Example Embodiment

[0060] Example one

[0061] See figure 1 As shown, the embodiment of the present invention provides a CDN traffic intelligent scheduling method, which specifically includes:

[0062] Step S1: Receive the domain name resolution request sent by the local domain name server DNS through the subdomain name provided by the website domain name authoritative DNS;

[0063] Step S2: Obtain the IP address of the local DNS according to the domain name resolution request;

[0064] Step S3: Use the IP address to identify the geographic location of the local DNS and the network service provider ISP;

[0065] Step S4: According to the geographic location and ISP, select a CDN service provider of the content distribution network according to preset rules;

[0066] Step S5: Send the selected domain name of the CDN service provider to the local DNS.

[0067] See figure 2 As shown, in step S4 of the above method, the preset rule is a manual strategy, and the specific process of selecting a CDN service provi...

Abstract

The invention discloses an intelligent dispatching method, a device and a system of content delivery network flow. The intelligent dispatching method comprises: receiving a domain name resolution request which is sent by a local DNS through a subdomain which is provided by a website domain authority DNS; according to the domain name resolution request, obtaining the IP address of the local DNS; utilizing the IP address to indentify the geographic location of the local DNS and network service provider ISP information; according to the geographic location and the ISP information, selecting a CDN service provider on the basis of a preset rule; sending a domain corresponding to the name of the selected CDN service provider to the local DNS. The invention builds an intelligent dispatching center between the existing CDN network frame and an operator website; when accessing the network of the operator, a netizen selects a proper CDN service provider according to the preset rule. The invention ensures that the operator can flexibly replace the existing CDN service provider so as to lead the operator to obtain CDN service with better cost performance.

Description

technical field [0001] The present invention relates to the field of network technology, and more specifically, to a method, device and system for intelligent scheduling of content distribution network traffic. Background technique [0002] The full name of DNS in English is Domain Name System, and its Chinese name is Domain Name System, which is used to name computers and network services organized into domain hierarchies. There is a one-to-one (or many-to-one) relationship between domain names and IP addresses on the Internet. Although domain names are easy for people to remember, machines can only recognize each other’s IP addresses. The conversion work between them is called domain name resolution. The resolution needs to be completed by a dedicated domain name resolution server, and DNS is the server for domain name resolution. DNS naming is used in TCP / IP networks such as the Internet to look up computers and services by user-friendly names. When a user enters a DNS ...
