新一代网络体系结构:需求目标、设计原则及参考模型

New Generation Network Architecture: Requirement Goals, Design Principles and Reference Model

本文按照网络体系结构认知框架,遵循“需求目标→设计原则→具体实现”的合理研究思路,对满足下一代网络发展需求的新一代网络体系结构进行了研究。首先对下一代网络的概念进行了比较全面的分析,在此基础上明确地归纳了新一代网络体系结构的10条主要需求目标;然后通过总结、吸收相关领域的最新成果,研究提出了与这些需求目标相适应的若干新的网络体系结构设计原则;最后,以这些新的设计原则为指导,研究并建立起了满足下一代网络发展需求的新一代网络体系结构INSA参考模型,为满足下一代网络发展需求的新一代网络体系结构的研究提供了较好的思路并奠定了良好的基础。

According to the Cognitive Framework for Network Architecture, we undertake research on the new generation network architecture that sufficing the development requirements of next generation network by strictly following the sound approach as ＂requirement goals→design principles→reference model＂. First we present 10 primary requirement goals of new generation network architecture after a relatively complete analysis of the next generation network concepts, and then bring some new network architecture design principles that meet such requirement goals by absorbing and summarizing recent research progresses in related fields. Finally, under guidance of such design principles, we put forward a new network architecture reference model named INSA. This paper casts a light on the research of next generation network architecture and establishes one promising foundation for further research.
