| Sl. No. | Course Objectives |
|---|---|
| 1 | Introduction to different commands commonly used in networking. |
| 2 | Provide hands on experience related to error detection, routing and congestion control algorithms. |
| 3 | Simulate the working of different networks using simulation software. [NS2/ NS3] |
| Weeks | List of Programs |
|---|---|
| PART-A: Implement the following using C++/Java/Python | |
| 1 | Write a program to sort frames using appropriate sorting techniques. |
| 2 | Write a program for error detecting code using CRC-CCITT (16- bits). |
| 3 | Write a program to find the shortest path between vertices using bellman-ford algorithm. |
| 4 | Using TCP/IP sockets, write a client – server program to make the client send the file name and to make the server send back the contents of the requested file if present |
| 5 | Write a program on datagram socket for client/server to display the messages on client side, typed at the server side. |
| 6 | Write a program for simple RSA algorithm to encrypt and decrypt the data. |
| 7 | Write a program for congestion control using leaky bucket algorithm and token bucket algorithm. |
| 8 | Write a program to implement random early detection (RED) congestion control algorithm. |
| PART-B: Simulation Experiments using NS2/ NS3/ NetSim or any other suitable simulation software | |
9 |
Implement three nodes point – to – point network with duplex links between them. Set the queue size, vary the bandwidth and find the number of packets dropped. |
10 |
Implement transmission of ping messages/trace route over a network topology consisting of 6 nodes and find the number of packets dropped due to congestion |
| 11 | Implement an Ethernet LAN using n nodes and set multiple traffic nodes and plot congestion window for different source / destination. |
12 |
Implement simple ESS and with transmitting nodes in wire-less LAN by simulation and determine the performance with respect to transmission of packets |
