摘要：
The time-division multiplexed passive optical network is seen as a candidate for converged fronthaul networks in 5G, which requires low latency and high capacity. In this paper, a hybrid dynamic bandwidth allocation (DBA) scheme for converged fronthaul that combines a status reporting DBA and a cooperative DBA is proposed. Different deployment scenarios and operating conditions in a 10-Gigabit-capable PON (XGS-PON) system are investigated using the OMNeT++ network simulator. The performance of the proposed hybrid DBA is evaluated in terms of average upstream delay and percentage of frame loss meeting a 140 mu s queuing delay requirement for fronthaul traffic. Simulation results show a zero-frame loss for fronthaul traffic in all scenarios using the proposed hybrid DBA which is not achievable using only the status reporting DBA, confirming the advantages of the proposed hybrid DBA.
