In one embodiment, a maintenance intermediate point (mip) receives a packet traveling along a multi-protocol label switching (mpls) label switched path (lsp) that extends from a first maintenance end point (mep) to a second mep. The receiving mip decrements a time-to-live (ttl) value in a header of the packet.

Method for establishing associated bidirectional label switching path and system thereof
The disclosure discloses a method and a system for establishing an associated bidirectional label-switched path (lsp). The method includes the following steps: a head node sends a path message for establishing or updating an lsp to an end node, wherein the message carries an object for identifying association; the end node sends to the head node a path message for establishing or updating an lsp as a reverse lsp corresponding to the above lsp, wherein the message carries an object for identifying association; in the case that the attributes of the objects for identifying association carried in the path messages sent by the head node and the end node are the same, the lsp and the reverse lsp are associated with each other by the head node and the end node and become an associated bidirectional lsp.
