Abstract
Traditionally, allocating of Ethernet Passive Optical Network (EPON) bandwidth schemes relied on a centralized architecture where their Optical Line Terminal (OLT) is the sole intelligent device with the capability for the arbitration of bandwidth based on time-division access for the upstream shared channel. However, any breakdown in the OLT bandwidth allocation will affect the allotment for Optical Network Units (ONUs). Few researches had dealt with a decentralized approach for the EPON and most of the solutions proposed involved additional cost by adding new complex devices to the original architecture. This paper proposes an intelligent decentralized mechanism in EPON that enhances the network performance using intelligent agents specification based on the IEEE 802.3 ah standards in the foundation for intelligent physical agent which is compatible with an Internet Protocol (IP)-based network. Specifically, this paper proposes a novel distributed scheme that supports differentiated services and ensures QoS for both Inter-and Intra- ONU allocation. The proposed mechanism introduces a unique direct communication between the ONUs supported by identical dynamic bandwidth allocation algorithms running simultaneously in each ONU. In addition to being fully distributed, the proposed scheme is asynchronous, scalable, and dynamic with flexibility and reliability in handling data, voice and video.
Highlights
The increase in worldwide use of the Internet is expected to lead to increased options in distance learning, e-commerce, and communication that are multimedia-based
As a multiservice access network, the proposed architecture should support a multitude of services, i.e., triple play including best-effort data, video stream, and voice
The improved percentage is defined as the gain obtained in the average allocated bandwidth of the proposed IDDBA algorithm compared to EDDBA and IPACT algorithms
Summary
The increase in worldwide use of the Internet is expected to lead to increased options in distance learning, e-commerce, and communication that are multimedia-based. The algorithm used does not need any changes to the existing EPON frame, and only assigns the window information sent by other ONUs to a particular ONU through OLT It is totally in accordance with the (Multi Pint Control Protocol) MPCP protocol of IEEE 802.3 ah standard and requires the addition of some new fields in the report and gate frames. This paper proposes an intelligent decentralized direct communicability scheme between the ONUs-based EPON It is a potential fiber-based communication because of its high speed, cost-effectiveness and scalability supported by a DBA algorithm based on intelligent agents’ concepts, in which the bandwidth implementation assignment excludes the OLT. The proposed distributed EPON scheme is able to support the services that are differentiated and ensures QoS for both Inter and Intra ONU allocation
