System and method of segment protection in a communication network

摘要

Embodiments of the present invention described herein, discloses a method and a system for segment protection system in an Ethernet communication network. In one embodiment herein, a ‘periodic integrity check’ message frame being created at the source-node and is multicasted to the destination-node directly and via the peer node(s) within a segment protection domain. A Σ1 receiver is configured at the destination-node for receiving the multicasted message frames. The Σ1 receiver ‘selects’ only single message frame from the multicasted message frames being received at all maintenance points, for maintaining at least one fault-less path between the source-node and the destination-node.

1. A method of segment protection in a communication network, the method comprising the steps of:
configuring at least one segment protection domain within the network, the segment protection domain (SPD) comprising a source-node, a destination-node, and at least one peer node, each node having multiple ports; creating a periodic integrity check message frame at the maintenance point on the source-node; multicasting said message frame to the destination-node directly and via the peer node(s); configuring a Σ1 receiver at the destination-node for receiving multicasted message frames; configuring a plurality of maintenance point on the destination-node, each receiving one message frame to be delivered to the destination node; andenabling the Σ1 receiver to select only single message frame from the multicast message frames being received at all maintenance points, and thereby maintaining at least one fault-less path between the source-node and the destination-node.
