Abstract
This invention is related to a method for Fast Connectivity Fault Management (CFM) of a service-network in the realm of Carrier Ethernet, comprises steps of: learning spanning tree topology of the service-network, exchanging Fast Connectivity Check Messages (Fast-CCM)s between the adjacent service-nodes of the tree, terminating the Fast-CCMs so received, to learn the fault, in the service-network, upon failure to receive a Fast-CCM through a service-port, and pro-actively notifying the fault by service nodes on either side of the faulty service-network.
