example

[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. ...

Abstract

The invention provides a method for optimizing a path on an Ethernet ring protection switching ring. The method comprises the following steps: the optimization function of EPRS is triggered by carrying link quality attributes in a sent message (NR, RB) so as to confirm a link with the poorest quality, and a blocked link in an ERPS ring network is switched to the confirmed link with the poorest quality. On the basis of the same conception of the method provided by the invention, the application further provides a device for optimizing the path on the Ethernet ring protection switching ring, so that the use ratio of the bandwidth of the ERPS ring network can be increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an Ethernet ring protection switching ring path optimization method and device. Background technique [0002] Ethernet is currently the most widely used LAN technology, it has the characteristics of simplicity, economy and high data rate. In recent years, it has rapidly developed to wide area network and metropolitan area network technology. Carrier-grade Ethernet requires the network self-healing time to be within 50ms. Therefore, how to improve the reliability of Ethernet technology has become the focus of attention. Many Ethernet ring network ring protection technologies have appeared successively. In March 2008, ITUT-T released the G.8032 protocol. It absorbs the advantages of other protocols and provides high reliability services for Layer 2 Ethernet networks, becoming an international standard. [0003] When the Ethernet Ring Protection Switching (Ethernet...
