Abstract

The invention relates to a domain name resolution service system with an intelligent buffer and a service method thereof in the technical field of network service, wherein the system comprises a domain name resolution module, an intelligent buffer module, an intelligent buffer updating module, a domain name resolution mistake judgment module and a domain name resolution mistake processing module;the method comprises the update of an iterative inquiry and the intelligent buffer, the judgment of a domain name resolution mistake and the processing of the domain name resolution mistake. When a fault of a domain name authorization server at a client end occurs, a correctly resolved result of the last time of a domain name influenced by the fault can be obtained to access a website or service corresponding to the domain name, so that the network browse of a user can not be influenced by the fault of the domain name authorization server; a safeguard can be supplied for the appointed important domain name and key service, the reliability of domain name resolution service is improved, and the influence of the fault of the domain name authorization server on website or service access is greatly reduced; and the invention is transparent for the user, and the software and the configuration of the client end need not to be modified.

Description

technical field [0001] The present invention relates to a system and method in the technical field of network services, in particular to a domain name resolution service system with intelligent caching and a service method thereof. Background technique [0002] Domain Name System (Domain Name System, DNS) is one of the most critical basic services of the Internet, providing fundamental support for many network applications. IP address. The stability and reliability of DNS service is the guarantee for the normal operation of the Internet. Network failures, server failures, misconfigurations and malicious attacks are important factors that affect the stability and security of DNS services. With the rapid increase in the number of Internet users and websites, the pressure on DNS services has increased, and the impact of failures on users has become more significant. [0003] When the authoritative domain name server fails to respond to the query request due to failure or atta...
