This paper proposes a new dynamic bandwidth allocation (DBA) method with low latency for campus area networks (Campus-LANs) and mobile fronthaul (MFH) based on time division multiplexing passive optical network (TDM-PON). These network systems require low latency of under 100 µs and priority control. The proposed method involves only two steps for allocation. The DBA cycle value, which is proportional to the latency, can be minimized because this method is very simple and appropriate for hardware (H/W) implementation. We implemented the proposed DBA on 10G-EPON MAC SoC and evaluated the allocation results and the latency on the 10G-EPON system. Our DBA offers ultra-low latency of 60 µs with priority control.
