保持控制系统的网络流量质量至关重要；然而，随着新兴的基于ip的技术的出现，这变得更具挑战性。操作员必须不断地监控控制系统中的交通流量状态，并确定系统是否正常运行。要做到这一点，我们必须了解正常交通的特点，并提取边界条件，即阈值，服务质量开始恶化到无法忍受的水平；这有助于区分安全的交通和不受欢迎的交通。作者提出利用网络仿真技术分析基于ip的控制系统的流量行为，并构建灵活的仿真体系结构。我们还通过实现一个示例场景来评估体系结构模型，该场景估计了实验控制系统所需的网络容量
Maintaining the quality of network traffic of a control system is crucial; however, this is becoming much more challenging with the emerging IP-based technologies. Operators must constantly monitor the state of traffic flow in the control system and decide whether the system is functioning properly. To achieve this, we must know the characteristics of normal traffic and extract boundary conditions, i.e., thresholds, at which the quality of services begins to deteriorate to intolerable levels; this helps distinguish safe traffic from an undesirable one. The authors propose to use a network simulation technique to analyze the traffic behavior of IP-based control systems and construct flexible simulation architecture. We also evaluate the architecture model by implementing an example scenario that estimates the necessary network capacity for the experimental control system
