“…DBA schemes that estimate the amount of new packets arriving between two consecutive polling instants and grant ONUs a larger window size based on this estimate were proposed in [15,16] and were shown to improve performance over the basic IPACT scheme. A polling protocol for EPONs called transmission upon reception was introduced in [17]; the protocol ensures collision-free transmission while taking into account fairness considerations in allocating bandwidth.…”

Abstract-We present a simple yet effective enhancement to the operation of the Ethernet passive optical network (EPON) multipoint control protocol (MPCP) for wavelength division multiplexing (WDM) EPON. The enhancement, inspired by our earlier work in a related but different context, allows the optical line terminal (OLT) to perform look-ahead scheduling on each of the upstream channels. The look-ahead operation is fully compatible with the existing standard and may be implemented via software updates to the OLT without affecting the operation of optical network units in EPON. The look-ahead enhanced MPCP achieves significant performance gains across a wide range of traffic loads and opens up new opportunities for the design of sophisticated dynamic bandwidth algorithms to support advanced quality of service capabilities.

“…This research proposes dynamic Quantum allocation method based on Cousin Fair Hierarchical Deficit Round Robin Dynamic Bandwidth Allocation (CFHDRR DBA)) [9] [21], which can keep cycle time stable through Quantum dynamic allocation. This method also makes bandwidth more efficient by modifying the ONU single round translimit of the original cousin-fair hierarchical deficit scheduling method.…”

With the development of ICT (Information and Communication Technology), how to use EPON for ensuring an effective and fair bandwidth allocation as well as the quality of service has become an important issue. Our research is based on Cousin Fair Hierarchical Deficit Round Robin Dynamic Bandwidth Allocation (CFH-DRR DBA), which applies the concepts of hierarchical scheduling to reduce extra actions in information controlling and queue switching and DRR (Deficit Round Robin) to attain the goal of cousin fairness. Our research proposes three additional modules to CFHDDR DBA: (1) an admission control module, which limits the sum weight of QoS-controlled flow; (2) a weight partition module, which isolates the sum weight of other interfering flows from QoS-controlled flows; and (3) the quantum adaptation module, which minimizes the access time of QoS-controlled flows through Quantum distribution. With the help of OMNet++ simulation software, this research presents the improvement of CFHDRR by introducing dynamic DDR Quantum. In addition, it proposes admission control and bounded weight to keep the sum of flows within service capacity. The simulation result shows that, while keeping CFHDRR's fairness, the queuing delay is reduced and the cycle time is effectively controlled so that the packet delay of QoS-controlled flows is minimized and QoS of real-time multimedia in EPON is fairly ensured.

“…In order to accommodate the huge demands of subscribers resulting from the explosive growth of the Internet and numerous high-broadband applications, many studies [1,2,4] on EPON have been discussed. In general, an EPON architecture based on tree topology is a point-to-multipoint fiber optical network, which consists of an optical line terminal (OLT), a 1:N passive star coupler (or splitter/combiner) [2], and multiple optical network units (ONUs) which share an optical fiber between the passive star coupler and the OLT for data upstreaming [2,3].…”

“…Based on limited service, constant and linear credit services are proposed [3]. Basically, these services take into account newly arriving packets from subscribers during the interval between the current upstream end time and the next upstream start time of a particular ONU [3,4]. The constant credit service allocates the requested bandwidth and fixed credits as additional bandwidth.…”

Abstract. Ethernet passive optical network (EPON) has been considered to solve the last mile bottleneck problem. In an effort to accommodate the explosive bandwidth demands from subscribers, the optical line terminal (OLT) efficiently divides and allocates time slots for data upstream to all optical network units (ONUs) in EPON. This technology is expected to be a core in the future fiber-to-the-home/-office/-curb (FTTH/O/C). We study previous algorithms for dynamic bandwidth allocation (DBA) in interleaved polling with adaptive cycle time (IPACT). For effective bandwidth allocation of the uplink channel, we propose an adaptive window-tuning algorithm (AdWin) based on the excessive bandwidth. This algorithm not only satisfies bandwidth demands of ONUs within the possible scope, but also seeks fairness among ONUs. The comprehensive computer simulation results indicate that the proposed scheme is up to 94% and 94% lower than previous schemes in terms of average packet delay and average queue size, respectively. It also demonstrates up to 86% improved performance in regards to packet loss ratio.
