摘要： 传统的监控与数据采集(SCADA)系统一般运行在封闭的环境中，外部条件、输入数据量、资源的配置与分配方法一般都是预先已知的，并且在运行过程中很少改变。当前对于SCADA系统的开放性要求越来越高，外部条件、输入数据以及资源利用经常动态变化。针对这一趋势，提出在开放性SCADA系统中的资源分层管理策略，讨论带宽分配策略和处理器利用率，并利用一个实例对策略进行评估。

Abstract: The traditional Supervisory Control And Data Acquisition(SCADA) systems are usually designed for closed environment, input, data and resource, which are availability known at prior and are subject to little change. There is an increasing demand for SCADA systems to be adaptive to open environments where the input data and resources are changeable. In order to adapt such trends, a kind of hierarchical resources management strategy in open SCADA system is proposed based on practices, and bandwidth allocation and CPU utilization are mainly discussed.
