Description
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. Mention and explain the observed values for at least 5 fields of the protocols mentioned in question 1.
Example: Source or destination IP address and port number, Ethernet address, protocol number, etc.
3. Explain all relevant protocols used by the application to achieve the important functionalities of the
application (varies with alpplication). Give reason for using those protocols. For example, important
functionalities for video streaming are ‘download’, ‘play’, ‘pause’, etc.
4. Mention at least two functionalities (mentioned in question 3) of the application and show the sequence
of messages exchanged by the application to achieve those functionalities. Check whether there are any
handshaking sequences in the application. Briefly explain the handshaking message sequence, if any.
5. Calculate the following statistics from your traces while performing experiments at three different times
(morning, afternoon, night) of the day: a) Throughput, b) RTT, c) Packet size, d) Number of packets lost,
e) Number of UDP & TCP packets, f) Number of responses received with respect to one request sent.
Report the observed values in your answer, preferably using tables.
6. Check whether the content is being sent by the application from the same source during the three
different times of the day used in question 5. If multiple sources exist, list out their IP addresses, and
explain the reason behind this.
Method of submission:
Submit a soft copy of the report, preferably in PDF format, together with your collected traces in a
zip file on Moodle. The name of the zip file should be like “Your_Rollno.zip”
(example: “140101002.zip”).
Files submitted without proper naming format will not be evaluated.
If your trace file size is larger than 2 MB, (as you will not be able to upload the file on Moodle) you
are advised to provide the OneDrive/Google Drive/Dropbox link of the traces in your report.
Note:
The deadline for submission must be strictly followed. Any submission done after the deadline
will not be considered for evaluation.
The report should not contain more than 6-7 pages.
Plagiarism (copy cases) and other unfair means will be strictly punished by awarding NEGATIVE
marks (equal to the maximum marks for the assignment).
