<p>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.</p> |
