Dynamic Bandwidth Allocation Algorithm for Ethernet Passive Optical Networks Based on Traffic Prediction

In this paper, an algorithm based on traffic prediction is proposed, in bid to predict instantaneous traffic in ONU, guide higher-priority bandwidth allocation, and avoid "T+2" queuing delay. That is the Dynamic Bandwidth Allocation (Pre_DBA) for EPONs, which also includes a prediction corrected mechanism, to maximize bandwidth utilization. As is verified in the designed simulation, this algorithm, apart from ensuring effectiveness and fairness of the premise, is quite able to alleviate delay and jitter in higher-priority services as well.
