Abstract
A system and method of demultiplexing Provider Backbone Bridging Traffic Engineering (PBB-TE) service instances. The method is used when monitoring service instances between a first bridge port and a second bridge port by exchanging CFM frames over each service instance. The CFM frame is received by the second bridge port where the complete ESP—3-tuple is demultiplexed. The CCM frames may be demultiplexed by a Full Traffic Engineering Service Instance Multiplex Entity which demultiplexes both the source address value and destination address value of the CCM frames.
