Problems solved by technology
[0006] However, at present, there is only an effective ring network protection mechanism for a single Ethernet ring network. For any topology where multiple Ethernet ring networks intersect, there is no effective ring network protection mechanism to ensure the smoothness of the ring network links and avoid loops

Embodiment Construction
[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0054] The present invention proposes a method for protecting an intersecting ring network of any topology. The method is applied to an intersecting ring network of any topology formed by the intersection of multiple Ethernet ring networks. Each Ethernet ring network includes a master node and several transmission nodes. The master nodes of each Ethernet ring network in the ring network are configured with respective priorities, and the method includes: the master node in the Ethernet ring network detects whether a polling error occurs, and if so, sends a message carrying its own priority and The identified polling error message, and monitor whether it receives the polling error message carrying its priority and identification sent by othe...

The present invention discloses a method for protecting an arbitrary topological intersecting ring network, the master node of each Ethernet ring in the intersecting ring network is allocated with a respective priority, and the method comprises the following steps: the master node of each Ethernet ring detects whether a polling error happens, if so, the polling error message with own priority and identification is sent by the intersecting ring network; and the master node also detects whether the polling error message with own priority and identification from other master nodes is received in a predetermined time length, if so, whether the own priority is the highest is judged according to the priority and identification carried by the received polling error message and the own priority, if so, a secondary port is opened. The present invention also discloses a master node and an intersecting ring network. The present invention can provide an effective ring network protection system for a plurality of arbitrary topological intersecting Ethernet ring networks.
Description
technical field [0001] The invention relates to the technology of the Ethernet ring network, in particular to a method for protecting an intersecting ring network of any topology, a node and an intersecting ring network. Background technique [0002] At present, the Ethernet ring network is gradually popularized and applied. figure 1 It is a schematic diagram of the structure of a single Ethernet ring network. see figure 1 , in a single Ethernet ring network, including a master node and multiple transmission nodes, the master node and each transmission node transmit business data on the Ethernet ring network to complete various business functions. [0003] Since the Ethernet ring network is a ring network structure, it is necessary to prevent loops, so as to avoid broadcast storms caused by unknown unicasts and broadcasts being circulated on the ring. At present, for a single Ethernet ring network, there are relatively mature technologies to avoid loops and ensure data tr...
