  • Patent number: 10749793
    Abstract: A network node that provides egress fault protection for a primary egress node. The network node may receive a service label associated with an application from a primary egress node of a primary label switched path (LSP). The network node may use the service label to add a forwarding entry into a forwarding table associated with the primary egress node. Following a fault in the primary egress node, the network node may receive a data packet comprising an LSP label and the service label from a partial backup LSP. The network node may use the LSP label to locate the forwarding table associated with the primary egress node. The service label may be used to deliver the data packet to a destination node according to the forwarding table associated with the primary egress node.
