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.
