  • Apparatus and method for establishing a repair path
    Patent number: 10326692
    Abstract: A communication network is configured to operate a remote Loop-Free Alternate (LFA) procedure. Prior to detecting a link failure or switchover event associated with a protected link within a current path between a source node and a destination node of the communication network, a Point of Local Repair (PLR) node is configured for the protected link, and a repair tunnel endpoint node is configured for the PLR node. In response to detecting a link failure or switchover event associated with the protected link, a repair path is established between the source node and the destination node. The repair path is routed via the repair tunnel endpoint node, and the route of the repair path excludes the PLR node and the protected link.

  • Apparatus and method for establishing a repair path
    Patent number: 10075367
    Abstract: A method and apparatus is provided for establishing a repair path between a source node (101) and a destination node (105) in a communication network configured to operate a remote Loop-Free Alternate, LFA, procedure. The method comprises the steps of: prior to detecting a link failure or switchover event associated with a protected link, within a current path between the source node (101) and the destination node (105), performing the steps of: pre-configuring a Point of Local Repair, PLR, node (106) for the protected link (step 301); and pre-configuring a repair tunnel endpoint node (102) for the PLR node (step 303).
