Embodiment 1
[0068] In the embodiment of the present invention, the process of the wireless link fault detection method is described by taking the message interaction between the router at the sending end and the faulty server as an example, image 3 The flow chart of the wireless link fault detection method provided by the embodiment of the present invention specifically includes the following processing steps:
[0069] Step 301, the router at the sending end sends a preset number of detection packets to the faulty server every first preset time interval.
[0070] Wherein, the detection message may carry a first preset duration Tt, a number N of fault judgment messages, and a magic number mark. The preset number is smaller than the number of fault judgment messages, for example, the preset number may be 2. The size of the probe message is 64 bytes.
[0071] Since the size of the detection message sent in the prior art is not configurable, and the size of the message is fixed at 120 byte...
Embodiment 2
[0091] Based on the same inventive concept, according to the wireless link fault detection method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 2 of the present invention also provides a wireless link fault detection device, the structural diagram of which is as follows Figure 4 shown, including:
[0092] A sending unit 401, configured to send a preset number of detection messages to the faulty server every preset period of time;
[0093] The first determining unit 402 is configured to determine the number of response messages returned by the faulty server received within the preset time length, the response messages being carried by the faulty server in determining the detection message After the preset time length and the ratio of the number of fault judgment messages, send the message to the router at the sending end according to the ratio according to the period, and the preset number is less than the number of fault jud...
Embodiment 3
[0101] Based on the same inventive concept, according to the wireless link fault detection method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides a wireless link fault detection device, the structural diagram of which is as follows Figure 5 shown, including:
[0102] A receiving unit 501, configured to receive a probe message sent by the router at the sending end;
[0103] The first determining unit 502 is configured to determine whether the detection message carries a magic number mark;
[0104] The second determination unit 503 is configured to determine the ratio of the first preset duration carried in the detection message to the number of fault judgment messages when the detection message carries a magic number mark, and the detection message is A preset number of messages sent by the sender server within a preset time period, the preset number being less than the number of fault ...
