Abstract
A method for transmitting a Connectivity Fault Management (CFM) message of Ethernet includes: receiving a CFM message transmitted from a source node, the CFM message including identifier of a path and a connection maintenance target address; determining whether the connection maintenance target address matches address of a receiving node, and if yes, terminating the CFM message; otherwise forwarding the CFM message to a next hop based upon the path identifier of the path. Another method and a system for transmitting a CFM message of Ethernet, a node for transmitting a CFM message of Ethernet, and a node for receiving a CFM message of Ethernet are also disclosed. With the invention, a CFM message may be forwarded according to information of a Medium Access Control (MAC) address and a Virtual Local Area Network Identifier (VLAN ID) of a path identifier where a monitored service is located, and thus may be forwarded correctly in a Provider Backbone Bridge Traffic Engineering (PBB-TE) network.
