Novel dynamic flow allocation scheme over ethernet passive optical networks

Abstract

A new dynamic flow allocation scheme to guarantee quality of service and more stabilized performance is proposed, replacing an Ethernet passive optical network. This new scheme improves a priority-based access network, converting it to a flow-based access network with a new access mechanism and scheduling algorithm. With this new scheme, a network service provider can provide upper limits of transmission delays by the flow. The modeling and simulation results with mathematical analyses obtained by this scheme are also provided. (c) 2007 Society of Photo-Optical Instrumentation Engineers.
