Loop circuit self-test and self-healing method and device

Abstract

This invention relates to a loop circuit self-test and self-healing method and device, and is applied in the execution of the network communications equipment of a network topology structure. The loop circuit self-test and self-healing method comprises the steps that the first information which can be broadcasted is outputted from a first port according to the set time interval; the second information inputted in a second port is received; the content of the second information and the content of the first information are compared; if the second information includes the set content in the first information, the loop circuit is confirmed to appear in the network topology structure; and the first port or the second port is closed. According to the loop circuit self-test and self-healing method and device, loop circuits can be detected in time, and the loop circuits are promptly destroyed, so that the loop circuits are prevented from continuing running, in order to avoid paralysis in the broadcast storm, or even in an entire network; the negative impact of loop circuits in a network topology can be avoided through using the above loop circuit self-test and self-healing method and device.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for loop self-inspection and self-healing. Background technique [0002] With the development of Internet technology and the increasing complexity of network requirements, the network topology has become increasingly complex. Network communication devices in the network topology, such as switches, may short-circuit two ports of the same switch that should not be connected or between two switches in order to achieve link backup during the wiring construction of the computer room. Thus forming a loop. [0003] Once a loop occurs in the local network, data will be repeatedly transmitted in the network, which will cause a broadcast storm and cause the entire network to be paralyzed. Therefore, how to avoid the negative impact brought by the loop in the network topology is an urgent problem to be solved. Contents of the invention [0004] Based on this, it is...
