Abstract
A method, system, peers and computer programs determine validity of path information corresponding to a transmission path between a monitoring peer and a monitored peer in a data communication network. The monitoring peer monitors unsolicited data received from the monitored peer via the reverse transmission path identified by the path information and further monitors any data sent to the monitored peer using the path information. Validity tests are performed by the monitoring peer for the path information to restore complete confidence in its validity in a way where the rate of testing is proportional to the rate of receiving unsolicited data from the monitored peer and to the rate of sending data to the monitored peer. The monitoring peer invalidates the path information if the validity test fails.
