This document outlines 3 programming assignments involving network simulations. The first asks to create 2 nodes with a duplex link using UDP and CBR to check packet statistics. The second involves 3 nodes with TCP and FTP to check packet statistics and calculate delivery ratio. The third is to simulate the network in the figure with n0 to n4 using TCP and n1 to n5 using UDP to calculate delivery ratio.

1. Assignment

2. 1. Write a program to create 2 Nodes, connect them in
to duplex-link and attach UDP protocol and CBR traffic
for packet transmission. Check the number of packet
receive, number of packet drop, number of packet
enqueue, and number of packet dequeue: in this
simulation.

3. 2. Write a Program for simulation, to create 3 Nodes
with duplex link, using TCP protocol and FTP traffic with
1Mbps bandwidth and 10ms delay packets are send
from source node to destination node. Check the
number of packet receive, number of packet drop,
number of packet enqueue, and number of packet
dequeue: in this simulation. Also calculate the packet
delivery ratio and compared with previous simulation
results.

4. 3. Write a program for a simple network
according to the following figures, n0 node
connected to n4 by TCP and n1 node connected
to n5 by UDP. Calculate the packet delivery ratio.
