Assignment 2: Analysing network packets using Wireshark

Questions: 1. List out all the protocols used by the application at different layers (only those which you can figure out from traces). Study and briefly describe their packet formats. 2. Highlight and explain the observed values for various fields of the protocols. Example, Source or destination IP address and port no., Ethernet address, protocol number, etc. 3. Explain the sequence of messages exchanged by the application for using the available functionalities in the application. For example: upload, download, play, pause, etc. Check whether there are any handshaking sequences in the application. Briefly explain the handshaking message sequence, if any. 4. Explain how the particular protocol(s) used by the application is relevant for functioning of the application. 5. Calculate the following statistics from your traces while performing experiments at different time of the day: Throughput, RTT, Packet size, No. of packets lost, number of UDP & TCP packets, number of responses received with respect to one request sent. Report the observed values in your answer, preferably using tables. 6. Check whether the whole content is being sent from same location/source. List out the IP addresses of content providers, if multiple sources exist and explain the reason behind this.
Submit a soft copy of the report, preferably PDF, together with your collected traces in a zipped form on Moodle. The name of the zip file should be like “Your_Rollno.zip” (example 130101002.zip). Files submitted without proper naming format will not be evaluated. If your trace file size is larger than 2MB (as you won't be able to upload the file in Moodle), you are advised to provide the Drive/Dropbox link of the traces in your report.
Note: Report should not contain more than 6-7 pages. Copy cases will be strictly punished by awarding "ZERO" Marks.
