We propose a new dynamic bandwidth allocation (DBA) method for long-reach passive optical networks that can reduce the upstream latency. With this method, an optical line terminal allocates bandwidth to long-distance (up to 100 km) optical network units (ONUs) with a transmission request prediction and reduces the latency of the long-distance ONUs. This has(More)

However, streaming IPTV over a network is challenging as the data rate of a video streaming varies with scene, time, frame-rate, and encoding.
