Abstract:
A Maintenance Association and corresponding method for configuring maintenance entities for Ethernet Tree (E-Tree) type service instances. A root MEP communicates with each of a plurality of leaf MEPs. Remote MEP state machine instances are activated within the root MEP for each of the plurality of leaf MEPs. Within each leaf MEP, however, only the remote MEP state machine instance for the root MEP is activated while leaving the remote MEP state machine instances for all other leaf MEPs in an inactive state in which Connectivity Check Messages (CCMs) are not exchanged.
