Problems solved by technology

[0004] In the existing technology, on the one hand, the scheduling is only performed after the edge node fails, and before the edge node fails, the service quality is likely to be in a poor state; on the other hand, it is also possible to schedule the service to Accelerated service on edge nodes with poor QoS
In this way, the user's access request cannot be effectively accelerated, which will greatly affect the CDN acceleration service quality

Abstract

The invention provides a CDN service scheduling method and system, and the method comprises the steps: enabling a scheduling system to periodically generate a network health coefficient of each edge node according to the real-time network quality of each edge node; when the network health coefficient of the target edge node is smaller than a preset threshold value, the scheduling system determinesa domain name to be scheduled on the target edge node; the scheduling system determines all available edge nodes corresponding to a preset domain name to be scheduled, and obtains a network health coefficient of each available edge node; and the scheduling system determines an optimal edge node according to the network health coefficient of each available edge node, and schedules the domain nameto be scheduled to the optimal edge node. According to the CDN service scheduling method provided by the invention, the network quality of the edge node is reflected more directly and accurately through the network health coefficient. And the domain name to be scheduled is scheduled to the optimal edge node according to the network health coefficient of the available edge node, so that the problemof response failure or slow response when the user accesses the domain name can be avoided.

Description

technical field [0001] The invention relates to the technical field of file transmission, in particular to a CDN service scheduling method and system. Background technique [0002] Currently, CDN (Content Delivery Network, Content Delivery Network) provides acceleration services. Taking the domain name access service as an example, the specific process is as follows: the CDN plans the edge nodes of the CDN according to the geographical location or the network operator, and when the user accesses the domain name, the domain name can be accessed from the edge node. [0003] In the existing CDN cluster, each edge node is monitored by a corresponding monitoring device, and the monitored running status of the edge node is reported to the scheduling system. When a failure of an edge node is found, the scheduling system will schedule the service to other available edge nodes nearby. [0004] In the existing technology, on the one hand, the scheduling is only performed after the e...
