System and method for setting redundant path segments in a multi-ring communication network

A system for setting redundant path segments in a multi-ring communication network, the system comprising:

• a first plurality of nodes communicably coupled to each other through a first ring included in the multi-ring communication network;
• and
• a second plurality of nodes communicably coupled to each other through a second ring included in the multi-ring communication network, wherein
• the first plurality of nodes includes a first connection node that is adjacently connected to a second connection node included in the second plurality of nodes;
• and
• the first connection node is configured to:
• receive traffic information from adjacent nods including the second connection node and a pair of nodes that are located adjacent to the first connection node along the first ring, the traffic information storing a pair of input and output node identifiers in association with each of storage areas included in a frame to be transmitted in the multi-ring communication network, the input node identifier identifying an adjacent node from which first data stored in the each of storage areas is inputted, the output node identifier identifying an adjacent node to which the first data stored in the each of storage areas is outputted, and
• set a plurality of redundant path segments each including the second connection node, based on the received traffic information, when the received traffic information includes the output node identifier identifying the second connection node, the plurality of redundant path segments including a currently-used path segment.
