Proposed improved Algorithms Transmitter sequence number training algorithm* Transmitted sequence number reset: Initialize start, mid, end sequence numbers. Initialize a counter to 0. Start = 1 (MPLS PW) or 0 (L2TPv3 PW) Mid = 32768 (MPLS PW) or 8388607 (L2TPv3 PW) End = 65535 (MPLS PW) or 16777215 (L2TPv3 PW) Send the start-seq-# Send the mid-seq-# Send the last-seq-# If count !=3, bump count and go back to step 2, once count == 3, return to normal sequence number incrementing, i.e. 2,3,4,5,6,.... This process should retrain the peer’s receiver sequence number with minimal to no packet loss. * Patent filed |
