Problems solved by technology

[0004] During the above content distribution process, every time the user device initiates a domain name resolution request, LDNS will go to the authorized domain name server of the source server to make a domain name resolution request after the domain name cache time expires, and each time it requests content, it must go to GSLB to do it once. Global load balancing, the interaction process for user equipment to obtain distributed content is long, which is not conducive to the rapid distribution of content

Embodiment Construction

[0042] The main idea of ​​the implementation method and system of the content distribution of the present invention is that when the local domain name system receives a domain name resolution request, it forwards the domain name resolution request to the pre-configured local load balancing (SLB) server of the edge node, thereby shortening the interaction of domain name resolution process, speed up content delivery, and improve user experience.

[0043] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0044] Such as figure 2 As shown, the implementation methods of content distribution include:

[0045] Step 201: The local domain name system (Local Domain Name System, referred to as LDNS) receives the domain name resolution request sent by the ...

Abstract

The invention relates to a content distribution implementation method and system, wherein the method comprises the following steps: a local domain name system (LDNS) receives a domain name resolution (DNS) request sent by user equipment, forwards the request to a local server load balance (SLB) server of a preset edge node; the SLB server returns a domain resolution response carrying the corresponding IP address to the LDNS; and the LDNS returns the domain resolution response to the user equipment. The method and system of the invention can quicken the process of the domain resolution.

Description

technical field [0001] The present invention relates to the field of content distribution, in particular to a method and system for realizing content distribution. Background technique [0002] Content delivery network (content delivery net referred to as CDN) is a new network architecture superimposed on the existing Internet network layer, such as figure 1 As shown in , the CDN network consists of global load balancing nodes and several edge nodes. The edge node is composed of SLB server and several edge servers, and the edge node caches the content provided by the content provider. [0003] The CDN network routes the request of the user equipment to a healthy edge node that is closer to the user equipment. When the edge node provides the requested content to the user equipment, the content can be pushed down to the edge node first, or pulled down to edge nodes. When the user device requests the content pointed to by the URL, it usually initiates a domain name resolutio...
