3. ©2005 SURFnet, bigvideo wg, I2 MM, may 2, 2005 3 Beacon Reserved our own worldwide unique multicast group: 233.4.79.11 Reports on http://beta.surfnet.nl/beaconclient/central_loss.html http://beta.surfnet.nl/beaconclient/central_loss.html Sample config file: http://beta.surfnet.nl/beaconclient/beacon.conf.bigvideo http://beta.surfnet.nl/beaconclient/beacon.conf.bigvideo If the beacon is broken, that gives you higher confidence the problem is not just user error or host issues. It is sometimes possible to use the beacon as the constantly active source and receiver for debugging. It will not catch new/transient problems with source knowledge or state creation (the tree has been built).
