摘要: A method of controlling traffic forwarding in a Provider Backbone-Traffic Engineered (PBB-TE) network. A protection group (PG) is defined, and including N working Traffic Engineered Service Instances (TESIs) and M protection TESIs. An Automatic Protection Switching Protocol Data Unit (APS PDU) is defined, which includes information defining at least a state of the protection group. This APS PDU is forwarded only through the protection TESI(s).
