一种去中心化的域名服务本地化模型

A decentralized domain name service localization model

域名系统(Domain Name System,DNS)作为管理网络空间资源名称与IP对应关系的网络基础设施,在提供广泛的域名解析服务的同时,也存在性能和安全隐患。针对传统DNS系统的中心化树状层次结构引起的对根域名服务器的严重依赖以及可能导致的系统脆弱性,设计了一种去中心化的域名服务本地模型,通过在去中心化互联模型中整合多源数据,重构域名信息解析优先级记录和相应存活时间,以保证域名数据的唯一性及高优先级;同时基于本地数据记录重构模型实现域名解析的快速响应,形成本地DNS数据记录重构模型和域名解析服务模型,实现快速、准确、可靠的域名解析服务。

The Domain Name System(DNS)is a network infrastructure that manages the correspondence between names and IPs in cyberspace resources.While providing a wide range of domain name resolution services,it also has risks of performance and security.In order to avoid the system fragility caused by the heavy reliance on the root domain name server,which caused by the centralized tree-like hierarchy of the traditional DNS system,this paper designed a decentralized domain name service localization model.This model,through integrating multi-source data in the decentralized interconnection model,reconstructed the resolution priority records and the corresponding survival time after the domain name information was sorted to ensure the uniqueness and high priority of the domain name data.At the same time,based on the local data record reconstruction,the model realized the rapid response of the domain name resolution.The whole model consists of the local DNS data record reconstruction module and the domain name resolution service module,and realizes fast,accurate and reliable domain name resolution services.
