Detailed information: The network contains: 0 3 nodes in the first shared bus operating under CSMA 0 3 nodes in the second shared bus operating under CSMA 2 nodes in the point-to-point link Note that Nodes 2 and 3 in Figure 1 have two network interfaces, one for each link to which they are connected The applications running in the network are: UDP Echo Server at Node 1: Listening on port 21 UDP Echo Client at Node 5: Sends 2 UDP Echo packets to the server at times 4s and 7s Enable packet tracing only in Nodes 2 and 4. Verify that the network behavior is as expected, by capturing the packet traces and utilizing Wireshark to analyze them. Submission materials: Generate a brief report explaining: 1) the experimental setup: indicate which part of the code have you modified 2) the results: comment and include a screenshot of the packet traces in Wireshark 3) the conclusions: what did you learn for each of the two tasks. In your submission, include also your modified.cc files. Remember: the laboratory assignments can be conducted either individually or in couples. If you want to work in couples, please enroll in a Computer Lab Team in Canvas. Then, only one of the team members will need to submit the assignment. Computer Lab Team 1 Cu Computer Lab Team 2 Co
