Executive Summary

The authors investigate Optical Network Unit (ONU) grant scheduling techniques for multichannel Ethernet Passive Optical Networks (EPONs), such as Wavelength Division Multiplexed (WDM) EPONs. They take a scheduling theoretic approach to solving the grant scheduling problem. They introduce a two-layer structure of the scheduling problem and investigate techniques to be used at both layers. They present an extensive ONU grant scheduling simulation study that provides: insight into the nature of the ONU grant scheduling problem and indication of which scheduling techniques are best for certain conditions.
