Abstract
A method and network element include receiving, at a receiver node, at least one of sender timestamps and sequence numbers in continuity check (CC) frames sent by a sender node; determining receiver timestamps at the receiver node; detecting instability based on one or more of the at least one of sender timestamps and sequence numbers and the receiver timestamps; and performing a remedial action based on the detecting instability. The CC frames can include Bidirectional Forwarding Detection (BFD) or Continuity Check Message (CCM) frames which are regularly transmitted in a session, but do not currently include timestamps or sequence numbers.
