As an inexpensive, simple, and scalable solution for broadband access, Ethernet
passive optical networks (EPONs) have the capability of delivering integrated
broadband services to the end users. A critical issue of EPONs is the utility of a
shared upstream channel among the local users, and thus an efficient bandwidth
allocation mechanism is required to facilitate statistical multiplexing among the
local network traffic. In this paper we propose a dynamic bandwidth allocation
scheme, i.e., limited sharing with traffic prediction (LSTP), for upstream channel
sharing over EPONs. LSTP enables dynamic bandwidth negotiation between
the optical line terminal (OLT) and its associated optical network units (ONUs),
alleviates data delay by predicting the traffic arrived during the waiting time
