Embodiment Construction

[0033] The present invention is described in detail below in conjunction with accompanying drawing:

[0034] Such as figure 1 and figure 2 As shown, the present invention provides a load balancing method based on alias records in a DNS authorization system, comprising the following steps:

[0035] S1, configure multiple CNAMEX records on the authorized DNS server of the requested domain name; each CNAMEX record is used to record the mapping relationship between the same requested domain name and different CDN service provider domain names pointed to by the alias, and is also used to record the same requested domain name alias points to The weight value of each CDN service provider domain name;

[0036] For the convenience of description, CNAMEX records can be abbreviated as CX records. CX records comply with the DNS protocol specification, and can realize the alias of the same requested domain name to point to multiple other domain names, such as multiple CDN service provid...

Abstract

The invention provides a method and system for load balancing in a DNS system based on an alias record. The method includes the steps that a CNAMEX record is revised and added according to DNS protocol specifications, the aliases of the same domain name under the same view point to multiple other domain names, and therefore the same service website domain name in the same VIEW has access to multiple CDN service providers to conduct acceleration. In addition, weight indexes of traffic loads are added for the CNAMEX record, a user can reasonably share traffics to the different service providers according to the performance and the bearing capabilities of the CDN service providers, and the quality of CDN application services is optimized.

Description

technical field [0001] The invention belongs to the technical field of load balancing, and in particular relates to a load balancing method and system based on alias records in a DNS authorization system. Background technique [0002] CDN (Content Distribution Network, Content Distribution Network) is a new type of network content service system. The essence is: adding a layer of intelligent virtual network composed of multiple CDN nodes on the basis of the existing Internet. Constitute a CDN system. The CDN system can redirect the user's request to the CDN node closest to the user based on comprehensive information such as network traffic, connection of each CDN node, load status, distance to the user, and response time in real time. Improve user access speed. [0003] A CDN service provider refers to a service provider that provides the above-mentioned CDN services. The main service model is: accept the entrustment of a certain business website, and provide accelerated ca...
