Title: Ethernet oam at intermediate nodes in a pbt network
Inventor: TSANG DAVID
IPC: H04L69/40
Filed: 2007-10-31
Abstract: OAM may be implemented at an intermediate node on a PBT trunk in an Ethernet network by causing OAM frames to be addressed to the PBT trunk endpoint but causing the OAM frames to carry an indicia (Ether-type, OpCode, TLV value or combination of these and other fields) that the OAM frames are intended to be used for intermediate node OAM functions. The Ether-type, OpCode, and TLV values may be standardized values, or vendor specific values may be used. Addressing the 0AM frames to the PBT trunk endpoint enables the OAM frames to follow the PBT trunk through the network. The 0AM indicia signals to the intermediate nodes that the 0AM frames are intended to be used to perform an intermediate node OAM function. The 0AM frames may contain reverse trunk information to prevent the intermediate nodes from being required to store correlation between forward and reverse trunks.
