Abstract:
A node includes a plurality of ports configured to provide a service over a primary Multi-Segment Pseudowire (MS-PW) and a backup MS-PW in a network; a switching fabric interconnecting the plurality of ports; and a controller communicatively coupled to the plurality of ports and the switching fabric, wherein the controller is configured to receive a pseudowire status message for each of the primary MS-PW and the backup MS-PW, determine a Signal Degrade condition on one of the primary MS-PW and the backup MS-PW based on the pseudowire status message, and cause a switch of the service to an inactive one of the primary MS-PW and the backup MS-PW based on a Signal Degrade condition on an active one of the primary MS-PW and the backup MS-PW. The controller can further provide a trap to a management system based on the determined Signal Degrade condition.
