Embodiment Construction

[0043] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0044] figure 1 It is a data structure schematic diagram of the Ethernet loopcheck software module, and the present invention is based on the data structure of the loopcheck software module of the existing Ethernet switch, such as figure 1 Shown is the data structure of the loopcheck software module. The loopcheck software module adopts an array as the main data structure. First define the global structure type pointer gpNlcInfo, the main function of this pointer is to identify the first address of the array. In the data structure related to the port, each member of the array stores information such as the port information, the loopcheck status of the port, and the result. Specifically, pPortInfo[0] stores various loopcheck information corresponding to the port whose port number is 1, pPortInfo[1] stor...

Abstract

The invention discloses a method for positioning an Ethernet loop. The method comprises the following steps of: A, finding the loop in a loopcheck software module; B, processing when a port receives a loopcheck explorer frame; and C, when determining that the loop exists in a network, isolating the port where the loop is. A network logical entity uses the method for positioning the Ethernet loop, such as network nodes of a transparent network bridge, an Ethernet switch or a router; and when the loop or a broadcast storm caused by the loop occurs, a network looping failure can be removed by the method and loop points are positioned by adopting corresponding measures, so that the range which the broadcast storm is spread to can be controlled and the efficiency of network maintenance can be greatly improved.

Description

technical field [0001] The invention relates to network communication technology, in particular to an Ethernet loop positioning method. Background technique [0002] In the Ethernet application environment, network loops are often caused by unknown reasons. Due to the common channel characteristics of Ethernet, the looped network will cause network broadcast storms, which will affect network services. Therefore, Ethernet loops should be avoided as much as possible. road phenomenon. [0003] At present, when a user on the access side surfs the Internet, he sometimes suddenly feels a large delay or drops out suddenly. This phenomenon is probably caused by a loop in the access network connected to his computer. Because the network on the access side is close to users, its network topology will change from time to time according to user needs, and the stability of the network topology directly affects the stability of user experience. In addition, the network loop may not be c...
