  • Patent number: 9161106
    Abstract: Embodiments of the present invention disclose a method for implementing shared mesh protection includes: receiving, by a first node, a message of a second type sent by a second node, where 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, by the first node, a first positive outgoing label for the protection path of the first service based on the second positive incoming sublabel, where the first positive outgoing label corresponds to the second positive incoming sublabel; and 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.

  • Patent number: 8149693
    Abstract: A method of implementing association in an Automatic Switched Optical Network. When an initial node of the 1+1 protection service is outside the ASON, it associates the primary service and the slave service to realize 1+1 protection. This invention includes: a node of a first associated service acquiring path information of a second associated service from a node of the second associated service, and associating the second associated service to the first associated service according to the path information of the second associated service.
