Problems solved by technology

[0009] However, if users use a third-party caching DNS server, the optimized scheduling policy on the DNS server of the communication operator will not take effect for these users, resulting in poor user access physical examination and higher operator costs.
However, neither the above-mentioned traditional DNS resolution nor DNS hijacking system can solve this problem.

Embodiment Construction

[0039] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] Such as image 3 As shown, a bypass caching domain name resolution method includes:

[0041] Step S1000, the client sends a DNS resolution request, and the DNS resolution request carries domain name and target DNS server information;

[0042] Step S2000, the DNS resolution request is sent to the external network and the DNS bypass cache subsystem through an optical splitter or a router;

[0043] Step S3000, the DNS bypass cache subsystem receives the domain name system DNS resolution request sent by the client, and confirms the...

Abstract

A bypass caching domain name resolution method, comprising: step S1000, the client sends a DNS resolution request, the DNS resolution request carries domain name and target DNS server information; step S2000, the DNS resolution request is sent through an optical splitter or a router to the external network and the DNS bypass cache subsystem; step S3000, the DNS bypass cache subsystem receives the domain name system DNS resolution request sent by the client, and confirms the domain name and target DNS server information carried in the DNS resolution request; step S4000 , the DNS bypass caching subsystem determines whether the target DNS server is in the blacklist; Step S5000, the DNS bypass caching subsystem returns a domain name resolution result to the client. The invention can improve the communication operator's ability to schedule user traffic.

Description

technical field [0001] The invention relates to a bypass cache domain name resolution method and system. Background technique [0002] In the IP (Internet Protocol, Internet Protocol) network, the Domain Name System (DNS) is one of the most critical basic services of the Internet, providing fundamental support for many network applications. (Domain Name) and the network-recognizable IP address for conversion. The conversion between domain name and IP address is called domain name resolution, and the network host that performs domain name resolution can be called DNS server. Through the query service of the domain name system DNS server, the entrance of the required site or resource can be found, and then the site or resource can be accessed. [0003] At present, a DNS result process will encounter two kinds of DNS devices, namely the caching DNS server and the authoritative DNS server. [0004] Caching servers are usually managed by communication operators, such as China ...
