Abstract:
A method for providing ingress fault protection in a label switched network, comprising sending data traffic from a source node to a first label switched path (LSP) via a first ingress node, detecting a first fault using a first fault detection link between the source node and the first ingress node, sending the data traffic from the source node to a second LSP via a second ingress node in response to detecting the first fault, detecting a second fault using a second fault detection link between the first ingress node and the second ingress node, and merging the data traffic from the second LSP into the first LSP at a next-hop node of the first ingress node, wherein the data traffic is no longer sent to the first LSP via the first ingress node after the first fault.
