Analysis from the above data and activity details

...

Our set of analyzed dates consists of 24^th to 30^th December and then from 4^th Jan to 27th Jan.

24^th to 30^th December was when university was back to normal routine after strike holidays. In that case, the analysis is at the correct data. The important observations at this data were that high RTTs were observed from 12am to 4am and at 10am to 1pm.

From 7^th Jan to 17^th Jan there were pre-exam holidays. From 7^th to 13^th Jan average RTT was higher than previous days of 4^th Jan to 6^th Jan. This is because of students using internet for multiple purposes in their holidays. This might include social networking when youtube is blocked.  From 14^th Jan onwards high average RTTs are observed after midnight till early morning. This is possibly because students have now started preparing for exams and they study at night.

Normal RTT behavior was observed on 24^th and 25^th Jan, however, high RTT after midnight were again observed on 26^th and 27^th Jan. This might be because of project submissions deadlines approaching and students working on their research projects after taking 2-3 days off  after exams.

A reason for high average RTT for UETTAXILA can be the low bandwidth allocation. As mentioned, 4MB of bandwidth is shared among 4 departments. This increases the load on network and results in congestion, long queues, hence large RTT.
