Abstract:
Faults are detected and recovered from in a multiprotocol label switching (MPLS) network by communicating packets between a first node and a second node in the MPLS network using a set of prioritized label switch path (LSP) pairs. A failure to receive a relatively constant rate of packets during a predetermined time interval is detected at the first node. Packets are sent from the first node to the second node using a backup LSP pair responsive to detecting the failure. Packets are then sent from the second node to the first node using a backup LSP pair responsive to receiving packets at the second node on the backup LSP pair.
