Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The core idea of ​​the present invention is: on the basis that a single ring network can be quickly and automatically protected, configure and improve each node device on the ring network, and set a single ring as the virtual master node of other ring networks, so as to inherit the original single ring The various advantages of the ring network protection protocol can quickly and simply detect and recover the intersecting ring network faults, and obtain an easily expandable hierarchical network. When two ring networks intersect, there will be two node devices connecting the two ring networks. For convenience of description, they are called the first edge node and the second edge node, and the two intersecting ring networks ...

Abstract

The invention relates to a method for protecting crossed Ethernet network, wherein said network is arranged with quick annular network protective region; said region comprises a main ring and a sub ring; main ring is the virtual main node of sub ring; the main ring via the first and second edge nodes is crossed with sub ring; the port of first edge node connected to the sub ring is the first port of virtual main node; the port of second edge node connected to the sub ring is the second port of virtual main node. And said method comprises following steps: setting the second port of virtual main node as transfer mode; the first port of virtual main node is block mode; checking if the sub ring has chain accidence; if it is, setting the first port of virtual main node as transfer mode, and initializing the refresh transfer list information; when the accidence of sub ring is recovered, setting the first port of virtual main node as block mode, to initialize the refresh transfer list.

Description

technical field [0001] The invention relates to the technical field of network data transmission, in particular to an intersecting Ethernet ring network, an automatic protection method thereof, and ring network node equipment. Background technique [0002] With the gradual popularization and application of the Ethernet ring network, users have higher and higher demands on the performance and scale of the Ethernet ring network. In the current application of the Ethernet ring network, the performance and scale provided by the Spanning Tree Protocol (STP (Spanning Tree Protocol) family) can no longer meet the requirements of the Ethernet ring network. STP (Spanning Tree Protocol) can provide path redundancy, and using STP can make only one effective path between two terminals. STP defines a tree in a large network and forces certain backup paths to be in standby. If part of the network in the spanning tree is unreachable, or the STP path cost value changes, the spanning tree ...
