归纳了对下一代网络的共识与分歧，分析了产生分歧的原因，提出应重视网络体系结构研究，包括重新认识边缘论（end-to-end argument）、光通信与分组交换技术的融合、UNI模式向NNI模式的过渡，同时要关注网络结构和动力学规律的基础研究。

This paper summarized the agreement and divergence about viewpoints of the next generation of network, then the reasons of divergence were analyzed. It pointed out that much attention should be paid to the researches on network architecture, including rethinking of End-to-End Argument, combining of packet switching with optical networking ,and evolution from UNI overlay architecture to unified NNI architecture. Finally, the importance of basic researches on the Internet, such as the network dynamics, is also put forward.
