向未来互联网演进

随着互联网用户的不断增长、网络应用的日趋丰富、技术水平的持续提高,未来互联网发展的焦点已经不再单纯是简单的接入,而是在此之上的多层次的、具有高可扩展性的增值服务。文章在分析了向未来互联网演进4个不同阶段所面临的重大挑战后,提出目前下一代互联网中重要的IPv6技术已经难以胜任向未来互联网演进的需要。文章强调未来互联网虽然存在着多个研究方向和热点,但在一些基本问题上缺乏共识,因此对于未来互联网的研究需要从更基础的起点出发。

Evolving Towards the Future Internet

With an abundance of network applications and sustained improvements in technology,Internet development must be focused not only on simple access but also on multilevel and highly scalable value added services.This paper analyzes challenges in the four different stages of evolution to future Internet and suggests IPv6 is not satisfactory for the future Internet.Many avenues of research are being explored for future Internet,but there is still a lack of consensus on basic issues.More research is required into the fundamentals of the future Internet.
