摘要
指出了下一代网络体系结构的基本共识和在认识上存在的某些分歧 ,探讨了分歧存在的原因。分析了下一代网络体系结构 ,如Internet体系结构的初衷与需求变化 ;边缘论原则随着网络应用环境的变化而受到的挑战 ;光通信与分组交换技术的融合 ;UNI和UUI模式以及下一代示范网和试验网。提出了下一代网络应用模式是网格应用 ,它是把整个因特网整合成一台巨大的超级计算机 ,实现计算机资源、存储资源、数据资源、信息资源、知识资源和专家资源全面共享。网络的根本特征不一定是它的规模 ,而是资源共享 ,消除资源孤岛。
The basic common agreements and some disagreements on the next-generation network of architecture are pointed out. Causes of these disagreements are explored. The next-generation network architecture is analyzed from following aspects: the initial design of the Internet architecture and its demand are changing; end-to-end Argument face challenges with the change of the network application environment; The Circuit Switch and Packet Switch technology are amalgamated; The mode of UNI and the mode of UUI are described. It is pointed out that the next generation network application mode will be the grid application. The grid can integrate the whole network into a great super-computer, which can realize shared computer resources, shared storage resources, shared data resources, shared information resources, shared knowledge resources and shared expert resources. The essence of the grid relies on its resource share and the elimination of resource isolation rather than its scale. At last, the research progress of the Vega Grid developed by the Chinese Academy is introduced.
