Abstract
Procedures, apparatuses, systems, and computer-readable media for operating primary and backup network elements (NEs). The procedure for operating the primary NE includes determining a failure in a primary path in which the primary NE is interposed. A switch-over notification message is provided via an inter-chassis communication link to a backup NE. At least one status synchronization message is communicated with at least one of the backup NE via the inter-chassis communication link and a head-end NE in accordance with a standardized protection switching protocol. The procedure for operating the backup NE includes receiving the switch-over notification message, indicating failure in a primary path, via the inter-chassis communication link. A status synchronization message is provided in accordance with the standardized protection switching protocol to a head-end NE to establish communication with the head-end NE via a secondary path.
