Abstract: Most research works related to dynamic wavelength bandwidth allocation in a time- and wavelength-division–multiplexed passive optical network are based on bin packing algorithm and present many advantages in terms of bandwidth utilization and energy efficiency. However, delay performance can be significantly degraded by frequent wavelength changes. In this paper, we propose a delay-aware dynamic wavelength bandwidth allocation algorithm. First, we theoretically analyze queuing delay corresponding to the tuning time, decision cycle, and the number of optical network units. And then, we show that the queuing delay is decreased by setting the limit value of the number of optical network units in a wavelength channel. In addition, we derive the threshold ratio of the tuning time to the decision cycle as 0.004.
