MAC COPY IN NODES DETECTING FAILURE IN A RING PROTECTION COMMUNICATION NETWORK

摘要

Embodiments of the present invention provide a method and system for reducing congestion on a communication network. The communication network includes a network node having a first port and a second port. The network node is associated with forwarding data including first port forwarding data identifying at least one node accessible via the first port, and second port forwarding data identifying at least one node accessible via the second port. A failure associated with one of the first port and the second port is determined. The forwarding data corresponding to the other of the first port and the second port not associated with the failure, is updated with the one of the first port forwarding data and second port forwarding data corresponding to the one of the first port and the second port associated with the failure.
