Abstract:
A device may provide path data identifying a primary path and one or more alternate paths for segment routing traffic in the network, and may receive performance data indicating a performance degradation in the primary path. The device may determine that the performance data satisfies a first threshold, and may request, based on the performance data satisfying the first threshold, alternate path performance data. The device may receive the alternate path performance data based on the request, and may compare the alternate path performance data for the one or more alternate paths. The device may select a particular alternate path, of the one or more alternate paths, based on comparing the alternate path performance data for the one or more alternate paths, and may trigger, based on the performance data satisfying a second threshold, a failover of the traffic from the primary path and to the particular alternate path.
