Next-generation Passive Optical Network (PON) has been widely considered as a cost-effective broadband access technology. With the ever-increasing power saving concern, energy efficiency has been an important issue for its operations. In this paper, the authors present a novel sleep time sizing and scheduling framework that satisfies power efficient bandwidth allocation in PONs. They consider the downstream links from an Optical Line Terminal (OLT) to an Optical Network Unit (ONU). The ONU has two classes of traffic, control and data. Control traffic are delay intolerant with higher priority than the data traffic.
