摘要： A communication network system having at least three nodes, which are interconnected by transmission links carrying traffic to and from the nodes. The transmission links are divided into a working ring and a protection ring where the working ring and the protection ring can transmit traffic in opposite directions. A node is able to detect when an error occurs in the surrounding transmission links or the node itself. Each node can, by itself, divert traffic from the working ring to the protection ring and/or from the protection ring to the working ring. A recovery action is performed when the error is healed.
