Abstract

The embodiment of the invention relates to the technical field of communication, and especially relates to a fault detection method and device, so as to alleviate the network load, and reduce the network cost. In the embodiment of the invention, the method comprises the steps: determining the frequency that first equipment transmits a fault detection message when all user equipment corresponding to the first and second equipment does not build business connection; adjusting the frequency that the first equipment transmits the fault detection message when the frequency that the first equipment transmits the fault detection message is determined to be not less than a first threshold value, so as to enable the adjusted frequency that the first equipment transmits the fault detection message to be less than the first threshold value; and / or determining the frequency that the second equipment transmits the fault detection message; adjusting the frequency that the second equipment transmits the fault detection message when the frequency that the second equipment transmits the fault detection message is determined to be not less than a second threshold value, so as to enable the adjusted frequency that the second equipment transmits the fault detection message to be less than the second threshold value.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a fault detection method and device. Background technique [0002] In the field of communication, in order to ensure the quality of data transmission between network devices, it is necessary to quickly detect communication failures between network devices, so as to establish a new communication link in time when a failure occurs, or switch to other communication links. . At present, a bidirectional fault detection (Bidirectional Forwarding Detection, BFD for short) method is a most widely used network fault detection technology. The characteristics of BFD are: light load, short duration, and it can quickly implement any type of communication link, such as direct physical link, virtual circuit, multi-hop routing channel, etc. [0003] After a BFD session is established, both parties in the BFD session periodically send BFD packets to the peer end on the s...
