Diversity DBA Technique for Fairly Handling Various Types of EPON ONU

In Ethernet Passive Optical Network (EPON) systems, Dynamic Bandwidth Allocation (DBA), which is based on a queue status request communicated via REPORT messages, is an indispensable function for providing fair and high bandwidth utilization. However, REPORT messages do not always contain the same values even if the same REPORT formats are used under the same queue size conditions because the contents of REPORT messages are not concretely specified and some flexibility remains. In this paper, to solve this issue and improve EPON interoperability, the authors propose the diversity DBA method, which can accommodate various ONUs with different REPORT implementations.
