Online scheduling algorithms incur no idle time problem but with less bandwidth efficiency, while offline scheduling algorithms focus on bandwidth efficiency but with idle time overhead. Although a just-in-time (JIT) scheduling algorithm for multi-channel Ethernet passive optical networks (EPONs) has been proposed to increase the bandwidth efficiency(More)
An EPON DBA algorithm can be separated into inter-ONU scheduling and intra-ONU scheduling. Intra-ONU scheduling may not predict the bandwidth allocation result from inter-ONU scheduling and waste the allocated bandwidth due to the unused slot remainder (USR) problem. In this study, we propose an active intra-ONU scheduling to make the result from the(More)
