Design and Development of ICMP based Network Monitoring Tool for SCADA

Abstract

This work describes the design and development of architecture for automated network node discovery, monitoring and topology analysis, implemented as an integrated module for the CrompSCADA. The architecture includes functionality for flexible network model assessment, using a method for versatile comparison between off-line database models and real-world models. These models are populated by current node data collected by network sensors. The presented architecture supports – an efficient creation and synchronization of network topology information, accurate recognition of new/ replaced/upgraded nodes, including SCADA specific devices like Xcell RTU (Remote Terminal Unit), IED (Intelligent Electronic Device), and also provides a free replica of existing vendor specific enterprise network management and provisioning systems. An evaluation of the implementation shows evidence of accurate discovery and classification of unmatched hosts in a live network with over 400 nodes, and presents data on performance and scalability levels. The work was carried out at Distribution Automation Research Centre (DARC), Crompton Greaves Global R&D, Mumbai as part of the MoU between Thapar University, Patiala and Crompton Greaves, Mumbai.
