Abstract:
1. A method of synchronizing AAL2 (ATM adaptation layer type 2) path states between AAL2 signaling nodes, comprising steps of: a) sending, by a AAL2 signaling node as the synchronization requesting end, a path state request message to a peer AAL2 signaling node of an AAL2 path; b) performing, by the peer AAL2 signaling node, local check on the state of an AAL2 path designated by the request message after receiving the request message; c) controlling, by the peer AAL2 signaling node, consistency synchronization processing on the AAL2 path states at two ends based on the result of the check, wherein the controlling step is initiated at a time when the local AAL2 path state of the peer AAL2 signaling node is one of “idle,” “peer block” and “local block”.
