WWW Traffic Engineering Tool Interface

We have started developing a WEB-based interface for our traffic analysis tools (msa and lb). To access the interface you only need a java-capable WWW browser. The current version of the interface is available here.

The msa tool

The following executables are currently available: *Note* that the above files are compressed with gzip, so you will have to unzip them. The source code is not available yet.
There exists a man page, and a collection of frequently encountered problems.

A sample trace file (MPEG-1 compressed video of Star Wars) can be found here. The trace contains 40000 epochs, with each epoch having duration 40 msec. Note that the trace file MUST have the extension .tr

The following executables are currently available:
