One website is of a news channel and the other one is a website forlive streaming. The students are required to capture packets of multiple images from the news channelwebsite and capture packets from the live stream website while streaming for 10 minutes once at MIT in agroup and then on their home network individually. So at the end, there will be four trace files, two for eachwebsite, two captured on MIT network and two on students’ home networks. The websites to access are: complete report must be submitted on Moodle within due date. The report has following four mainparts:Part 1:The first part of the report should be about general statistics of all four captures using Wireshark that mustinclude:

IP addresses of the client and serverPart 2:The second part of the report must include screen shots of packet capture, screenshots of different statisticsfrom Wireshark and complete analysis of those screenshots for both websites for all two networks. Onlyscreenshots of the graphs or other statistics will not get any marks as those must be analysed in detail todiscuss the quality of service for a particular application. The students are required to analyse the networkperformance for the assigned websites considering following aspects:College Homework Help

1. Throughput2. Round Trip Time3. Packet LossWhile collecting statistics please make sure, you are looking at the right flow as your Wireshark file may havepackets from other applications and flows as well. Figure 1 on next page shows the throughput graphgenerated by Wireshark and source and destination addresses are clearly shown. You need to collect statisticsfor flows which are from server to client.MN504 Networked Application Management Assignment 2 Page 3 of 5Prepared by: Dr S M Farhad Moderated by:

The throughput graphs and TCP retransmission statisticsfor web page transfer and live streaming (provided in part 2) need to be compared with each other and for alltwo networks. The differences of the performance to be identified and reasons must be provided for suchdifferences.

Part 4:Students need to download, install, use and compare another free network performance measurement toolfrom the Internet on their home computer. One possible option is Microsoft Message Analyser from‐au/download/details.aspx?id=44226. The tool should be used to analyse thenetwork traffic captured while accessing one of the news websites mentioned in Table 1. The chosen toolshould be compared with Wireshark on the basis of following criteria:1.
