The Multicast Beacon http://dast.nlanr.net/projects/Beacon/ - See user contributions before installing source! - Windows app hard to install
Beacon • Reserved our own worldwide unique multicast group: 233.4.79.11 • Reports on http://beta.surfnet.nl/beaconclient/central_loss.html • Sample config file: 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).
Other tools • rtpqual ftp://ftp.ee.lbl.gov/rtpqual.c • Simple Multiprotocol Multicast Signal Quality Meter • very useful for establishing a receiver (even if the multicast is not using RTP) • also useful for finding packet loss problems and whether they are periodic or not • If you know the group but not the port, you can use rtpqual to join with any port, then use tcpdump to find out which port the traffic is actually going to. • Graphical user interface developed byLaurence Kirchmeier (Merit) • Mtrace ftp://ftp.parc.xerox.com/pub/net-research/ipmulti/mtrace5.2.tar.gz • Simple host-based rpf check tool • Iperf http://dast.nlanr.net/projects/iperf • Source/client traffic generator that can generate multicast packets (requires access to device at both ends of path)
