This paper addresses the issue of bandwidth allocation over Ethernet passive optical networks (EPONs). We develop a state space model to evaluate the controllability of available bandwidth allocation schemes. We show that the predictor-based scheme is completely controllable when the loaded network traffic changes dynamically, while other schemes are either partially controllable or uncontrollable.
