摘　　要：信息技术(IT)环境中采用了诸多不同方法来确定网络性能,其中有些方法可以为工业控制系统(ICS)环境提供有关网络性能和确定性的有价值信息。延迟、流通量、抖动等网络指标的基本概念适用于ICS环境,但依据不同的ICS网络结构和通信协议的确定性要求,它们的重要性通常不尽相同。重点讨论评估ICS网络时所使用的方法和工具,包括ICS环境下影响设备性能的一些因素,当前常见监控系统之间存有的一些差异,并分析了网络结构下层ICS网络性能时使用到的技术。Many different methods have been used in the information technology environment to determine network performance.Some of the methods can provide valuable information about network performance and determinism for industrial control system(ICS)environment.The basic concepts of network index of latency,throughput and jitter,etc.are suitable for ICS environment.However,they take on different importance based upon the determinism requirements of different ICS network architecture and communication protocols.The methods and tools used to evaluate ICS network performance are discussed with stress,including some factors that affect device performance in an ICS environment,some of the differences among monitoring systems currently,and techniques used to evaluate ICS network performance at the lower layers of the network architecture.
