Bandwidth and delay fairness in Time Wavelength Division Multiplexed Passive Optical Network (TWDM-PON)

Because of its high transmission rate, Time and Wavelength Division Multiplexed Passive Optical Network (TWDM-PON) has become a particular research topic. Due to the wavelength flexibility and multiple user's access, it becomes necessary and imperative to consider the fairness between all the Optical Network Units (ONUs) so that we can improve the quality of service of the users. This fairness includes the bandwidth allocation and the time delay of using a wavelength. We proposed an approach named Bandwidth and Delay Fairness (BDF) algorithm to improve the fairness. Simulation results show that our approach increases the fairness of all the ONUs.
