Scheduling Hybrid WDM/TDM Passive Optical
Networks With Nonzero Laser Tuning Time
Jingjing Zhang, Student Member, IEEE, and Nirwan Ansari, Fellow, IEEE
Abstract--Owing to the high bandwidth provisioning, hybrid
wavelength division multiplexing/time division multiplexing
(WDM/TDM) passive optical network (PON) is becoming an
attractive future-proof access network solution. In hybrid
WDM/TDM PON, tunable lasers are potential candidate light
sources attributed to their multiwavelength provisioning capa-
bility and color-free property. Currently, the laser tuning time
ranges from a few tens of nanoseconds to seconds, or even minutes,
depending on the adopted technology. Different laser tuning time
may introduce different network performance. To achieve small
packet delay and ensure fairness, the schedule length for given
optical network unit (ONU) requests is desired to be as short
as possible. This paper illustrates contributions in four main
aspects. First, we show that both preemptive and nonpreemptive
scheduling problems with the objective of minimizing the schedule
