Problems solved by technology

However, these two processing methods have the following disadvantages: the replacement of hardware will increase the hardware cost, and the improvement of the Icmp Echo Reply message processing priority level on the software will affect the normal processing of other messages. The business burden of the PING initiating device cannot be reduced, and the detection accuracy reduction caused by the delayed processing or discarding of some packets by the PING initiating device cannot be avoided.

Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] figure 2 is a flowchart of a network detection method according to an embodiment of the present invention, such as figure 2 As shown, the method mainly includes the following steps (step S202-step S206):

[0027] Step S202, the device under test receives a detection message carrying a preset allowable delay time sent by an Internet connectivity detector (PING) initiating device;

[0028] Step S204, the device under test determines the actual delay time for sending a response message corresponding to the detection message to the PING initiating device according to the allowable delay time;

[0029] In the embodiment of the present invention, preferably, the device under test may randomly s...

Abstract

Disclosed are a network detection method, device, and system. The method comprises: an apparatus to be detected receiving a detection packet carrying a preset allowable delay time and sent by a Packet Internet Groper (PING) initiation apparatus; the apparatus to be detected determining, according to the allowable delay time, an actual delay time after which a reply packet corresponding to the detection packet should be sent to the PING initiation apparatus; when the actual delay time is reached, the apparatus to be detected sending a reply packet carrying the actual delay time to the PING initiation apparatus. By means of the present invention, the precision of the network detection can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network detection method, device and system. Background technique [0002] In the field of network communication, PING (Packet Internet Groper, Internet Connectivity Detector) technology is the most common method for detecting connectivity between devices. PING initiates the Icmp Echo sent by the device through its IP (Internet Protocol, Internet Protocol) address. Whether the Request (Internet Control Information Protocol Request) message and the target device have responded to the Icmp Echo Reply (Internet Control Information Protocol Reply) message determines whether the target device can be reached, and sends the Icmp Echo Request message and receives the Icmp Echo Reply message through calculation. The time difference of the text is used to obtain the network communication delay between devices. [0003] Please refer to figure 1 ,Such as figure 1 As shown, in the proce...
