This paper proposes an efficient bandwidth utilization (EBU) algorithm that utilizes the unused bandwidth in dynamic bandwidth allocation (DBA) of a 10-gigabit-capable passive optical network (XGPON). In EBU, an available byte counter of a queue can be negative and the unused remainder of an available byte counter can be utilized by the other queues. In addition, EBU uses a novel polling scheme to collect the requests of queues as soon as possible. We show through analysis and simulations that EBU improves performance compared to that achieved with existing methods. In addition, we describe the hardware implementation of EBU. Finally we show the test results of the hardware implementation of EBU.read more

Dynamic wavelength and bandwidth allocation for supporting diverse customers and prioritized traffic in NG-PON2 networks
Naureen Hoque,Byrav Ramamurthy +1 more
TL;DR: Five different dynamic wavelength and bandwidth allocation schemes for NG-PON2 system are proposed and P-DBH is the most efficient among the five, because this scheme offers the lowest delay for high-priority data and the minimum bandwidth wastage for lower priority ones.
