TCP Analysis Tools

Ethereal: Using Time-sequense graph to analyze TCP sequence numbers

TCPtrace:

1, using Tcptrace's outstanding Data graph to analyze

2, Congestion Window Analysis: Receive window and send buffer size is limited in case

Congestion window = sent unacknowledged data + number of packets

3, send buffer analysis receiving serial port and congestion window is unrestricted, sent unacknowledged data represents the send buffer size, analysis of the sending buffer size is very effective.

Method:

1, using Tcptrace to convert the capture package file *.cap to *.xpl

2, the use of Iplot will *.xpl picture outstanding Data graph
