Abstract
After statically provisioned paths are created through an Ethernet network, trunks may be created to extend along those paths. The trunks extend between pairs of NNI interfaces on either end of the path, and Ethernet OAM may be run over the trunks to detect connectivity along the paths. Service instances and service groups may be provisioned over particular paths through the network. Each service instance/service group is associated with a trunk and the Ethernet OAM service on the trunk may be used to provide Ethernet connectivity OAM for the service instance/service group. Upon detection of a failure on the trunk, the service instances/service groups associated with the trunk may be caused to failover to an alternate path through the network. Thus, a single Ethernet OAM service instance may be used to provide connectivity verification so that connectivity detection does not need to be performed on each individual service instances/service group.
