Exploring convergence for SCADA Networks

This paper describes the design and implementation of the CONES (COnverged NEtworks for SCADA) realtime middleware toolkit aimed at supporting convered SCADA networks. CONES provides 1) host based process management, 2) network resource management and 3) host based network resource management. These capabilities collectively provide a basis for convergence of SCADA networks while ensuring that isolation and timeliness properties of all SCADA applications (e.g., protection, monitoring and maintenance) are supported as per the requirements of those applications. We provide an architecture, an advanced prototype implementation and extensive experimentation results to demonstrate the feasibility of CONES.
