Embodiment Construction
[0029] In order to achieve the purpose of the present invention, the core idea adopted by the present invention is: in the case that there are multiple communication links between the sending device and the receiving device at the opposite end, the sending device regularly sends the detection message according to the preset first cycle, and The detection message is copied to all links communicating with the receiving device at the opposite end and sent simultaneously; the receiving device at the opposite end counts the number of detection messages received on each link according to the preset second cycle, and At the end of the second period, the number of detection packets received on each communication link is summarized; the peer receiving device judges whether the number of detection packets on each link counted in the detection cycle is greater than the set threshold Ccmp , if yes, it is judged that the link status is normal, otherwise, it is judged that the communication ...
