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.
