BridgeSim is a simulation environment for studying the behavior of ethernet bridging protocols.  Currently, RSTP (802.1w) is the only bridging protocol supported.  BridgeSim is heavily based on rstplib version 1.1.02 by Alex Rozin and Michael Rozhavsky.

BridgeSim is open source software released under the LGPL.

For more information, see the README file that comes with the release.


On May 2, 2005, BridgeSim version 0.03 was released.  Get it here.

This release should be identical to version 0.02 except for 2 minor changes: First, I corrected the COPYING file to include the right version of the LGPL. Second, I used newer versions of automake and friends to prepare the release.

The archive has been packed with tar and compressed with bzip2. Recent versions of tar should be able to open it with the command
tar jxvf bridgesim-0.02.tar.bz2

If that doesn't work, try
bunzip2 bridgesim-0.0.2.tar.bz2 ; bridgesim-0.02.tar


BridgeSim is far from complete.  If you would like to participate in its development, mail Andy Myers (acm "at" for more information.
