Embodiment 1

[0038] According to the embodiment of the present application, an embodiment of a domain name system-based data scheduling method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0039] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. image 3 It shows a hardware structure block diagram of a computer terminal (or mobile device) for realizing the domain name system-based data scheduling method. like image 3 As shown, the computer terminal 10 (or mobile device 10) may include one or more (shown by 302a, 302b, ..., 302n in the figure) processor 302 (th...

Embodiment 2

[0133] According to the embodiment of the present application, an embodiment of a domain name system-based data scheduling method is also provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0134] Under the operating environment of the above-mentioned embodiment 1, the present application provides the following Figure 8 The data scheduling method based on Domain Name System is shown. Figure 8 It is a flowchart of a domain name system-based data scheduling method according to Embodiment 2 of the present application. like Figure 8 As shown, the method may include the following steps:

[0135] Step S82, the edge server receives the content request sent by the client...

Embodiment 3

[0160] According to an embodiment of the present application, a domain name system-based data scheduling device for implementing the above domain name system-based data scheduling method is also provided, such as Figure 9 As shown, the apparatus 900 includes: an acquiring module 902 , a sending module 904 and a receiving module 906 .

[0161] Wherein, the acquiring module 902 is configured to obtain the address information of the edge server in the content distribution network by completing domain name scheduling in the content distribution network; the sending module 904 is configured to send the content request to the edge server based on the address information, wherein the content request includes at least : domain name, address information of the client terminal; the receiving module 906 is used to receive the data directly returned by the edge server if the edge server has locally cached the data requested by the content request; if the edge server has not locally cached...

Abstract

The invention discloses a data scheduling method and system based on a domain name system. The method comprises the steps that a client terminal obtains address information of an edge server in a content distribution network by completing domain name scheduling in the content distribution network; the client terminal sends a content request to the edge server based on the address information, andthe content request at least comprises a domain name and the address information of the client terminal; if the edge server locally caches the data requested by the content request, the client terminal receives the data directly returned by the edge server; and if the edge server does not cache the data requested by the content request locally, the client terminal receives the data requested by the edge server through accessing the scheduling center of the content distribution network. The technical problem that in the video playing process in the prior art, the hit rate is low due to the factthat the playing request is dispersed to the multiple CDN nodes is solved.

Description

technical field [0001] The present application relates to the field of data scheduling, in particular, to a domain name system-based data scheduling method and system. Background technique [0002] The acceleration of the existing commercial CDN (Content Delivery Network, Content Delivery Network) is basically based on the domain name. The scheduling of most users and traffic is basically based on DNS. The specific principles are as follows: figure 1 As shown, the user accesses a live broadcast URL: http: / / host.com / app / steam.flv live broadcast content; the operator's recursive Forward DNS goes to the root (.) authoritative DNS to query the NS(Name Server, name server) record, root (.) returns the NS of com. authoritative DNS; the operator’s Forward DNS goes to com. authoritative DNS to query the NS record of host.com., com. returns the NS of host.com.; the operator’s Forward DNS goes to the host authoritative DNS to query the A record of host.com. The host authority return...
