摘　　要：软件定义网络(SDN)将网络控制平面与底层的转发设备解耦,为新型互联网体系结构研究提供了新的实验途径。电子信息等相关专业教学亟须基于SDN的网络实验和仿真案例。构建SDN视频跨域专网实验平台,采用PIE算法对专网进行网络流量控制实验设计。结合通信网络教学常用的ns-3仿真软件进行了实验仿真,测试了典型业务场景的网络性能。仿真结果表明,PIE算法具有在网络拥塞时改善端到端时延的能力。Software-defined networking(SDN)decoupling the network control plane from the underlying forwarding equipment provides a new experimental approach for the research of the new Internet architecture.The teaching of electronic information and other related majors is a urgent need of network experiment and simulation case based on SDN.A video cross-regional private network experiment platform is built,and PIE algorithm is used to simulate the network traffic control of private networks.Combined with ns-3 simulation software commonly used in communication network teaching,the experimental simulation is carried out to test the network performance of typical business scenarios,and the simulation results show that the PIE algorithm can improve the end-to-end delay in the case of network congestion.
