Ethernet passive optical network (EPON) is becoming one of the best schemes in the broadband access network as it combines the Ethernet and passive optical network technology. In order to avoid collision in upstream EPON, Universal Dynamic Bandwidth Allocation (UDBA) algorithm is proposed in this paper where it can support a universal priority in the entire EPON system. For proof-of-concept, the UDBA algorithm is implemented inside a proposed peripheral interface controller (PIC) based EPON testbed in order to evaluate the communication protocol involved. To the best of our knowledge, this is the first time PIC is being used in EPON testbed for this purpose. To ensure that the testbed is valid, we compare the result that we achieved via testbed with the results achieved via MATLAB simulation in terms of throughput, delay and fairness. The simulated results show a good agreement with the experimental with some minor expected differences. � 2010 PACS.
