“…In legacy TDM-PONs, a typical upstream scheduling order, i.e., the order implemented in IPACT, is REPORT-GATE-DATA: first, the ONU sends a REPORT message to request US bandwidth; the OLT then responds with a GATE message; and the ONU sends US traffic in the assigned timeslot. The impact of the REPORT scheduling, either at the beginning or at the end of an US timeslot for both online and off-line scheduling schemes, on legacy TDM-PON performance has been investigated [14]. However, when incorporating sleep/doze mode into the operations of a PON system, a scheduling scheme must specify where to insert the sleep period and/or doze period into an existing order of data transmission, REPORT message, and GATE message.…”

This paper proposes an energy-saving passive optical network framework (ESPON) that aims to incorporate optical network unit (ONU) sleep/doze mode into dynamic bandwidth allocation (DBA) algorithms to reduce ONU energy consumption. In the ESPON, the optical line terminal (OLT) schedules both downstream (DS) and upstream (US) transmissions in the same slot in an online and dynamic fashion whereas the ONU enters sleep mode outside the slot. The ONU sleep time is maximized based on both DS and US traffic. Moreover, during the slot, the ONU might enter doze mode when only its transmitter is idle to further improve energy efficiency. The scheduling order of data transmission, control message exchange, sleep period, and doze period defines an energy-efficient scheme under the ESPON. Three schemes are designed and evaluated in an extensive FPGA-based evaluation. Results show that whilst all the schemes significantly save ONU energy for different evaluation scenarios, the scheduling order has great impact on their performance. In addition, the ESPON allows for a scheduling order that saves ONU energy independently of the network reach.

This article presents a design of a database model used to gather and analyze data frames transmitted over gigabit passive optical network (GPON) in the downstream direction. An issue with this kind of system is the difficulty in analyzing a transmission on the optical part which is caused by the difference among devices using Ethernet frames technology and passive optical network technology with usage gigabit encapsulation method. In this article, a principle of the downstream direction is described. Next, the design of the database model for the analysis of transmitted data is discussed. Based on the design and implementation of the database, a script capable of processing data gathered by a programmable network card is proposed. The script for physical layer operation, admission, and maintenance (PLOAM) messages analysis is written in the Python programming language.

“…Some schemes that order the polling of ONUs [13] or propose the transmission of a REPORT message before the DATA message [6,36] have been proposed, but they do not break cyclic bandwidth allocation and their effect-particularly for online algorithms-is negligibly small [40]. Moreover, they require minor changes in the scheduling order or in the way a REPORT is appended and can always be used in conjunction with the other algorithms.…”

Several dynamic bandwidth allocation (DBA) algorithms have been proposed for long-reach passive optical networks (LR-PONs). The gains in the current protocols, however, are incremental and limited to a specific range of loads. Using an analytical framework, we first examine the main sources of performance degradation specific to LR-PONs. From this, we conclude that there is a large scope for improvement in the performance by using an optimal cycle length, which is not influenced by reach, and which polls users according to their reported load while providing opportunities for pre-granting bandwidth at the optical network units. The fraction of bandwidth that is pre-granted should be decreased with load. To tailor these optimal design concepts in a DBA algorithm, we propose Synergized-Adaptive Multi-GATE polling with Voidfilling (S-AMGAV), which reduces both the delay bound and packet loss rate by at least 50% when compared to the stateof-the-art DBAs like interleaved polling with adaptive cycle time (IPACT), IPACT with grant estimation (IPACT-GE), multi-thread polling (MTP), double phase polling (DPP), gate driven (GD), and AMGAV. S-AMGAV also maintains simplicity of the protocol while removing bandwidth inefficiencies prevailing in the existing protocols. We verify the usefulness of the algorithm through both analytical modeling and simulations.
