1. A method of determining validity of path information corresponding to a transmission path between a monitoring peer and a monitored peer in a data communication network, the method comprising:

  • monitoring unsolicited data received from a monitored peer via a reverse transmission path associated with a forward transmission path identified by path information;

    monitoring any data sent to the monitored peer using the path information;

    performing validity tests by a 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; and

    invalidating the path information if a validity test fails.
