Problems solved by technology

The user's bandwidth occupation and demand are increasing, resulting in the congestion of the carrier's backbone network bandwidth
Finally, it affects the user experience and hinders the development of operators' broadband services
It is impossible to accurately schedule traffic, and the switching speed of faulty content sources is slow. ECS will increase changes in network structure and affect DNS performance

Embodiment Construction

[0071] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0072] attached Figure 1-10 It can be seen that a CDN optimal scheduling method based on local DNS,

[0073] Including: ICP content user experience optimization system and Internet content user experience optimization system;

[0074] Among them, the ICP content user experience optimization system is aimed at the domain names frequently visited by users. By deploying the ICP authorized domain name server next to the ICP user experience optimization system, the forwarding server is configured on the ICP user experience optimization system as the address of the ICP authorized domain name server. Forward resource acquisition instead of recursion;

[0075] The Internet content user experience optimization system is aimed at other domain names other than ICP that users rarely visit. It obtains local dial-up test results through Testor's global resource library, and ...

Abstract

The invention relates to a CDN optimal scheduling method based on local DNS, comprising: an ICP content user experience optimization system and an Internet content user experience optimization system.IN the ICP Content User Experience Optimization System, fora domain name often visited by users, ICP's Authorized Domain Name Server is deployed next to the ICP User Experience Optimization system,aforwarding server is configured as the address of ICP authorized domain name server on ICP user experience optimization system, and the resource is obtained directly through domain name forwarding, and the local dialing test result is obtained through Tesse global resource library, and the optimal resource list is returned according to the user's strategy. The user experience is enhanced; local DNS service capabilities are enhanced; fault content source second-level switching is performed; the backbone network bandwidth of operators is saved. On the one hand, the access experience of users isenhanced, and the competitiveness of operators is enhanced; on the other hand, the backbone network bandwidth of the operators is greatly saved and the cost of the operators is reduced.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a CDN optimization scheduling method based on local DNS. Background technique [0002] DNS resolution is the "first hop" for us to access the Internet. In order to be faster and more stable, the industry now generally adopts smart DNS for resolution. Smart DNS resolution is an important part of CDN. Its principle is to assign the host record of the server to the user according to the correspondence between the IP of the stored entry and the location of the user, that is, to make corresponding differences for the same domain name according to the source of the requesting user. analysis. In the CDN network, the GSLB global load balancing is realized according to the intelligent DNS, and the cache servers that can be requested are distributed nearby. Therefore, the scheduling accuracy of the CDN depends on the intelligent resolution of the DNS. [0003] But smart DNS is not perfect, be...
