Diagnosing problems with your multicast setup | Contributed code and patches
Please see the Beacon web page at
http://dast.nlanr.net/projects/beacon/#issues for more information -- There is a known bug with RTT right now which we are working on.
Central RTT is the reported Round Trip Time between two Beacons in the current multicast group, sent via TCP unicast back to the Central Server (in this case, "beacon2.aarnet.net.au") for the group. This allows for the reporting of Beacons that might not otherwise be able to see each other via UDP multicast.
Please share your comments, questions, bug reports, concerns, and feedback with us via the Beacon listserv. Please note this list can only be posted to by SUBSCRIBERS, in order to keep it spam-free. Non-subscriber email is automatically discarded. You can subscribe to the list by sending an email to "majordomo /at/ dast.nlanr.net", with "subscribe beacon /at/ dast.nlanr.net" (with real "at" signs, of course) in the body.
