This study is about a prediction approach for our previous dynamic bandwidth allocation algorithm for Ethernet Passive Optical Networks (EPON). Our previous work (hcDBA) based on half cycle timing for bandwidth allocation. That can be handled as a middle way between online and offline bandwidth allocation schemes. Prediction for bandwidth allocation is worked on decrease the delay of end-to-end transmission. However the versatile nature of data traffic, prediction algorithms have a handicap to give a better solution in classical approaches. In this study prediction approach integrated to hcDBA algorithm to get better end-to-end delay values
