Abstract

The invention relates to the technical field of internet domain names, and discloses a distributed storage system for DNS (Domain Name System) cache in an edge network, which comprises a plurality of distributed primary cache servers positioned in the edge network and a secondary cache server positioned in a core network, wherein the cache data in the secondary cache server is synchronously mapped to each primary cache server in the same edge network according to a consistent hash algorithm and the number of the primary cache servers in the same edge network. The cache data in the core network is mapped to the edge network, so that the DNS query request can be completed in the edge network, the idle bandwidth in the edge network is fully utilized, the bandwidth pressure of the core network and the concurrent pressure of the recursive server are reduced, and the DNS query efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of Internet domain names, in particular to a distributed storage system in which DNS is cached in an edge network. Background technique [0002] The Domain Name System (DNS for short) is a service of the Internet. It is a distributed database that maps Internet domain names that are easy for humans to remember and IP addresses that are easy for computers to recognize. When we use the Internet, we usually directly enter the domain name of the corresponding website, rather than the IP address of the server where the website is located. The conversion between the domain name and the IP address is done by the DNS client and the DNS server running the DNS protocol. There are two types of DNS servers: DNS recursive server and DNS authoritative server. [0003] The existing DNS network topology is attached figure 1 shown. The terminal or server equipment we usually use exists as a DNS client, and usually direc...
