Tool: TCP Stream Analysis

TCP/IP stream analysis tool

This tool is part of a series of utilities  meant to illustrate the use of the Unsniff Scripting API and to motivate you to write your own tools.

TCP Stream AnalysisTCP is arguably the most important protocol in the internet today. Under the hood, TCP features complex algorithms for congestion control. TCP attempts to seek the ideal bandwidth rate dynamically on any given link. It constantly attempts to push the transfer rate higher and periodically pulling back when it encounters errors. Observing the behavior of TCP is quite a revealing experience about rate control and error recovery. We present a utility here that detects retransmissions, out of order segments, duplicate acks.  It can produce charts that plot the congestion window, advertised window, in-flight data, sequence number analysis and much more.
