| 中文摘要: |
| 随着互联网的迅速发展,互联网名字空间结构及其解析服务面临着新的挑战.IP地址同时用作设备的位置标识和设备的身份标识、语义过载;当前的名字空间解析系统DNS存在着服务模式单一、更新速度慢、资源描述能力不够强等缺点,不能满足许多新型应用的要求;而NAT、各种代理、防火墙等网络中间件的存在也破坏了互联网的体系结构和名字空间.针对这些问题,研究者提出了许多方案来改进互联网的名字空间结构及其解析服务.分析了当前的互联网名字空间结构及其解析服务存在的问题,并对目前的各种互联网名字空间改进方案进行了分类、综述与比较,并展望了进一步的研究方向. |
| 英文摘要: |
| With the rapid growth of Internet, the structures and resolutions of Internet namespaces are facing with new challenges. IP address is overloaded in semantics because it is used to represent both the location and the identity of a device. The namespace resolution system DNS can’t satisfy many new application demands with its unique service model, slow update speed, and weak capability in resource description. Many network middleboxes, such as NAT, various agents and firewalls, also destroy the Internet architecture and the Internet namespaces. Based on these, researchers bring forth many solutions to improve the structures and resolutions of Internet namespaces. This paper analyzes the problems in the structures and resolutions of current Internet namespaces, and then makes categories, surveys, and comparisons on the improvement solutions to them. Finally, future research trends on this area are discussed. |
