Embodiment Construction

[0037] In order to make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and the description thereof are used to explain the present invention, but not as a limitation to the present invention.

[0038] The embodiment of the present invention solves the problem of broadcast storm in the EAPs ring network due to equipment response delay when the link is restored by forcibly forwarding the detection message and canceling the up message in the existing EAPs protocol when the link is restored:

[0039] (1) Force forwarding of probe messages

[0040] When the link between the transmission switch D and the transmission switch C fails, the Master will not be able to receive the detection message sent by itself on the slave port; Picture 11 As shown, when the link between ...

Abstract

The invention provides a method for preventing broadcast storm in an Ethernet ring network, and transmission switches for the Ethernet ring network. The method comprises the following step: a transmission switch at each end of a link forcedly forwards a detection message captured from one interface of the transmission switch to the other interface of the transmission switch when the link is restored. The method can avoid the occurrence of broadcast storm due to response lag of equipment when the link is resorted, so as to improve the stability of the Ethernet ring network.

Description

Technical field [0001] The present invention relates to Ethernet technology, in particular to a method for improving the stability of an Ethernet ring network, and in particular to a method for preventing broadcast storms in an Ethernet ring network and an Ethernet ring network transmission switch. Background technique [0002] With the rapid development of Ethernet technology and the continuous improvement of applications, it has become an unstoppable trend to use cost-effective Ethernet technology to build large-scale enterprise networks and metropolitan area networks. In this type of network environment with large scale and multiple services, most of them deploy ring topologies, such as figure 1 As shown, the characteristic of the ring topology is that each device uses two ports to interconnect with adjacent devices to form a closed link. [0003] If an Ethernet switch is used to construct this ring topology, we call it an Ethernet ring network. In an Ethernet ring network, t...
