Embodiment Construction

[0022] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] The present invention provides a method for reporting that the fault disappears, referring to figure 1 , the method includes the following steps:

[0024] Step A, record the link state as connected, and configure the watchdog to report the alarm generated by the fault directly if the operation, management and maintenance OAM message is not received within a period T; for example, the sending speed of the OAM message It is 3.3ms / packet. According to the OAM protocol, the detection period T is three times the speed of sending OAM packets, that is, 10ms. If the link does not receive an OAM message within 10 ms, it is judged that the link has failed, and the watchdog reports that the fault occurs. After the fault occurs, the configuration module saves the link and its state association after receiving the alarm. ...

Abstract

Disclosed is a method for reporting fault generation and disappearance, comprising: A. recording a state of a link to be on, and at the same time, configuring a watchdog to directly report an alarm of fault generation if an operation administration and management (OAM) message is not received within a period T; B. determining whether the watchdog detects fault generation of the link; C. when the watchdog detects fault generation of the link, changing a current state of the link to be off, and at the same time, reconfiguring the watchdog, configuring a fault disappearance detection period of the watchdog to be n*T, and if the number of received packets of the link in a detection period is larger than a preset threshold, reporting an alarm of fault disappearance, n being an integer larger than 1; and D. determining whether the watchdog reports the alarm of fault disappearance, and returning to step A when the watchdog reports the alarm of fault disappearance. Further provided is a device for reporting fault generation and disappearance. In this technical solution, the operation process is simple and the development and maintenance are very convenient.

Description

technical field [0001] The present invention relates to the application field of network technology, and more specifically, to a method and device for reporting fault generation and disappearance. Background technique [0002] In order to improve the security and reliability of the network, the current network adopts the protection mechanism of OAM (Operation Administration and Maintenance), and uses the backup link to protect the working link to minimize the failure of the link. Data loss caused by network users improves network security and reliability. [0003] The working principle of the OAM protection mechanism is as follows: run OAM detection on the working link. When the working link fails, the detection mechanism will quickly alarm and switch the service flow to the standby link; Switch back to the working link. To minimize the loss of service flow, the key is to speed up the switching speed, and the key to the switching speed is the alarm speed. Therefore, the a...
