Abstract
A method, network element, and network provide detecting a failure on both ports of a major ring at a network element that has an interconnecting sub-ring terminating thereon; causing a block at an associated sub-ring termination port of the interconnecting sub-ring responsive to the failure on both the ports of the major ring; and monitoring the failure and clearing the block responsive to a recovery of one or both ports from the failure. The method, network, and network element include G.8032 multiple concurrent or simultaneous fault recovery mechanisms that traffic being transported between an interconnected major ring and a sub-ring to be successfully delivered in the event of dual concurrent faults on the major ring.
