CDN fault node isolation method and system based on operator network management data

By combining operator network management data with CDN node quality indicators to determine fault location and calculate isolation scores, the problem of insufficient accuracy and timeliness in CDN fault node isolation in existing technologies is solved. This enables precise isolation and traffic scheduling in complex network environments, reducing the risk of false isolation and congestion.

AI Technical Summary

Technical Problem

Existing CDN fault node isolation solutions suffer from insufficient accuracy and timeliness in complex carrier network environments, and the congestion exacerbated by mis-isolation. They are difficult to distinguish whether the fault originates from the CDN node itself or the upstream network, and can easily trigger a chain reaction of congestion.

Method used

By collecting operator network management data and CDN node quality indicators for time alignment and correlation, and combining operator network management data to determine fault location, an isolation score calculation model is constructed. An alarm-driven rapid triggering mechanism and a gradual traffic scheduling strategy are adopted to avoid false isolation and increased congestion.

Benefits of technology

It improves the accuracy and timeliness of isolation, reduces the false isolation rate, inhibits the escalation of congestion, forms an interpretable isolation decision system, and enhances the intelligence and controllability of CDN fault management.

Abstract

The invention discloses a CDN fault node isolation method and system based on telecom operator network management data, and relates to the technical field of CDN fault management and operation and maintenance, and the method comprises the steps that an operator network management center collects multi-stage network equipment and link data, and a CDN health center collects indexes such as node packet loss rate; comparing an index and a threshold value quality index degree which exceeds a threshold value, and marking a suspected node; querying network management data to locate a fault category; calculating a score by combining a fault position weight, and isolating if the score exceeds a threshold value and the fault position is a node or a direct connection link; eliminating nodes and scheduling traffic; and quickly triggering the alarm, subscribing the network management alarm, directly marking the suspected node and triggering the process. According to the method, the isolation accuracy of the CDN fault node is improved, and misjudgment caused by an upstream network fault is reduced; the isolation response time delay is shortened; congestion aggravation is inhibited; a quantifiable and configurable isolation decision system is formed, the operation and maintenance intelligence is improved, and the service quality and the user experience are optimized.
