Abstract:
1. A method of configuring Maintenance Association Endpoints (MEPs) for an Ethernet Tree (E-Tree) type service instance in which a Maintenance Association includes a root MEP and a plurality of leaf MEPs, and each of the MEPs includes a plurality of remote MEP state machine instances corresponding to the other MEPs in the Maintenance Association, wherein activation of the plurality of remote MEP state machine causes each of the plurality of MEPs to exchange Connectivity Check Messages (CCMs) with the other MEPs in the Maintenance Association, wherein an improvement comprises: activating by a processor, the plurality of remote MEP state machine instances in the root MEP corresponding to the plurality of leaf MEPs; and activating by the processor or a different processor, only one of the plurality of remote MEP state machine instances within each leaf MEP, wherein the activated remote MEP state machine instance within each leaf MEP corresponds to the root MEP; wherein the activated remote MEP state machine instances cause the leaf MEPs to exchange CCMs with the root MEP, but not with other leaf MEPs.
