Local customer internetworking scheme in passive optical networks

In this paper, we present a novel bandwidth-efficient passive optical network (PON) architecture with local customer internetworking capability. It provides high bandwidth efficiency for delivering both upstream and local internetworking data. It is shown through simulation that the throughput and delay performance of the proposed PON is improved compared to conventional PON based on time division multiple access (TDMA), especially under heavy offered load. The proposed PON system is believed to be an economically feasible and implementable solution of a new PON system with optical internetworking capability among local subscribers.
