Packet Capture Based Post Mortem Analysis of Real Time Multimedia Applications
The project aimed at doing analysis at packet-level. It involved detailed study of real time multimedia applications like virtual classrooms using packet capture. The basic purpose was to gather relevant information related to packets like average unacknowledged data from client/server over a period of time, average rate of dropped/out of sync/retransmitted/re-acknowledged packets, find out the jitter in network, etc. for a given connection. From this knowledge, it was possible to find the signs of abnormal behavior in the network which includes jitter, defective packets(out of order, retransmitted, lost),throughput and make sense out of all the data gathered to pin point the particular packet originating from the particular source. On top of this knowledge base, statistical reports and historical analysis was done using D3 charts.
