Abstract: The present document relates to a tunnel multiplexing method for a linear protection group and a tunnel tail node. The method includes: setting linear protection configuration information, wherein a public network label is configured associatively with an active/standby status of its corresponding tunnel, and a private network label is configured associatively with an active/standby status of a valid tunnel of a protection group corresponding to the private network label; after receiving a data message, a tunnel tail node searching for active/standby status corresponding to the public network label and the private network label according to the public network label and the private network label in the data message, and judging whether the active/standby status corresponding to the public network label is consistent with the active/standby status corresponding to the private network label; if consistent, the tunnel tail node forwarding the data message, and if inconsistent, discarding the data message.

Abstract: The present invention discloses a method and system for processing an MPLS-TP tunnel protection, including: a tail node of a multiprotocol label switching transport profile (MPLS-TP) tunnel, after receiving a data message, querying a private network label table of the tail node according to a private network label carried in the data message, and acquiring a value of a protection flag field; when judging that a protection type of the MPLS-TP tunnel is 1+1 according to the value of the protection flag field, acquiring a value of a difference bit number field, and determining a value of a corresponding difference bit in a public network label of the MPLS-TP tunnel; and acquiring a value of a decision field, and carrying out corresponding processing on the data message according to a comparison result of the value of the difference bit and the value of the decision field.

With the present invention, the processing performance of the data message on the MPLS-TP tunnel can be improved.
