“…As its creators demonstrated in their simulations, HYRA can adapt to a variety of changes in the network, and represents a significant improvement in the upstream packet delays. In all situations, this algorithm reduced the resulting delay of the upstream packets compared with an algorithm using the pure SR method [8].…”

“…We have developed our XG-PON simulator specially for testing DBA algorithms performance. In the simulator we implemented the static assignment, and three DBA algorithms, namely hybrid reporting allocation (HYRA) [8], gigaPON access network (GIANT) [9], and modified Max-Min [10]. Algorithms were tested for transmission delay and amount of bandwidth waste.…”

“…With this algorithm, the authors try to solve the problem of too much bandwidth being assigned to unused ONUs resulting in no free bandwidth that the DBA algorithm could assign to other loaded ONUs. This problem is mainly solved by introducing a simple, adaptive learning machine called learning automata (LA) [8].…”

Sophisticated dynamic bandwidth allocation (DBA) algorithms can dramatically improve or worsen throughput and delay in whole networks. It is very important to choose the right DBA algorithm. Our work tests static assignment and three DBA algorithms, namely GigaPON Access Network DBA, Hybrid Reporting Allocation, and modified Max–Min Fair. All tests were made on our simulator of ten-gigabit passive optical network DBA specially developed for testing DBA algorithms. The tests verify delay of each optical network unit and amount of waste with bandwidth. This paper describes how the used DBA algorithms work and the processes involved in DBA algorithms.

PONs (Passive Optical Networks) are the most promising networks for the future. In 1998, the first standard of PONs was developed. Since that time, quality of optical transmissions and technologies has been massively improved and today's standards are capable of transferring an enormous amount of data. For example, NG-PON2 networks are able to transfer up to 40 Gbit/s, which means these networks provide subscribers with a symmetric bandwidth up to 10 Gbit/s using 4 different wavelengths. The higher transmission speeds are required, the more sophisticated bandwidth allocation reflecting requirements of each ONU (Optical Network Unit) in real-time is necessary. This article deals with implementation of NG-PON2 networks using OPNET Modeler and simulations of static and dynamic grants allocations. We also present a modification of dynamic bandwidth allocation for increasing the free bandwidth of idle ONU to heavily loaded ONU(s). We propose a simplified NG-PON2 (Next-Generation PON stage 2) network, for example, activation machine for ONUs is not implemented. At present, OPNET Modeler is being used to simulate EPON (Ethernet PON) networks that use a different approach for data transmission. Thanks to its own implementation, basic data transmission in NG-PON2 networks, and simulations of algorithms for dynamic bandwidth allocation can be achieved.
