This paper proposes a framework for a flow-based network traffic monitoring of building automation and control networks. Current approaches to monitor special environment networks are limited to checking accessibility and a state of monitored devices. On the other hand, current generation of flow-based network monitoring tools focuses only on the IP traffic. These tools do not allow to observe special protocols used, for example, in an intelligent building network. We present a novel approach based on processing of flow information from such special environment. To demonstrate capabilities of such approach and to provide characteristics of a large building automation network, we present measurement results from Masaryk University Campus.
