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 ...

Abstract

The invention discloses a method and a device for detecting a wireless link fault. The method comprises the steps of sending detection messages in a preset number to a fault server by a sending end router every preset time; determining the number of response messages received and returned by the fault server within the preset time, wherein the response messages are messages which are sent to the sending end router by the fault server by taking a specific value as a period after the specific value between the preset time carried in the detection messages and the number of fault judging messages is determined, and the preset number is smaller than the number of the fault judging messages; determining that a wireless link is in failure when the situation that the response messages returned by the fault server are not received within the preset time is determined; determining that the wireless link is not in failure when the situation that at least one response message returned by the fault server is received within the preset time is determined. By adopting the scheme provided by the embodiment of the invention, compared with the prior art, the message traffic for wireless link fault detection is reduced, and the traffic consumption is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for detecting a wireless link failure. Background technique [0002] With the rapid development of wireless networks, various data can be transmitted through wireless links. Once a wireless link fails, data transmission will be interrupted. Therefore, testing wireless links is a prerequisite to ensure smooth network. [0003] The existing wireless link fault detection methods mainly include the following two types: [0004] A. BFD fault detection: The sending router sends a Bidirectional Forwarding Detection (BFD, Bidirectional Forwarding Detection) detection packet to the receiving router, and when the receiving router receives the BFD detection packet, it returns a response packet to the sending router. When the number of BFD detection packets received by the router at the receiving end within a preset time period is less than the preset numbe...
