Problems solved by technology

[0009] This has a problem in practical applications. With a uniform fixed detection time interval, it is impossible to make a more accurate fault judgment according to the requirements of different application types of telecommunication services.
Adopting a single judgment method for all applications makes the fault judgment results of different applications biased
For example, different applications have different requirements for interruption time and detection speed. For example, the interruption time of voice data flow cannot exceed 200ms, and the signaling requirement cannot exceed 500ms. However, the real-time requirements of data services are not as high as voice, but a unified setting A detection interval such as 300ms will not be applicable to different application types; and may cause corresponding misjudgments

example 1

[0092] Example 1: If the preset failure judgment value of the voice service is a single threshold of 0.2; the comparison module 203 compares the characteristic value ψ obtained by the calculation module 202 with 0.2; if the comparison result is that the characteristic value is greater than or equal to 0.2, the judgment module 204 judges the first An application fails, and if the comparison result shows that the characteristic value is less than 0.2, the determination module 204 determines that the voice service application does not fail or does not respond.

[0093] Optionally, the device 200 may also include a fault processing module 205 . Correspondingly, if the judging module 204 judges that a fault has occurred in the voice service, the fault processing module 205 in the device 200 will execute the fault handling measures corresponding to the voice service, so that the voice service can run normally; After returning to normal, the judging module 204 judges that there is no...

example 2

[0094] Example 2: If the preset fault judgment value of the picture transmission service is four value intervals, (0, 3] indicates that the picture transmission service has no failure; (3, 5] indicates that the picture transmission service has a first-level failure; ( 5, 10] indicates that a second-level failure occurs in the picture transmission service; (10, +∞) indicates that a third-level failure occurs in the picture transmission service. The first-level failure, the second-level failure, and the third-level failure correspond to the first-level failure handling measures and the second-level failure respectively. Handling measures, three-level fault handling measures; the comparison module 203 compares the characteristic value ψ with the above-mentioned at least two threshold intervals, and determines the interval where the characteristic value is located; the judgment module 204 judges the failure of the picture transmission service according to the value interval where ψ ...

Abstract

The embodiment of the invention provides a BFD detection method, a device and a system. The BFD detection method comprises steps of: when a first virtual machine receives a BFD detection message of a second virtual machine, acquiring predetermined duration and each sample time interval of predetermined quantity; according to the predetermined duration and each sample time interval of the predetermined quantity, obtaining a feature value, wherein the feature value is used for representing possibility of occurrence of failures of applications in the second virtual machine; and for one application which is running in the second virtual machine, comparing the feature value with a preset failure determination standard of the application and determining whether the application fails or not according to a comparison result. According to the invention, by comparing the feature value with preset failure determination standards of different applications, failure determination and processing are performed, so the BFD detection is enabled to be applicable for requirements of different types of applications / services; and the unified failure determination standard is not used for all applications / services any longer, so failure mis-determination caused thereby is reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a BFD detection method and device. Background technique [0002] In the current virtualized cloud environment, fault detection usually adopts the heartbeat mechanism between virtual machines (which can be equivalent to a communication node). The time interval Δi sends a heartbeat message to node q, and node q receives the heartbeat message at a fixed time interval Δt. If the heartbeat message from node p is not received within the specified time (such as three Δi), Then it is determined that node p has failed; for example, if several packets are lost continuously, that is, node q does not receive a response from node p for several time intervals, then node p is considered to be faulty. [0003] The time for such heartbeat detection is usually at the level of seconds or even minutes, which cannot meet the reliability requirements of telecommunication services that ...
