A ring node N belonging to a resilient MPLS ring (RMR) provisions and/or configures clockwise (CW) and anti-clockwise (AC) paths on the RMR by: (a) configuring two ring node segment identifiers (Ring-SIDs) on the ring node, wherein a first of the two Ring-SIDs (CW-Ring-SID) is to reach N in a clockwise direction on the ring and a second of the two Ring-SIDs (AC-Ring-SID) is to reach N in an anti-clockwise direction on the ring, and wherein the CW-Ring-SID and AC-Ring-SID are unique within a source packet routing in networking (SPRING) domain including the ring; (b) generating a message including the ring node's CW-Ring-SID and AC-Ring-SID; and (c) advertising the message, via an interior gateway protocol, for receipt by other ring nodes belonging to the ring such that (1) a clockwise multipoint-to-point path (CWP) is defined such that every other one of the ring nodes belonging to the ring can be an ingress for the CWP and such that only the node is an egress for the CWP, and (2) an anti-clockwise multipoint-to-point path (ACP) is defined such that every other one of the ring nodes belonging to the ring can be an ingress for the ACP and such that only the node is an egress for the ACP.
A computer-implemented method for used by a ring node N belonging to a ring, the computer-implemented method comprising:
A node assigned to a ring comprising a subset of n nodes {Ri, 0<=i<n}, wherein a direction from node Ri to Ri+1 is defined as “clockwise” (CW) and the reverse direction is defined as “anti-clockwise” (AC), the node comprising:
A non-transitory computer-readable medium storing processor executable instructions which, when executed by at least one processor of a ring node N belonging to a ring, cause the at least one processor to perform a method comprising:
