Problems solved by technology

[0002] Existing detection methods for CDN availability generally detect the availability of the destination CDN through some detection points. The probe data sent by a probe point does not necessarily reach all the destination CDNs; the CDNs that cause the probe data not to arrive are actually not monitored

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 Shown: A method for monitoring availability of a CDN deployed in anycast mode, including the following steps:

[0022] Step 1: Select a detection node to detect the availability of the destination CDN node, each destination CDN node has at least two detection data reachable from the detection point, and store the detection results.

[0023] According to the existing resources, deploy the detection program in major cities and different operators in China (try to select as many major cities as possible to cover multiple operators), and detect the availability of the destination CDN node every minute; when selecting, ensure that every Each target CDN node must have at least two detection points that can reach the detection data (by checking the log on the target CDN to determine whether any detection points have arrived); ...

Abstract

The present invention provides a method for monitoring the availability of a CDN deployed in an anycast manner, comprising the following steps: Step 1: selecting a detection node to detect the availability of a destination CDN node, and each destination CDN node has at least two detection points that can reach the detection data ; Step 2: Obtain the detection nodes that reach the CDN node according to the detection log on the destination CDN node; Step 3: Determine whether the number N of detection nodes that the destination CDN node has reached within a certain period of time satisfies N<1, and if so, judge the purpose CDN is unavailable; otherwise, go to step 4; step 4: judge whether N satisfies N≥2, if so, go to step 5, otherwise output an alarm; step 5: judge the detection node that arrives at the destination CDN node within a certain period of time The probability n that the target CDN node is unavailable, and the availability of the target CDN node; the present invention improves the accuracy of monitoring through bidirectional analysis.

Description

technical field [0001] The invention relates to a method for monitoring availability of a CDN node, in particular to a method for monitoring availability of a CDN deployed in anycast mode. Background technique [0002] Existing detection methods for CDN availability generally detect the availability of the destination CDN through some detection points. The probe data sent by a probe point does not necessarily reach all the destination CDNs; the CDNs that cause the probe data not to arrive are actually not monitored. Contents of the invention [0003] The present invention provides a method for monitoring availability of a CDN deployed in anycast mode through bidirectional analysis, which improves monitoring accuracy. [0004] The technical solution adopted by the present invention is: a method for monitoring availability of a CDN deployed in anycast mode, comprising the following steps: [0005] Step 1: Select the detection node to detect the availability of the destinat...
