Abstract

The present disclosure provides a bidirectional forwarding detection method, device, electronic equipment, and readable storage medium, wherein the bidirectional forwarding detection method includes: switching the BFD session state if the ready state message sent by the peer device is obtained It is the established state; control the main hardware single board and the standby hardware single board to alternately send established state messages to the peer device. This method enables the peer device to receive the UP message within a predetermined time by intelligently and dynamically adjusting parameters to send a message, which avoids that when the main hardware single board is not in place, the CPU single board controller cannot receive the UP message within the predetermined time. Sensing that the main hardware board is no longer in place, there is no way to send a message to the standby hardware board to upgrade to the main hardware board. As a result, the standby hardware board cannot send an UP message within the preset time, and the peer end The device does not receive the UP packet within the predetermined time, so the peer device causes the BFD protocol to go down due to timeout.

Description

technical field [0001] The present disclosure relates to the technical field of data communication, and in particular to a bidirectional forwarding detection method, device, electronic equipment and a readable storage medium. Background technique [0002] BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection) is a general, standardized, medium-independent and protocol-independent fast fault detection mechanism, which is used to detect the connectivity of links in IP networks and ensure that communication between devices can be quickly detected faults, so that measures can be taken in time to ensure the continuous operation of the business. [0003] In current distributed high-end routers, BFD UP packets are sent by the CPU, which is called software BFD; BFD UP packets are sent by hardware, which is called hardware BFD; hardware BFD usually consists of a maintenance board and a backup maintenance board. The maintenance board is a hardware board responsi...
