Embodiment Construction

[0042] In order to solve the problem that the existing link detection technology cannot accurately detect the cause of the link failure. The invention provides a link detection method, device and system.

[0043] Such as figure 2 As shown, the link detection method provided by the embodiment of the present invention includes:

[0044] 201. It is detected that the current link is faulty;

[0045] 202. Send the LB cell to the sender;

[0046] 203. Determine where the current link fault occurs according to whether the LB response cell returned by the sender is received.

[0047] According to the regulations of ATM network on LB function, after receiving LB cell, the sending end will respond to the receiving end by sending LB response cell; moreover, the process of responding to LB cell is not very In the starting state, the response process can be completed and the LB response cell is sent out. Therefore, the above-mentioned characteristics of the LB function can be used to...

Abstract

An embodiment of the invention discloses a link detection method, a device and a system which relate to the communication technique field. The method, the device and the system are invented for solving problem that the prior art can not determine link fault accurately. The method includes: detecting fault of the present link; sending a ring reply cell to a sending end; judging the fault position of the present link according with whether receiving the ring reply response cell returned by the sending end. The embodiment can find fault reason more accurately when the link occurs fault that creates condition for preparing fault timely and ensures reliable running of the network efficiently.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a link detection method, device and system. Background technique [0002] With the development of communication technology, the scale of communication network is getting larger and larger, which adds difficulty to the maintenance of communication network. Quickly querying and troubleshooting network faults is an important prerequisite for ensuring reliable network operation. [0003] The existing ATM (Asynchronous Transfer Mode, asynchronous transfer mode) network performs continuity detection on the link through the CC (Continuity Check, continuous detection) function in its maintenance mechanism. If the link is normal, it will allocate Corresponding business; once a problem is found, immediately report a link abnormality alarm so that measures can be taken to repair it. [0004] The CC feature works like figure 1 Shown: The sending end sends CC cells to the rec...
