Abstract

A cyclic water-filling EPON (Ethernet passive optical network) DBA(dynamic bandwidth allocation) algorithm and its implementation in an ASIC are described with future improvements. Every cycle, short static gates are generated to collect reports and dynamic gates are generated according to the reports collected in previous cycle. In each cycle, unit length is additively allocated to the ONUs in a cyclic fashion until all the requests are satisfied or no resource is left. Four parallel engines are used to process the requests. As improvements, priority will be considered, and the processing burden will be evenly distributed to the 4 parallel engines in any case.
