Method and system for teleprotection over segment routing-based networks

A system for teleprotection over a segment routed network, the system comprising:

• one or more processors;
• one or more memories storing instructions which, when executed by the one or more processors, cause the one or more processors to:
• receive, from a first teleprotection relay, one or more network requirements for communication between the first teleprotection relay and a second teleprotection relay, wherein the first teleprotection relay is associated with a first router of the segment routed network, and wherein the second teleprotection relay is associated with a second router of the segment routed network;
• identify a primary path from the first router to the second router satisfying the one or more network requirements;
• determine a congruent reverse of the primary path satisfies the one or more network requirements and that the first router and the second router are reporting similar latency values;
• send, to the first router, the primary path, wherein the first router routes traffic from the first teleprotection relay to the second teleprotection relay using the primary path;
• send, to the second router, the congruent reverse of the primary path, wherein the second router routes traffic from the second teleprotection relay to the first teleprotection relay using the congruent reverse of the primary path;
• identify a backup path from the first router to the second router satisfying the one or more network requirements, wherein the backup path is completely separate from the primary path;
• determine a congruent reverse of the backup path satisfies the one or more network requirements;
• send, to the first router, the backup path;
• send, to the second router, the congruent reverse of the backup path, wherein the backup path is used in response to a failure of the primary path;
• receiving a first latency report from the first router or the second router;
• receiving a second latency report from the first teleprotection relay or the second teleprotection relay;
• and
• comparing the first latency report and the second latency report to determine if the first teleprotection relay or the second teleprotection relay are a source of latency.

A non-transitory computer readable medium storing instructions for teleprotection over a segment routed network, the instructions, when executed, cause:

• receiving, from a first teleprotection relay, one or more network requirements for communication between the first teleprotection relay and a second teleprotection relay, wherein the first teleprotection relay is associated with a first router of the segment routed network, and wherein the second teleprotection relay is associated with a second router of the segment routed network;
• identifying a primary path from the first router to the second router satisfying the one or more network requirements;
• determining a congruent reverse of the primary path satisfies the one or more network requirements and that the first router and the second router are reporting similar latency values;
• sending, to the first router, the primary path, wherein the first router routes traffic from the first teleprotection relay to the second teleprotection relay using the primary path;
• sending, to the second router, the congruent reverse of the primary path, wherein the second router routes traffic from the second teleprotection relay to the first teleprotection relay using the congruent reverse of the primary path;
• identifying a backup path from the first router to the second router satisfying the one or more network requirements, wherein the backup path is completely separate from the primary path, wherein the backup path is used in response to a failure of the primary path;
• determining a congruent reverse of the backup path satisfies the one or more network requirements;
• sending, to the first router, the backup path;
• sending, to the second router, the congruent reverse of the backup path;
• receiving a first latency report from the first router or the second router;
• receiving a second latency report from the first teleprotection relay or the second teleprotection relay;
• and
• comparing the first latency report and the second latency report to determine if the first teleprotection relay or the second teleprotection relay are a source of latency.
