Dynamic Bandwidth

Bandwidth allocation is one of the critical issues in the design of Ethernet passive optical networks (EPONs). In an EPON system, multiple optical network units (ONUs) share a common upstream transmission channel for data transmission. To efficiently utilize the limited bandwidth of the upstream channel, a system must dynamically allocate the upstream bandwidth among multiple ONUs based on the instantaneous bandwidth demands and quality of service requirements of end users. This chapter gives an introduction of the fundamental concepts on bandwidth allocation in an EPON system, discusses the major challenges in designing a polling protocol for bandwidth allocation, and presents an overview of the state-of-the-art dynamic bandwidth allocation (DBA) algorithms proposed for EPONs.
