Method, device, device and medium for dns scheduling of user terminal gateway equipment

Abstract

The invention provides a DNS scheduling method, device, equipment and medium of user terminal gateway equipment. The method includes: comparing the domain name resolution result with a pre-configured set of IP address segments in the network; encapsulating the IP addresses falling into the set of IP address segments in the network in the domain name resolution result into the address list of the reply message The front end of the network encapsulates the IP addresses that do not fall into the set of IP address segments in the network at the end of the address list of the reply message. According to the embodiment of the present invention, optimizing the DNS cache module on the user terminal gateway device can solve the scheduling error problem caused by enabling the DNS cache "cycle rotation" function by default, configure optimal network resources for users, and improve user access to the Internet. quality.

Description

technical field [0001] The present invention relates to the technical field of Internet DNS, in particular to a method, device, device and medium for realizing DNS scheduling by user terminal gateway equipment. Background technique [0002] DNS (Domain Name System, domain name resolution system) is the most basic and core service in the Internet architecture. Its function is to realize the mutual mapping between domain names and IP addresses, so that Internet users can easily access the Internet without having to remember The boring and cumbersome IP number string provides fundamental support for many network applications. DNS requests occur at the first link when users access the Internet. ICP (Internet Content Provider, Internet Content Provider) content resources, CDN (Content Distribute Network, Content Distribution Network), etc. all rely on the correct scheduling of DNS to guide user traffic to The most suitable resource node. [0003] DNS can be roughly divided into...

AI Technical Summary

Problems solved by technology

[0005] In the existing solution, there is a scheduling error in the DNS caching function of the user terminal gateway device, because the internal DNS of the user terminal gateway device will cache the domain name resolution IP, and can only respond to the request of the user terminal in a round-robin manner, resulting in higher-level The scheduling policy of optimal network resources configured by the operator's LOCAL DNS fails, and users may be transferred away from the local optimal resources by mistake, affecting the quality of users' Internet access and reducing their Internet experience
