Any traffic to or from the LAN passes through it. Consider node # 1 running a FTP server, and node # 5 is downloading a file of size 4 MB. However, the link between node # 2 and # 3 is fault. It drops packets with a fixed probability of 0.2.
Implement a link error model to reflect this. It may be noted here that the file download time will be more than the we had in exercise # 2 of experiment # 1. Try different values of the simulation time to ensure that the file has been entirely transferred. Is the plot of bytes received a linear curve or non-linear? Presence of link errors cause one or more packets to be retransmitted. Verify this from the 'Packet Retransmissions' plot.
Measuring Network Performances Bottleneck in the network Consider a dumbbell topology with eight nodes as shown as in the following figure. Consider nodes# 2 and 3 to be two routers connecting two different networks.
When the bandwidth of the link 2-3 is much lower than the sum of bandwidths of the other links in the network, it act as a bottleneck. Assume node # 0 running a FTP application (over TCP) and sending data to node # 6. Node # 1 is sending CBR data node # 7. Assume all the links except 2-3 has a bandwidth of 1 Mb, propagation delay of 10ms and queue type as DropTail.
(All are duplex links). 50 Tasks: The link 2-3 has a propagation delay of 10 ms.
Vary it's bandwidth from 0.5 Mb to 2.5 Mb in steps of 0.25Mb. Compute the throughput for node # 3 in each case Plot the throughput vs. Bandwidth data in the 'Custom Plot' section below Based on the above plots, suggest what should be the recommended bandwidth of the link 2-3. Now, plot the end-to-end delay between nodes 0 and 6 for the above chosen values of link 2-3 bandwidth. Revisit your previous answer (i.e.
