Connecting state detection method and related equipment

The present application provides a connection state detection method and related equipment. The method includes: collecting source node information and generating a detection list, which includes a source node of each host, a plurality of network interfaces and a plurality of target nodes of each source node, each of the network interfaces corresponding to one target node; selecting a source node to be detected; sending a network detection request to the source node to be detected, controlling the source node to be detected to detect a connection state between the source node and the target node, and obtaining a detection result; determining a cause of a failed connection based on the detection result and the detection list. The present application can modify the detection list automatically without human interaction, and can quickly converge the cause of the failed connection.
