Specifically, the client device may first calculate a time interval between a reception time of the ICMP response message and a transmission time of the ICMP request message; and taking the time interval as the delay time of the remote server; availability of a remote service provided by the remote server is then detected based on the delay time of the remote server. Further, if the delay time of the remote server is less than a preset duration threshold, the client device may determine that the remote service provided by the remote server is available; if the delay time of the remote server is greater than or equal to the duration threshold, the client device may determine that the remote service provided by the remote server is unavailable.
And S104, if the remote service provided by the remote server is unavailable, switching the network state from the online state to the offline state.
In this step, if the remote service provided by the remote server is not available, the client device may switch its network state from the online state to the offline state. Specifically, the client device can be automatically switched to the ideal state under the condition that the network condition of the client device is not good or the remote service is unavailable, so that the waiting time of a user can be reduced, and the traffic loss is avoided.
The network state switching method provided by the embodiment of the application comprises the steps of firstly sending an ICMP request message to a remote server through a PING command; recording the sending time of the ICMP request message; then receiving an ICMP response message corresponding to the ICMP request message returned by the remote server; recording the receiving time of ICMP response message; then, based on the sending time of the ICMP request message and the receiving time of the ICMP response message, the availability of the remote service provided by the remote server is detected; and if the remote service provided by the remote server is unavailable, switching the network state of the remote server from the online state to the offline state. That is, the present application can automatically switch its network status from an online status to an offline status by detecting the availability of a remote service provided by a remote server. In the prior art, when the network status of the client device is not good or the remote service is unavailable, the user usually accesses a large and stable third-party website at regular time to determine whether the network of the client device is connected or whether the remote service is available. The availability of the remote service provided by the remote server is detected by sending an ICMP request message and receiving an ICMP response message; if the remote service provided by the remote server is unavailable, the technical means for automatically switching the network state of the remote server from the online state to the offline state overcomes the technical problem that the traffic loss is caused by request failure such as overtime and the like if the client continuously sends an online request under the condition that the network state of the client equipment is poor or the remote service is unavailable; moreover, the technical scheme of the embodiment of the application is simple and convenient to implement, convenient to popularize and wide in application range.
