Loop detection method, loop detection device, loop detection equipment and computer readable storage medium

Abstract

The invention provides a loop detection method, and the method comprises the steps: transmitting a detection message on at least one equipment port of target equipment if a loop is predicted to exist on the target equipment, so as to detect the loop on the target equipment; if the loop is not detected, making further detection, namely, when the bandwidth utilization rate of at least one equipment port on the target equipment is greater than a first bandwidth threshold and the duration of the phenomenon is greater than a first preset duration, meaning that the packet sending number of detection messages is increased on the at least one equipment port of the target equipment, the invention is used for detecting a loop on target equipment. Visibly, according to the embodiment of the invention, the flow state of the target equipment can be monitored, and when the bandwidth utilization rate of the equipment port is relatively high, the packet sending number of the detection messages can be increased, so that the probability that the detection messages can be received by the target equipment is improved, and a network loop can be discovered timely and effectively.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a loop detection method, device, equipment and computer-readable storage medium. Background technique [0002] In a large-scale LAN network environment, network loops are likely to occur due to improper network device configuration, network device hardware damage, network topology connection errors, and network encountering virus attacks. Network loops will cause network devices to continuously copy and forward broadcast, multicast, and unknown unicast packets, causing network paralysis and affecting normal services. [0003] At present, in order to detect network loops, a network device can actively send a detection message, and when the network device receives the detection message sent by itself, it will recognize that a network loop exists on the network device. However, when a network loop occurs, the traffic in the network may fully occupy the bandwidt...

Problems solved by technology

However, when a network loop occurs, the traffic in the network may fully occupy the bandwidth of the network device. At this time, the loop detection packet may be directly dropped by the network device due to bandwidth problems, resulting in the failure to detect the network loop.
