In order to improve the performance of Gigabit Passive Optical Network(GPON) systems, a novel dynamic bandwidth allocation(DBA) scheme called P-DBA based on traffic prediction for GPON is proposed, which can better meet the optical network's technical requirements of high bandwidth, low delay and low packet loss rate. Using the high-order moving average model, P-DBA scheme predicts the amount of high-priority traffic arriving during the waiting period, as a basis for bandwidth allocation, so as to ensure the performance of high priority services. Simulation results show that the P-DBA scheme proposed in this paper has good performances on latency and packet loss rate.
