Problems solved by technology

[0003] However, the inventor found in the process of implementing the present invention that the above-mentioned method in the prior art has at least the following defects: since the processing of DNS resolution requests is all completed by the DNS server, the DNS server can only handle a single type of DNS resolution request, unable to support more types of DNS resolution requests
Moreover, the domain name lookup table in the DNS server is fixedly configured by operation and maintenance personnel, which has poor scalability and cannot flexibly set different scheduling rules according to actual application scenarios

Abstract

The invention discloses a scheduling system and method based on a DNS. The method comprises the following steps: a DNS access module analyzes a received DNS resolution request, determines request parameter information corresponding to the DNS resolution request according to an analysis result, and provides the request parameter information to a configuration scheduling module; the configuration scheduling module acquires request parameter information provided by the DNS access module; and according to a preset scheduling rule, determining a domain name resolution result corresponding to a domain name contained in the request parameter information, and providing the determined domain name resolution result to the DNS access module, so that the DNS access module returns a DNS response message according to the domain name resolution result. Therefore, according to the invention, the DNS scheduling system is divided into two layers, so that the access layer can conveniently extend according to the type of the DNS resolution request so as to support more types of DNS resolution requests. Moreover, the expandability can be improved by independently setting the scheduling layer, so that different scheduling rules can be flexibly set in the scheduling layer according to actual application scenarios.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a DNS-based scheduling system and method. Background technique [0002] Currently, in order to implement domain name resolution operations, an authorized DNS (Domain Name System, domain name resolution) server is usually responsible for processing DNS resolution requests and returning corresponding resolution results. Specifically, when the DNS server processes the DNS resolution request, it first needs to analyze the DNS resolution request to obtain relevant information such as the domain name contained therein, and then, based on the preset domain name lookup table, query the domain name contained in the DNS resolution request. The corresponding domain name resolution result is returned to the requester. [0003] However, the inventor found in the process of implementing the present invention that the above-mentioned method in the prior art has at least the following defects...
