摘　　要：传统的DSS(Distributed Satellite System,分布式卫星系统)网络一般将控制和数据转发功能集中设计在同一网络设备中,使得网络设备设计复杂,网络可重用性差,成本较高。本文基于提高DSS网络的可重用性、高效性和灵活性的目的,采用了将DSS网络控制和数据转发功能分离的方法,通过将DSS、天基移动通信网络和基于OpenFlow的SDN(Software Defined Network,软件定义网络)技术结合起来,提出了一种基于OpenFlow的SDSN(Software Defined Satellite Network,软件定义卫星网络)架构设计方案。通过使用GEO天基系统作为DSS的控制层面,从而和数据层面分离,提高了DSS网络的可重用性、高效性以及灵活性。The traditional network design of DSS network usually centered control and data forwarding functions together in the same network equipment, which makes the design of DSS network equipment complex, the reusability of network poor and the management cost higher. In order to improve the reusability, efficiency and flexibility of DSS network, the method of separating the control function from the data forwarding function was used in this paper. By combining DSS, space-based mobile communication network, and the SDN technology based on OpenFlow together, SDSN（Software Defined Satellite Network） architecture based on OpenFlow is put forward. By using GEO space-based system as the control plane of DSS, the control plane can separate from the data plane, which improves the reusability, efficiency and flexibility of DSS.
