文中在理解域名解析系统结构的基础上,针对 DNS 系统面向主机解析存在的缺陷,将一体化网络中面向资源的解析机制引入 DNS 系统,提出了兼容 DNS 的资源解析系统.该系统在原有 DNS 的查询类型的基础上添加了新的查询类型方式 RSID,并采用面向资源的解析方式,利用层次性分布式结构实现了一体化网络资源解析系统与现有 DNS 系统的过渡.新系统利用服务标识面向资源解析的优势,克服了目前域名解析系统面向地理位置解析的问题,并且使用分层的分布式系统,在一定程度上提高了原有一体化网络的资源查询效率.
文中在理解域名解析繫統結構的基礎上,針對 DNS 繫統麵嚮主機解析存在的缺陷,將一體化網絡中麵嚮資源的解析機製引入 DNS 繫統,提齣瞭兼容 DNS 的資源解析繫統.該繫統在原有 DNS 的查詢類型的基礎上添加瞭新的查詢類型方式 RSID,併採用麵嚮資源的解析方式,利用層次性分佈式結構實現瞭一體化網絡資源解析繫統與現有 DNS 繫統的過渡.新繫統利用服務標識麵嚮資源解析的優勢,剋服瞭目前域名解析繫統麵嚮地理位置解析的問題,併且使用分層的分佈式繫統,在一定程度上提高瞭原有一體化網絡的資源查詢效率.

Aiming at the defects existed in domain name system faced to server resolving,based on understanding of domain name resol-ving system structure,combine the recourse resolving strategy defined in the universal network with the DNS,and design a DNS compati-ble resolving system. In this system,add a new query type named RSID into the original DNS,and utilize the resource oriented resolving method. A hieratical and distributed architecture is designed to smoothly transform the current domain name system to resource resolving system in universal network. This new system takes advantage of the service identifier in resolving resource,and meanwhile it overcomes the problem of relying on server's physical address in the current DNS. What's more,this system uses the layered distributed architecture, therefore the resource query efficiency in the original universal network is improved.
