World Wide Web (WWW) Traffic Analysis Research

Chitra94 is a tool that can be used to analyze trace data, including traces of traffic from the WWW. (A new release of the tool, Chitra95 is expected in Fall 1995.) The trace formats currently supported are "common log format" and the TCPdump tool. The tool is currently still under development. This release provided is an alpha version. Please understand that you use this verson at your own risk.
