摘要： A method for reconfiguring a ring of nodes connected by a working fiber and a protection fiber upon disruption of the signal in either the working fiber or the protection fiber includes signaling the other nodes. Each node determines whether it is a node adjacent to the disruption. Those nodes that are not adjacent to the disruption undergo no change in their operation. A receiving node adjacent to the disruption forms a bridge isolating the disruption and sends an acknowledgement signal back to a signaling node. Upon receipt of the acknowledgement signal, the signaling node also forms a bridge. This results in the isolation of that portion of the ring having a disruption and the formation of a new ring.
