Embodiment 1

[0048] Such as figure 1 Shown is a flow chart of a link detection method based on OAM in an embodiment of the present invention, and the method includes the following steps:

[0049] Step 101 , the first OAM detection device used for link state detection receives a first OAM management message sent by the second OAM detection device used for link state detection at the opposite end.

[0050] First of all, it should be explained that the specific solution in this embodiment of the present invention is applied to the OAM link detection technology. When performing link detection, the first OAM detection device and the second OAM detection device will periodically send The packets are detected, and then the first OAM detection device and the second OAM detection device determine whether the link is abnormal according to the number of received packets.

[0051] In the prior art, if the second OAM detection device or the OAM detection module in the second OAM detection device is re...

Embodiment 2

[0078] The methods in Embodiment 1 and Embodiment 2 are described below through the flow chart of information interaction in the system formed by the first OAM detection device and the second OAM device:

[0079] Such as figure 2 Shown is the information interaction process in the system formed by the first OAM detection device and the second OAM detection device, which specifically includes the following process:

[0080] Step 201, the detection function of the second OAM detection device is abnormal;

[0081] Step 202, the second OAM detection device sends the first OAM management message carrying detection status information, restart time information, and packet loss count information to the first OAM detection device;

[0082] Step 203, the first OAM detection device closes its own link detection function according to the detection status information in the first OAM management message, and saves the time value and packet loss count information in the restart time inform...

Embodiment 3

[0089] Corresponding to the method in Embodiment 1 of the present invention, the embodiment of the present invention also provides a link detection device based on OAM, such as image 3 Shown is a link detection device based on OAM in the embodiment of the present invention, the device includes:

[0090] The receiving module 301 is configured to receive the first OAM management message sent by the OAM link detection device at the opposite end of the OAM link detection device for link state detection;

[0091] A processing module 302, connected to the receiving module 301, configured to close the OAM link when the first OAM management message carries information indicating that the peer OAM link detection device is in an abnormal state Check the link detection function of the device.

[0092] Such as Figure 4 As shown, the device also includes:

[0093] The detection module 401, connected to the receiving module 301, is used to determine the time value used to represent the...

Abstract

The present invention provides a method and equipment for operation, management and maintenance OAM link detection, the method includes: the first OAM detection device used for link state detection receives the second OAM detection device used by the peer end for link state detection After the first OAM management message is sent, when the first OAM management message carries information indicating that the second OAM detection device is in an abnormal state, the first OAM detection device will close its own link detection function, thereby avoiding An abnormality of the OAM detection equipment at one end causes the problem that the OAM detection equipment at the opposite end incorrectly issues a link failure alarm, thereby improving the accuracy of link detection by the OAM detection equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a link detection method and equipment based on OAM (operation Administration and Maintenance). Background technique [0002] Currently, in the IP bearer network, the OAM technology for operation management and maintenance has been widely used and deployed. It is mainly used to detect the link quality and service quality of the operator network. When the monitored link connectivity fails, the OAM technology The failure time can be notified in time to the network administrator in the form of an alarm. [0003] Specifically, in the prior art, the OAM detection devices on both sides of the monitored link periodically send and receive detection packets, and if no detection packets have been received within 3 or 3.5 detection cycles, it is judged to be The monitoring link has failed, and the fault information is notified to the network administrator in the form of an al...
