Abstract
Supervisory Control and Data Acquisition (SCADA) System which is a member of the set of Industrial Control System (ICS) is notable for control and monitoring of national critical infrastructure such as electricity supply network, oil/gas system, railways system and all those critical infrastructure that are geographically spread. This necessitates the need for a rem control centre where information from other locations are dispatched to, after initial processing at the fields (remote locations). The focus of the paper is to examine the peculiarity of SCADA System protocols and the requirements for its performance model. It has been observed that while hundreds of papers have been written on SCADA System security, very few studies have delved into issues of its peculiar protocols talk less of their performance. A general introduction to protocol performance is made followed by review of existing performance models for the TCP/IP Protocols suite used for the internet. Some protocol performance evaluation and metrics are then considered. The difference between the demands of data flow in TCP/IP protocols suite and that of the SCADA System protocol reference model are clearly depicted in figures 4 and 5. With the obvious variation in data flow demands of the two, we are able to highlight the vital elements required of SCADA System Protocol performance model.
