摘　　要：当前网络流量急速扩张且愈发多样化,减少网络能耗变得日益重要,需要从整体架构上对传统网络进行改革。通过介绍软件定义网络与网络功能虚拟化在信息通信技术中的应用前景,在典型可编程网络架构下,以典型南向接口OpenFlow协议为基础,分别对数据层与控制层可编程关键技术进行探讨,并提出可编程转发设备的平滑演进、业务与资源抽象、协议扩展与流表优化、控制层架构扩展、节能策略研究、北向接口分层设计方案,为可编程网络在节能方面的应用提供了一定的理论基础。Today internet traffic is rapidly exploding and becoming more varied and complex. Meanwhile, reduction of energy consumption is becoming a major concern. The reform from the overall network architecture is required. The prospect of using network function virtualization（NFV） and software defined network（SDN） in information communication technology were introduced, with key technologies in the data layer and control layer respectively discussed, based on a typical programmable network architecture and a typical kind of southbound interfaceOpen Flow protocol. The smooth transition to programmable forwarding devices, abstraction of traffic and resource, extension of protocols and optimization of f low tables, extension of the control layer architecture, research on energy policies and hierarchical design scheme of northbound interfaces were put forward, which provided the theoretical basis for the application of programmable network in energy saving technology.
