下一代互联网体系结构基础研究及探索

随着人们对互联网的规模、功能和性能等方面的需求越来越高,以IPv4协议为核心技术的互联网面临着越来越严重的技术挑战.近年来,下一代互联网及其应用的研究引起了许多国家的特别关注,发达国家相继启动了下一代互联网研究计划,意图掌握未来互联网核心技术.国家"九七三"计划项目"新一代互联网体系结构理论研究",经过近5年的研究,在探索新一代互联网体系结构所面临的基础问题上,取得了初步的研究结果:提炼出新一代互联网体系结构研究的4个基本科学问题;初步提出了一种多维可扩展的新一代互联网体系结构及其基本要素;从基于IPv6的规模可扩展、基于可扩展交换节点的性能可扩展、基于真实IPv6地址的安全可扩展、基于4over6机制的功能可扩展和基于端到端无连接服务质量控制的服务可扩展等5个方面对新一代互联网多维可扩展体系结构进行了深入研究.这5项基本要素将构成未来新一代互联网的基础.

Research and Exploration of Next-Generation Internet Architecture

As the demands on the size,functionality,performance and other aspects of Internet keep increasing,current Internet which using IPv4 as the core technology is facing severe technical challenges.In recent years,next-generation Internet and its applications has gained the particular concerns of many countries,and the developed countries have launched the national next-generation Internet research projects intended to seize the core technology of future Internet.National Basic Research Program of China(973 Program) "Research of Future Internet Architecture",after nearly five years of research,made the preliminary findings in exploring the basic issues of new-generation Internet architecture: Refined four basic scientific questions of new-generation Internet architecture,preliminarily proposed multi-dimension scalable architecture of new-generation Internet and its basic elements,extended in-depth study of new-generation Internet architecture to the expansion of five multi-dimension aspects,such as the scale-scalability based on IPv6,performance-scalability based on scalable exchange node,security-scalability based on authentic IPv6 addressing,function-scalability based on 4over6 mechanism,and service-scalability based on end-to-end connectionless Quality-of-Service control.These five basic elements will form the basis of new-generation Internet.
