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 private network based on IP technology is object-oriented and service, flexible and convenient to use, but the service quality is difficult to guarantee. Because of the real-time, reliability and security requirements of information transmission in private networks, in order to verify the performance of the designed private network, the simulation and simulation of private networks using OPNET simulation tools have been made, and the delay in IP private networks , Delay jitter and packet loss rate with the type of business, network traffic load, different transmission rates and circuit error rate, and the experimental data were analyzed, and finally for the IP private network business configuration and flow control given Suggestion
