随着计算技术和互联网业务的蓬勃发展,用户对网络应用提出了越来越高的要求,多样化的需求使得现有Internet架构难以适用,成为了网络业务进一步发展的瓶颈.文中在分析当前Internet网络存在的问题、总结本源性因素的基础上,指出了自适应是未来网络的发展方向,可控、可管、可扩展和可信是实现自适应特性应满足的基本指标.在介绍和分析现有自适应未来网络关键技术和体系架构的同时,深入讨论了相关技术和体系结构的优势和兼容性,并在此基础上提出了自适应的未来网络体系架构,为未来网络的研究提供了参考.
With the flourishing of Internet application and the growth of computing techniques, customers require Internet with higher and higher performance. Nevertheless, diversified requirement of customers and lacking of elasticity of Internet architecture lead to wasting much Internet resource. The Internet became the bottleneck for further development of Internet service. Based on analysis of the present Internet, we list the fundamental factors that affect its elasticity, and point out that adaptive architecture is the potential development direction for the future Internet and discuss the adaption from the following aspects: the Controllability, the Manageability, the Scalability and the Trustworthy. Moreover, we survey the work about key technologies and architectures of the Adaptive Future Internet in detail, and analyze their advantages and the com- patibility. As a result, we present an Adaptive Future Internet Framework (AFIF) which gives a reference for study on Future Internet.
