In the existing network, for the detection of network failure, some links usually detect the link failure by means of hardware detection signals, for example, using SDH (Synchronous Digital Hierarchy) alarm, but in practical cases, not all media can provide hardware detection, and some applications rely on the Hello message mechanism of the upper layer protocol to perform failure detection, but the detection time of the upper layer protocol is more than 1 second, such failure detection time is too long for some applications, and meanwhile, in some small three-layer networks, if no routing protocol is deployed, the Hello message mechanism of the routing protocol cannot be used to detect the failure. The BFD protocol is generated under the background, the BFD can realize rapid detection, simultaneously monitor the forwarding communication state of a link or an IP route in a network, improve the network performance, discover communication faults between adjacent systems through rapid detection, and can help a user to establish a backup channel to recover communication more quickly, thereby ensuring the reliability of the network. The bfd (bidirectional Forwarding detection) protocol is a network protocol for detecting faults between two Forwarding points.
