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.

“…However, the efficiency of bandwidth utilization with the NSR method is lower than with the SR method [7]. IPACT [8] can reduce the GPT owing its simple SR-DBA method, but latency increases as the number of linked up ONUs increases because of the adaptive DBA cycle depends the amounts of requests from the ONUs. In addition, priority control is beyond its scope.…”

Implementation of ultra-low latency dynamic bandwidth allocation method for TDM-PON

This paper proposes a new dynamic bandwidth allocation (DBA) method with low latency for campus area networks (Campus-LANs) and mobile fronthaul (MFH) based on time division multiplexing passive optical network (TDM-PON). These network systems require low latency of under 100 µs and priority control. The proposed method involves only two steps for allocation. The DBA cycle value, which is proportional to the latency, can be minimized because this method is very simple and appropriate for hardware (H/W) implementation. We implemented the proposed DBA on 10G-EPON MAC SoC and evaluated the allocation results and the latency on the 10G-EPON system. Our DBA offers ultra-low latency of 60 µs with priority control.

“…However, it is inefficient because traffic nature is not homogeneous and not continuous [4][5][6]. In this way, algorithms which distribute the available bandwidth in a dynamic way, called Dynamic Bandwidth Allocation algorithms (DBA), are necessary to adapt the network capacity to traffic conditions by changing the distribution of the bandwidth assigned to each ONU depending on the current requirements [5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…This behaviour causes a waste of time during the waiting period [7][8][9][10]. In polling schemes, the OLT allocates bandwidth to each ONU for the next cycle before the last packet of the previous one arrives, resulting in efficient upstream channel utilization [6,[11][12][13]. The algorithm called Interleaved Polling with Adaptive Cycle Time (IPACT) is one of the most efficient polling algorithms in which ONUs are polled individually in a round robin fashion [11].…”

EPON bandwidth allocation algorithm based on automatic weight adaptation to provide client and service differentiation

et al. 2008

In this article, a new dynamic bandwidth allocation algorithm for the upstream channel of Ethernet Passive Optical Networks, called DySLa, is proposed not only to provide service differentiation but also to offer subscriber differentiation. In contrast to previous methods in which the performance of each class of service is not insured, DySLa is continuously evaluating the mean packet delay and guarantees that the highest priority services fulfil the packet delay requirements in the access network for every type of client. Simulation results show that DySLa can maintain both the mean packet delay and packet loss ratio below the maximum upper bounds permitted for the most sensitive services of every class of customer. Moreover, DySLa outperforms other dynamic bandwidth allocation algorithms which provide service and client differentiation and it makes a fairer bandwidth distribution than those methods.
