The application provides a bidirectional fault detection method, system, device and readable storage medium, the method comprises the following steps: determining whether the received message is a BFD control message based on the access control list rule issued by the central processor; if the received message is a BFD control message, the BFD control message is sent to the hardware operation management maintenance engine, and the BFD session information corresponding to the BFD control message is acquired based on the hardware operation management maintenance engine to detect the connectivity of the BFD control message; if the received message is not a BFD control message, the received message is sent to the central processor. Compared with the prior art, the application avoids excessive consumption of CPU resources caused by the increase in the number of BFD sessions or the shortening of the detection period. On the other hand, the hardware processing of the BFD service eliminates the uncertainty factors on the software processing path, can realize better timing accuracy, and improves the reliability of detection and the network convergence speed.
