.11b/g/n), fundamentals of Cryptography and network Security protocols (SSL, PGP, etc, Multicast routing and Higher level protocols (HTTP, FTP, SMTP, POP, IMAP, DNS, VoIP with SIP and H.323 protocol suites).

Module Theme: "Build, Configure and Observe the Protocols in Action and Develop Applications with the Protocols"


 PREREQUISITES Top

Prerequisites: EE3204 - Computer Communication Networks I

If you are an exchange student, you must have basic knowledge of computer networks like Local Area Networks, Ethernet, Wireless Networks, IP addressing, basic principles of IP routing, ICMP, ARP, DHCP, TCP and UDP.


Pre-Clusions: CS2105 Introduction to Computer Networks, CS3103 Computer Networks & Protocols and CS3103L Computer Networks Laboratory

Modular Credits: 3.0 MC


 



 TEACHING MODES Top
Weekly Lectures followed by Laboratory sessions are planned for this course.

Lectures: Lectures are designed to impart necessary theoretical knowledge required to do the lab experiments.

Labs: Weekly Laboratory sessions with periodic briefing spread out throughout the course. Students will be given a quiz to assess their knowledge on the topic and preparedness before they start each experiment.

There is  NO webcast or podcast for this course. For make-up lectures (if any), we may arrange for webcast.

Solutions/Answers for the Quiz questions will NOT be published/given. You should find the answers by doing the experiment and/or discussing with the tutors after receiving the graded quiz papers. You are also encouraged to use the ivle-forum to discuss the answers with your classmates.

 SYNOPSIS Top

Lab Etiquettes:

 

Laboratory meets 10 sessions of 2 hours each.  Please see the lab schedule for details.
Laboratory groups For all the experiments, students in each lab session are to work as groups of 2. Each group of student will be assigned a group number within their session.
Laboratory location COM1-B-02 (Data Comm Lab 3) 
Laboratory registration Each student should register for lab session individually using the On-line registration system.
Laboratory policy Attendance, punctuality, preparedness and discipline are very important ingredients for working in the CS3103 lab. 

NO MAKEUP LAB SESSIONS WILL BE ENTERTAINED. In case you miss a lab for a valid reason, you must join in the same week with another group after taking permission from the lab instructor. 

Late comers policy Late comers to the lab will be penalized as follows: 
15 mins       20% off the lab weightage for that expt
30 mins       50% off the lab weightage for that expt 
45 mins       No credit for that  lab experiment. 
Cheating Policy Students are encouraged to discuss their lab experiment and results with others. However, the lab questionnaire which is turned in must have been produced by the student group themselves. If any cheating in way of copying is noticed, no credit may be given for the submission. 

Note that bringing past year questionnaires into the laboratory is also considered as cheating. 

Lab Questionnaire We have observed in the past that many student groups spend a lot of time in capturing screen to produce a cosmetically good looking report, without spending enough time to understand the basics of networking. Students seem  to work towards the goal of writing a beautiful report. This really defeats the purpose of having lab sessions, where we expect students to explore new ways of connecting, try new options with network commands, etc. 

Instead of writing a lab report for each experiment, a lab questionnaire containing simple questions relevant to the experiment is given. All groups must answer the questions during the lab session itself and return the questionnaire before leaving the lab.  

Pre-Lab Quiz

There will be a 15 minutes quiz before each lab session that would examine the student's understanding of the topic and preparedness to do the experiment independently.  It is closed book quiz.
