Diagnosing problems with your multicast setup | Contributed code and patches
Central Loss is the reported loss between two Beacons in the current multicast group, sent via TCP unicast back to the Central Server (in this case, "jhereg.ncsa.uiuc.edu") for the group. This allows for the reporting of Beacons that might not otherwise be able to see each other via UDP multicast.
