Abstract: A service is configured by provisioning the service for a facility on a network access device (NAD). The service endpoint is created in an operationally disabled state responsive to provisioning the service. A first network interface unit (NIU) is detected connecting to the facility. The first NIU has an identification code associated therewith. The service transitions to an operationally enabled state responsive to detecting the first NIU connecting to the facility. The identification code is associated with the facility. The first NIU is detected disconnecting from the facility. The service transitions to an operationally disabled state responsive to detecting the first NIU disconnecting from the facility. A second NIU is detected connecting to the facility. The second NIU has an identification code associated therewith. The identification code of the second NIU is compared with the identification code of the first NIU.

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.
