摘要/Abstract

摘要：

针对当前互联网中存在的2个亟待解决的问题：OTT（over the top）流量占用大量网络带宽以及信息高度冗余，提出了一种具有差异化服务能力的未来网络体系架构——服务定制网络（SCN,service customized net-working）。SCN基于软件定义网络设计，继承了其数据控制分离以及网络可编程的主要特点，并针对当前互联网中的问题，增加了网络虚拟化能力以及内容智能调度能力。通过构建具有不同等级服务能力的虚拟网络，SCN可以避免OTT业务大量占用带宽。同时，通过信息资源智能有序调度，SCN可以消减信息冗余。在小规模真实网络平台上进行的实验结果表明，SCN确实具备为不同用户提供差异化服务能力以及有效减少信息冗余的能力。

Abstract:

Today's Internet faces many challenges,two of which need to be addressed urgently.One is that most band-width is taken by OTT services,and the other one is that the content in the Internet is highly redundant.To address these two problems,a novel future Internet architecture,named as service customized networking (SCN),is proposed to pro-vide differentiated services.SCN is designed based on the software-defined networking (SDN) technology.It inherits the two advantages of SDN,that is,separation of control and data plane and programmable networking.Besides,SCN adds the function of network virtualization,and intelligent content scheduling.SCN avoids OTT services taking too much bandwidth through employing the network virtualization technology to provide differentiated services.Besides,SCN ef-fectively eliminates content redundancy by intelligent content scheduling.The results of experiments conducted on a real small-scale testbed indicate that SCN indeed provides differentiated services for different users and largely reduces con-tent redundancy.

Key words: future internet architecture, service customization, differentiation, information redundancy, network virtual-ization
