TCP Analyzer

This tool analyzes network traces of TCP connections. Given a Microsoft Network
Monitor trace, the analyzer provides various performance statistics and
visualizations for the captured TCP connection. Included are plots of the
time-sequence graph, round-trip time measurements, and more. The tool also
contains an analysis engine that attempts to explain what the limiting
performance factor of a particular connection was, such as limited physical
bandwidth, network congestion, or a receiver or sender window size that is too
small. The tool helps determine why a particular TCP connection is slow and
enhances understanding of what a connection is doing.

Virtual USB Analyzer

The Virtual USB Analyzer is a free and open source tool for visualizing logs of USB packets, from hardware or software USB sniffer tools. As far as we know, it’s the world’s first tool to provide a graphical visualization along with raw hex dumps and high-level protocol analysis.
