Embodiment 1

[0038] According to an embodiment of the present application, an embodiment of a method for data scheduling based on a domain name system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings may 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 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 A block diagram of the hardware structure of a computer terminal (or mobile device) for implementing a method for data scheduling based on a domain name system is shown. like image 3 As shown, the computer terminal 10 (or mobile device 10 ) may include one or more (shown as 302a, 302b, . or programmable logic device FPGA o...

Embodiment 2

[0133] According to an embodiment of the present application, an embodiment of a data scheduling method based on a domain name system is also provided. It should be noted that the steps shown in the flowchart of the accompanying drawings may 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 herein.

[0134] Under the operating environment of the above-mentioned Embodiment 1, the present application provides such as Figure 8 The data scheduling method based on the domain name system is shown. Figure 8 It is a flowchart of a method for data scheduling based on a domain name system 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 termina...

Embodiment 3

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

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

Abstract

The present application discloses a method and system for data scheduling based on a domain name system. The method includes: the client terminal obtains the address information of the edge server in the content distribution network by completing the domain name scheduling in the content distribution network; the client terminal sends a content request to the edge server based on the address information, wherein the content request includes at least the domain name: name and address information of the client terminal; if the edge server caches the data requested by the content request locally, the client terminal will receive the data directly returned by the edge server; if the edge server does not cache the data requested by the content request locally, then The client terminal will receive the data requested by the edge server by accessing the dispatch center of the content distribution network. The present application solves the technical problem of low hit rate in the process of playing video in the prior art because the playing requests are scattered to multiple CDN nodes.

Description

technical field [0001] The present application relates to the field of data scheduling, and in particular, to a method and system for data scheduling based on a domain name system. Background technique [0002] The acceleration of the existing commercial CDN (Content Delivery Network, Content Delivery Network) is basically based on the acceleration of 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 URL: http: / / host.com / app / steam.flv for the live 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 The DNS goes to the host authoritative DNS to query the A record of host.com....
