[0080] see image 3 , image 3 This is a schematic diagram of a single-instance ERPS ring network. image 3 Among them, Node A, Node B, Node C, and Node D form the main ring, and Node C, Node D, Node E, and Node F form the sub-ring. Both the main ring and the sub-ring are configured with single instance 1, and Node A is on the main ring. The master node, node B is the neighbor node on the master ring, the link between node A and node B is an RPL link, port P1 of node A and port P1 of node B are blocked ports on the RPL link; node E is the master node on the subring, node F is the neighbor node on the subring, the link between node E and node F is an RPL link, and port P2 on node E and port P2 on node F are RPL blocked ports. The bandwidth of each link in the ERPS ring network is as follows: image 3 As shown in , configure the instance priority of instance 1 to be 0.
[0081] The method of optimizing the path of the ERPS ring in the sub-ring and the main ring is the same. ...
