<p>Methods and systems are provided for recovering from an interruption in, or failure of, an L2TP tunnel connection, such that reconnection of the tunnel is not required. According to various embodiments, redundant storage of tunnel state information is used to avoid having to reconnect an interrupted or failed tunnel session. According to various other embodiments, extraction of sequence numbers from a peer L2TP endpoint server is achieved by subdividing the set of all available sequence numbers into an appropriate number of divisions, and sending a control message having a sequence number from each of the divisions to the peer endpoint server to elicit a response.</p> |
