As the number of Ethernet service instances grows, service providers will require a robust set of management tools to maintain Ethernet service networks. The positive news is that IEEE 802.1, ITU SG 13, and the MEF have been working in close cooperation to develop complimentary standards for multidomain Ethernet Service OAM. Ethernet Service OAM encompasses Fault Management and Performance Management capabilities that are incorporated in NEs that support Ethernet services. In a layered network model, these capabilities are active at the Ethernet Service Layer.
