“…Most recent research [5][6][7][8][9] focused on distributed DBA at a particular energy efficiency by integrating sleep and dozing on ONU. Reference [10] proposed linear and nonlinear bandwidth prediction models to service non-uniform bandwidth requests originating from users. Interleaved polling with adaptive cycle time to enhance bandwidth allocation in EPON was proposed in [11].…”

“…Modern optical access technologies play a crucial role in meeting these rising demands. The end-to-end optical-fiber-based connection from a central office to the home, known as Fiber-to-Home (FTTH), has become a reality in the last decade thanks to the emergence of passive optical networks (PONs) [2]. FTTH PON has experienced notable growth in bandwidth support and improved service quality [3], and research on its bandwidth and energy efficiency has become a significant focus VOLUME 11, 2023 This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 License.…”

Energy-Efficient Sleep-Aware Slicing-Based Scheduler (SA-SBS) for Multi-Operators Virtualized Passive Optical Networks

Due to the long reach of the next-generation passive optical network (PON), the idea of sharing infrastructure between multiple PON operators has emerged to reduce capital and operational expenditures. However, the standard transmission convergence layer requires an independent virtual bandwidth management process for each operator. Each operator uses a virtual dynamic bandwidth assignment (vDBA) for upstream bandwidth control. An additional bandwidth scheduler is required to create a single physical bandwidth map (phyBW-map) with non-overlapping time slots for each optical network terminal (ONT) or optical network unit (ONU) in the upstream frame. However, the existing slicing-based scheduler (SBS) using dynamic bandwidth assignment schemes does not perform well with the cyclic sleep process (CSP) for energy conservation in PON due to inefficient utilization of the residual bandwidth of the asleep ONUs of an operator. This work introduces an energy-efficient sleep-aware slicing-based scheduler (SA-SBS) for the multi-operator scenario of ten gigabit-capable symmetric PONs (XGS-PONs). Our approach (SA-SBS) achieves 7-10% better energy savings than the existing slicing-based scheduler (SBS) without compromising upstream delays and delay variance. Moreover, we demonstrate that our scheme outperforms the original SBS, resulting in an average delay(s) reduction of up to 28.5% for operators 1, 2, 3, and 4, respectively. Our findings can significantly improve the energy efficiency and latency performance of virtual PONs in multi-operator scenarios, paving the way for a sustainable and reliable communication infrastructure.INDEX TERMS Bandwidth assignment, bandwidth efficiency, energy efficiency, MT-vPON, vPON.
