Protecting a label switched path egress without using downstream labels
A computer program product comprising computer executable instructions stored on a non-transitory computer readable medium such that when executed by a processor cause a network element to protect a label switched network against egress node failure by receiving a primary service label and a backup service label from an upstream node in the network, receiving data traffic comprising the primary service label from the upstream node for transmitting to a downstream node in the network, determining a status of a primary egress node in the network, the primary egress node being associated with a primary label switching path, forwarding the data traffic according to a primary label switching path when the primary egress node is operating properly, and replacing the primary service label with the backup service label and forwarding the data traffic according to a backup label switching path when the primary egress node has failed.
