Abstract: A method implemented by a node in a network utilizing Multiprotocol Label Switching (MPLS) includes performing a convergence procedure to discover the topology of a network in which multiple nodes are arranged; and upon determining that the topology of the network is a ring topology whereby the node is connected to two neighboring nodes by a respective link, creating a first table for a first link, the first table including labels representing at least a portion of a label stack for allowing the node to transmit packets to another node in the network in a clockwise (CW) direction around the ring; and creating a second table for a second link, the second table including labels representing at least a portion of a label stack for allowing the node to transmit packets to another node in the network in an anti-clockwise (ACW) direction around the ring.

Abstract: A Continuity Check (CC) protocol optimization method in a switch includes operating a plurality of CC sessions with a peer switch, wherein, for CC intervals, N sessions of the plurality CC sessions are set to a short interval and M sessions of the plurality of CC sessions are set to a long interval, wherein N and M are integers; switching a first session of the N sessions with a second session of the M sessions based on one of a fault and user provisioning; and exchanging the CC intervals between the first session and the second session subsequent to the switching.
