In this paper we adopt the Stochastic Fluid Modeling framework for management and control of communication networks and attempt to explicitly model feedback controlled sources. Specifically, the inflow process consists of a feedback controlled source which is modelled as a hybrid automaton (it has both, time-driven as well as event-driven dynamics). This paper derives Infinitesimal Perturbation Analysis (IPA) derivative estimators for the buffer occupancy and throughput with respect to a node
