Embodiment Construction

[0022] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] In related technologies, an interface of a network device usually has a packet statistics function to monitor the packet transmission status of the device itself. However, for the packets transmitted on the link, the link itself does not count the packets, especially when a packet loss fault caused by a transient link failure occurs, the existing technology has detection blind spots and the detection effect is not good. In addition, in the prior art, the troubleshooting of link faults cannot be accurately located, and the location of the fault can only be determined by manually checking the link segment by segment.

[0024] In view of the above problems, the embodiment of the presen...

Abstract

The invention discloses a detection method, a detection device and a detection system of message loss, wherein the method comprises the following steps of regulating the period of a receiving end synchronously corresponding to the sending end; reading the total accumulated number of the message sent by the sending end according to the regulated synchronous responding period; reading the total accumulated number of the message received by the receiving end and number of the received message in neighbor two periods according to the regulated synchronous corresponding period; if the number of the received message in the neighbor two periods is less than the preset threshold and the total accumulated number of the message sent by the sending end is not equal to the total accumulated number of the message received by the receiving end, determining that the message loss between the sending end and receiving end exists. According to the technical proposal of the invention, the message loss caused by link faults between the receiving end and sending end can be determined, so that the link faults and fault positions between the receiving end and sending end can be judged effectively, thus improving monitoring capability of the system for lost packet faults.

Description

technical field [0001] The present invention relates to a network system, in particular to a packet loss detection method, device, and system. Background technique [0002] A message is the smallest processing unit in network transmission. Packet loss may occur during network transmission, which refers to the phenomenon that the sending end sends a message, but the receiving end does not receive the corresponding message or receives an error message. Packet loss includes system active packet loss and fault packet loss. The system's active packet loss is mainly caused by network congestion, and the system records the active packet loss. Faulty packet loss is mainly caused by physical line failure, equipment failure, virus attack, routing information error and other failures. Such packet loss cannot be recorded or even detected by the system. [0003] Currently, in related technologies, technologies for detecting packet loss caused by link faults include: packet loss statis...
