Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as there is no conflict with each other.

[0028] In view of the existing problems in the prior art, in order to minimize the impact of loop failures, it is necessary to find a way to let each node know the topology of the entire network. Whether you are involved in the generation of the loop, and whether you need to take measures to block the loop.

[0029] In order to achieve the above purpose, such as figure 1 As shown, the present inve...

Abstract

The invention discloses an Ethernet looped network breaking method, which comprises the following steps: when network nodes change, enabling each node in the network to know the topology of the whole network through topology learning; and when the network data flow is abnormal, judging whether a loop is generated or not, and if the loop is generated, carrying out looped network damage. According to the invention, each node knows the topology of the whole network at ordinary times and also knows the position of the node in the network, a certain node can immediately know the position where the loop is generated and the newly added port when the looped network appears, the looped network can be broken only by disconnecting the newly added port of the node, the looped network breaking speed is high, and the stability is high. When the network is stable at ordinary times, additional messages do not need to be sent, and basically no load exists. The invention further provides a ring network breaking system of the Ethernet, the ring network breaking system comprises a plurality of nodes, and ring network breaking is carried out by adopting the ring network breaking method of the Ethernet when the network data flow is abnormal.

Description

technical field [0001] The invention belongs to the technical field of communication, and more particularly, relates to a method and system for breaking a ring network of an Ethernet. Background technique [0002] Incorrect Ethernet connection or incorrect configuration of network devices may lead to a loop in the Ethernet. This loop will cause a broadcast storm, resulting in a large number of broadcast packets in the network, seriously affecting the operation of the entire network. Traditionally, each node does not know the network situation, but only knows that a large number of packets cause its own resources to be exhausted. It cannot judge where the packets come from or whether it is a broadcast storm. SUMMARY OF THE INVENTION [0003] The technical problem to be solved: In the network, each node does not know its own topology, and when receiving a large amount of data, it cannot judge whether a loop is formed and a broadcast storm is caused. In order to reduce the i...
