Communications system and related method for reducing continuity check message (CCM) bursts in connectivity fault management (CFM) maintenance association (MA)

摘要

In accordance with a non-limiting example, a system and method minimizes collisions between transmitted connectivity fault management (CFM) packets. Maintenance association endpoints are formed from a plurality of network switch elements to form a maintenance association. The clocks between each network switch element within the maintenance association are synchronized. A unique transmission window is assigned to each maintenance association endpoint as part of the maintenance association. A respective CFM packet is transmitted as a continuity check message (CCM) within the unique transmission window.

1. A communications system comprising:
a plurality of Maintenance Association End Points (MEP) arranged to form a Maintenance Association within the Maintenance Association have a clock synchronized with other respective clocks; and each MEP having a unique transmission window in the Maintenance Association to transmit from the MEP a respective Connectivity Fault Management (CFM) packet as a multicast Continuity Check Message (CCM).
