摘要
针对客运专线信号系统的安全数据网的可靠性研究,使用网络仿真研究方式时需要的背景流量模型,对时下使用较多的理论模型进行了介绍并对实际使用中常用的泊松模型、跟踪文件背景流量模型进行了研究,得出了一种适用于安全数据网仿真中的背景流量模型.并以相邻车站CBI之间的通信为例介绍了实际仿真研究时这一背景流量模型的构建和应用.
For the research of the reliability of security data network of CTCS,a background traffic model is needed. With the study of theoretical models and research of Poisson model and tracking traffic model that widely used now,a background traffic model which is suitable for the security data network of CTCS was proposed. And in case of communication between CBIs in stations next to each other,there is a sample introduced about how to build and use the background traffic model in simulation research.
