摘　　要：基于IP技术的专用网络面向对象与服务,使用灵活、方便,但服务质量难以保证。由于专用网络中信息传输的实时性、可靠性和安全性要求很高,为验证所设计的专用网络的性能,通过OPNET仿真工具对专用网络进行建模仿真,得出了IP专用网络中时延、时延抖动和丢包率与业务类型、网络流量负荷、不同传输速率及电路误码率间的关系,并对实验数据进行了分析,最后针对IP专用网络中的业务配置和流量控制给出了建议。The special network based on IP is object and service-oriented, flexible and expedient in use. However, its quality of service is hard to be guaranteed. For its strict requirement of real time, reliability and security this special network is simulated with OPNET, thus to verify the system performance. The relations among between time delay, delay variation, packet loss ratio, service type, traffic load and QoS strategy in IP-based special network are confirmed by simulation results. Meanwhile, the experimental data is analyzed. Finally the suggestion on operation configuration and traffic control in IP-based special network is provided.
