Abstract
A method for teleprotection over a segment routed network comprises receiving network requirements for communication between a first teleprotection relay and a second teleprotection relay, the first teleprotection relay associated with a first router of the segment routed network, and the second teleprotection relay associated with a second router of the segment routed network, identifying a primary path from the first router to the second router satisfying the network requirements, determining a congruent reverse of the primary path satisfies the network requirements, sending, to the first router, the primary path, the first router routing traffic from the first teleprotection relay to the second teleprotection relay using the primary path, and sending, to the second router, the congruent reverse of the primary path, the second router routing traffic from the second teleprotection relay to the first teleprotection relay using the congruent reverse of the primary path.
