In this paper, we design a QoS Guaranteed Dynamic Bandwidth Allocation (QGDBA) scheme for a unique OFDMA-PON architecture. In the scheme, we apply statistical method to dynamically allocate bandwidth, iteration algorithm to fully utilize the frames and United-Priority to guarantee QoS of differentiated services. From the simulation results, we find the scheme can provide efficient bandwidth allocation for the next-generation OFDMA-PON.
