Traditionally, allocating of Ethernet Passive Optical Network (EPON) bandwidth schemes relied on\na centralized architecture where their Optical Line Terminal (OLT) is the sole intelligent device\nwith the capability for the arbitration of bandwidth based on time-division access for the upstream\nshared channel. However, any breakdown in the OLT bandwidth allocation will affect the\nallotment for Optical Network Units (ONUs). Few researches had dealt with a decentralized approach\nfor the EPON and most of the solutions proposed involved additional cost by adding new\ncomplex devices to the original architecture. This paper proposes an intelligent decentralized\nmechanism in EPON that enhances the network performance using intelligent agents specification\nbased on the IEEE 802.3 ah standards in the foundation for intelligent physical agent which is\ncompatible with an Internet Protocol (IP)-based network. Specifically, this paper proposes a novel\ndistributed scheme that supports differentiated services and ensures QoS for both Inter-and IntraONU\nallocation. The proposed mechanism introduces a unique direct communication between the\nONUs supported by identical dynamic bandwidth allocation algorithms running simultaneously in\neach ONU. In addition to being fully distributed, the proposed scheme is asynchronous, scalable,\nand dynamic with flexibility and reliability in handling data, voice and video.
