Abstract
We analyze the dynamic bandwidth allocation (DBA) scheme over Ethernet passive optical networks (EPONs). Our focus is on the non-linear predictor-based DBA (NLPDBA), which outperforms other existing schemes with higher bandwidth utilization and shorter packet delay. We establish a system model to evaluate the controllability of NLPDBA. Analytical results show that NLPDBA maintains the EPON system controllability even when the loaded network traffic changes drastically. Our analysis suggests a straightforward framework to design the DBA scheme that would enable a completely controllable access network.
