Problems solved by technology

[0005] When using the ping command to detect the status of the network link, only the link status between the local device and the peer device can be obtained. To detect the status of multiple network links, the ping command needs to be used multiple times, thus, Resulting in less efficient link fault detection

Embodiment Construction

[0213] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0214] An embodiment of the present invention provides a method for link fault detection, which can be implemented jointly by a first device and a second device, where the first device and the second device can be any device in a local area network, such as a PC (Personal Computer, personal computer), the first device and the second device belong to the same local area network (also including a virtual local area network that can communicate between devices), and can communicate with each other.

[0215] The link detection sending end and the link detection receiving end can be set in the devices that can communicate with each other in advance. Among them, the second device can be set as the link detection sending end, and other devices...

Abstract

The invention discloses a method, apparatus and system of detecting a link fault, and belongs to the field of the Internet technology. The method of detecting a link fault includes the steps: in the state that first equipment is used as a link detection receiving end, according to a preset detection cycle, detecting a link detection message transmitted from second equipment which is taken as a link detection transmitting end in a multicast mode; and when detecting that the quantity of packet loss of the link detection message reaches a first preset threshold, determining that a link fault exists between the first equipment and the second equipment. The method, apparatus and system of detecting a link fault can improve the efficiency of improving link fault detection.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method, device and system for link fault detection. Background technique [0002] In the existing network networking model, the data packet will pass through multiple devices in the network link to reach the receiving end. If any device or line in the network link fails, the data packet will not reach the receiving end. Therefore, detecting link failure becomes particularly important. [0003] At present, the method for detecting link failure is often to use the ping command, which needs to input the ping command and the IP (Internet Protocol, Internet Protocol) address of the peer device, and then can detect the link between the local device and the peer device. state. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] When using the ping command to detect the status o...
