A hierarchical alarm analysis method and system based on content distribution network

Abstract

The invention discloses a hierarchical alarm analysis method and a hierarchical alarm analysis system based on a content delivery network, which aim to realize precise real-time alarm and improve service quality of the CDN (content delivery network) of the internet. The technical scheme includes that the method includes the steps: data acquisition; single node analysis by dividing acquired data according to a target IP (internet protocol), and placing the data with the same nodes into an analysis container for single node analysis; regional analysis by summarizing abnormal data reported after single node analysis, and placing the abnormal data into corresponding analysis containers for analysis according to regions; source analysis by summarizing abnormal data after regional analysis, analyzing all the abnormal data, and judging whether the problem lies in a source according to the occupied proportion in all the regions; and alarm filtering by obtaining upper abnormal alarm information after single node analysis, regional analysis and source analysis, and filtering lower repeated alarming by means of reverse matching of the upper lower alarm data.

Description

technical field [0001] The invention relates to a computer network service quality monitoring technology, in particular to an alarm analysis method and system for providing abnormal service status on a content distribution network (CDN). Background technique [0002] Quality of service is a security mechanism of the network and a technology used to solve problems such as network delay and congestion. The commonly used methods include classification, labeling and priority setting. However, with the rapid development of Internet services, the quality of service requirements for network applications are no longer limited to the underlying network control, and Content Delivery Network (CDN) technology has emerged as the times require. It is a network coverage layer specially optimized for distributing broadband rich media on traditional IP networks. From a broad perspective, CDN represents a network service model based on quality and order. The purpose of CDN is to improve the...

Problems solved by technology

However, due to the complexity of its interaction process and network environment, there are still many problems that affect the quality of service in the application process.

[0003] The service quality bottleneck of traditional network applications mainly exists in the network problems between end users and application servers. However, the application of CDN services has greatly reduced the main causes of low service quality caused by long routes and cross-operators.

However, the adoption of CDN also brings new problems with its own characteristics: abnormal acceleration node back-to-source, edge node traffic running high and flat, edge node service exception, domain name resolution coverage exception, etc.

However, although the current monitoring method can effectively obtain problem data, it lacks a hierarchical structure understanding of the essence of the problem and an analysis method for the characteristics of CDN. With the popularization of CDN applications, the existing analysis method cannot effectively use test data to achieve comprehensive , Effective analysis to generate alarms, greatly increasing the workload of human analysis and processing
