For example, the server S1 is a first server, the server S2, the server S3, the server S4, and the server S5 are second servers, and the server S1 stores identification information of the server S2, the server S3, the server S4, and the server S5 (for example, the IP of the server S2, the server S3, the server S4, and the server S5). The server S1 issues a first command to the server S2, the server S3, the server S4, and the server S5, and the server S2, the server S3, the server S4, and the server S5 execute the first command after receiving the first command. Assuming that the server S2 finds that the server S3 cannot be connected and the server S4 and the server S5 can be connected through detection, the server S2 sends the command execution result to the server S1, and the server S1 knows that the server S2 and the server S3 cannot be connected after receiving the command execution result.

And if the first step judges that the second server can not be communicated with the first server, determining that the second server network can not be communicated. And if the second server can be communicated with the first server in the step one, executing the step two. Step two: and judging whether the second server can be communicated with other second servers. And if the second server can be communicated with other servers in the second step, determining that the second server network is in a communication state.

The first server stores the identification information of all the second servers in advance. If a certain second server does not send own identification information to the first server, it can be determined that the second server network cannot be connected.
