摘　　要：未来宽带互联网将是以内容为中心的网络,内容流量的飞速增长以及用户QoS需求的不断提高,使得互联网内容传输技术乃至架构面临全新的挑战。在分析当前互联网内容传输优化技术发展最新动态以及以内容为中心的新型互联网架构研究进展的基础上,介绍了一种"演进式革命"的设计思想及一种基于虚拟化重叠网的下一代网络架构。Future broadband Internet will be a content-centric network with fast growing traffic and user QoS requirements,which puts new challenges to traditional content delivery technologies as well as its architecture.Facing this problem,two methods are proposed,which are known as Incremental and Clean-Slate approaches.Based on the analysis of current development trends of Internet content delivery optimization technology as well as the research progress on Internet content-centric architecture,this paper proposes an＂Evolutional Clean-Slate＂design philosophy,and gives a detail design of virtualization overlay network based on Next Generation Broadband Network design.
