Fiber-to-the-home (FTTH) is one of the best broadband access solution for the public. In order to support FTTH services, Ethernet passive optical network (EPON) is mainly used. In this book, an intelligent dynamic bandwidth allocation algorithm based on fuzzy logic is proposed to allocate the upstream EPON bandwidth in the FTTH environment to avoid collision. By using fuzzy logic in EPON, it has been proved that the bandwidth is granted as according to the Quality of Service, thus leads to the less unused slot remainder and less delay. Hence, the performance of the system improves significantly.
