METHOD AND APPARATUS FOR TRANSMITTING AND PROCESSING EXTENDED REMOTE DEFECTION IDENTIFICATION MESSAGE AND EXTENDED BACKWARD DEFECTION IDENTIFICATION MESSAGE
The present invention discloses a method and apparatus for transmitting and processing an extended remote defection identification (RDI) message and an extended backward defection identification (BDI) message, wherein the method for transmitting and processing the extended BDI message comprises: an end node on a multi-protocol label switching (MPLS) transmission path generating the extended BDI message according to requirements, and transmitting the extended BDI message along the MPLS transmission path according to a path identifier (ID) corresponding to the extended BDI message; and when determining that the extended BDI message needs to be processed, a node on the MPLS transmission path that has received the extended BDI message identifying a type length value (TLV) message contained in the extended BDI message, and analyzing and processing an identifiable TLV message. The present invention also discloses an apparatus for transmitting and processing an extended BDI message, thus not only assuring the compat
