Problems solved by technology

[0005] The public DNS first needs to obtain the access domain name of the CDN service system from the authoritative DNS in the CDN dispatching system, and then obtain the IP address of the cache server from the authoritative DNS of the CDN service system based on the access domain name, resulting in DNS resolution time longer
In addition, if the DNS service quality of a certain CDN service system is poor and the cache service quality is good, the CDN scheduling system will often not schedule the CDN service system to provide CDN services, resulting in the inability to implement the better cache service of the CDN service system. Take advantage of
Therefore, the scheduling quality of the CDN scheduling system is low

Abstract

The invention discloses a method and a device for dispatching a multi-CDN service system, belonging to the technical field of the Internet. The method includes: according to the preset view information and the access domain name in each of the CDN service systems pre-configured for the target domain name, initiating a pairing in each view to the authoritative DNS of each CDN service system The analysis request of the access domain name; receiving the analysis result carrying the IP address under each view returned by each CDN service system, and monitoring the cache service quality of the cache server corresponding to the IP address under each view; When receiving the target domain name resolution request for the target domain name, determine the target view corresponding to the target domain name resolution request, and return the target IP address. By adopting the invention, the scheduling quality can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for scheduling a multi-CDN service system. Background technique [0002] With the continuous development of Internet technologies, CDN (Content Delivery Network, content distribution network) services are also developing rapidly, and accordingly, the number of CDN service providers is also increasing. Some CDN customers often use the CDN service system provided by multiple CDN service providers to accelerate the CDN of the website. These CDN customers can monitor the service quality of each CDN service system through the CDN dispatching system, and real-time dispatch the CDN service system with better service quality for the website. Carry out CDN acceleration, wherein, the above-mentioned quality of service mainly includes DNS service quality and cache service quality, DNS service quality can be obtained based on factors such as the DNS resolution time o...
