Network fault detection method and device

Abstract

The embodiment of the invention discloses a network fault detection method and a network fault detection device, applied to the field of communication technologies. In the method of the embodiment, a fault detection server acquires network communication information of a client in a content delivery network system, then the network communication information is matched with a preset fault model library, if the network communication information is matched with description information of a first fault model, namely values of a plurality of parameters in the network communication information are respectively in value ranges of corresponding parameters in the description information of the first fault model, it determines that a communication fault accords with the first fault model, and warning is sent to a corresponding content delivery network node. Compared with manual fault cause analysis in the prior art, the method provided by the embodiment of the invention can learn the fault the type of the current communication fault by matching collected information with the fault model library, so that a fault cause can be rapidly and accurately acquired by analyzing.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting network faults. Background technique [0002] Content delivery network (Content Delivery Network, CDN) is to publish the content of the source station to the edge node closest to the user device, so that the user device can obtain the accessed content nearby, and improve the response speed and success rate of user access. The edge nodes are referred to as CDN nodes. [0003] In the existing technology, if the monitoring system detects a CDN node failure, it needs to analyze the cause of the failure through manual positioning and analysis, and then send an alarm, which takes a lot of time; and the monitoring system provides the operation and maintenance personnel with data comparison to analyze the cause of the failure Simple, such as delay, packet loss rate, and the network protocol address of the faulty machine, etc., the accuracy of the...
