Abstract

Internet has become the most important information infrastructure supporting modern socio-economic development, social progress and technological innovation. Invented 30 years ago, today Internet is facing increasingly severe technical challenges. This paper introduces the progress of the major international new-generation Internet research plans; analyzes its basic characteristics and the principal contradictions during the development; detailedly introduces the research carried out by 973 Project “Research of Future Internet Architecture” on the key scientific issues of new-generation Internet architecture and its latest research results; and looks to the future of the research-focus faced with the new situations of the basic research of new-generation Internet architecture as well as the new demands of innovative applications on Internet architecture.
