High-Performance Networked SCADA Architecture for Safety-Critical Systems

This paper discusses some of currently the most challenging problems of SCADA system design, and presents a concept and initial "proof of concept" implementation of a general purpose SCADA intended for high-end applications. Application like this involves millions of data points and demands real-time decision support system on top of SCADA and its communication infrastructure. In addition to memory and processor power constrains, new solution needs to solve problems like data acquisition and data distribution in distributed, networked environment. Some of the basic requirements for implemented SCADA system includes scalability, distributed and reliable networked operation, high capacity/performance in real time, and support to future extensibility of the solution and implemented data model.
