Abstract:
1. A method for implementing shared mesh protection, the method comprising: receiving, by a first node, a message of a second type sent by a second node, wherein the message of the second type carries a second positive incoming sublabel allocated by the second node for a protection path of a first service and the second positive incoming sublabel is used to indicate a specified feature of recovery information of the first service; allocating a first positive outgoing sublabel for the protection path of the first service based on the second positive incoming sublabel, wherein the first positive outgoing sublabel corresponds to the second positive incoming sublabel; calculating a positive outgoing interface of the protection path of the first service on the first node based on routing information and allocating a positive outgoing channel for the protection path of the first service; establishing a positive binding relationship of the protection path of the first service on the first node, wherein the positive binding relationship comprises a mapping binding relationship between the positive outgoing interface and the positive outgoing channel and the first positive outgoing sublabel; transmitting the recovery information of the first service to the second node based on an indication of the first positive outgoing sublabel when knowing that a working path of the first service is faulty; and switching the first service over to the protection path of the first service based on the established positive binding relationship when knowing that the working path of the first service is faulty.
