摘　　要：SDN符合未来网络硬件标准化、设备软件化的特征,颠覆了现有的网络架构,其应用、控制、转发相分离的架构设计为网络创新带来了新的活力。本文分析现有应用层流量优化技术ALTO及其与SDN架构融合的优势和可行性,提出基于SDN的ALT0协议优化需求。SDN is corresponding to the standardized hardware and software defined devices, which are characteristics of future network. It overturns the current network architecture and brings agility for network innovation based on the separation of application, control and forwarding. This paper analyzes the existing ALTO and the advantages and feasibility of the merged architecture of ALTO and SDN. Furthermore, the requirements of ALTO protocol based on SDN are proposed.

关 键 词：应用层流量优化 软件定义网络 ALTO扩展
