In this article, a framework for dynamic bandwidth assignment in gigabit passive optical networks (GPONs) employing the Offset-Based Scheduling with Flexible Intervals (OSFI) concept in order to achieve distribution of bandwidth in such networks ensuring not only high system utilization but also clean-cut quality of service differentiation based on the individual demands of user services.Abstract:
This paper introduces a novel framework for dynamic bandwidth assignment (DBA) in gigabit passive optical networks (GPONs) employing the Offset-Based Scheduling with Flexible Intervals (OSFI) concept in order to achieve distribution of bandwidth in such networks ensuring not only high system utilization but also clean-cut quality of service (QoS) differentiation based on the individual demands of user services. In addition, ways to enhance efficiency in the case of next generation long-reach GPONs are discussed. A thorough description of the proposed mechanisms is provided, while the improved system performance is verified using simulations.read more

Comprehensive performance assessment of bipartition upstream bandwidth assignment schemes in GPON
TL;DR: A bipartition DBA (BI-DBA) mechanism in GPON is proposed that divides the transmission cycle time into two groups and adjusts the bandwidth dynamically and has better system performances in terms of the average bandwidth utilization, packet latency, and drop probability.
