Abstract

This work proposes a novel blind void (idle periods) filling in Long-Reach Ethernet Passive Optical Networks (LR-EPONs) namely Size Controlled Batch Void Filling (SCBVF). We emphasize on reducing grant delays and hence reducing the average packet delay. SCBVF delay reduction is achieved by early flushing data during the idle time periods (voids) between allocated grants. The proposed approach can be integrated with almost all of the previously reported dynamic bandwidth allocation schemes. SCBVF is less sensitive to differential distance between ONUs and can work well in case of small differential distances compared to previously reported void filling schemes. We support our work by extensive simulation study considering bursty traffic with long range dependency. Numerical results show a delay reduction up to 35% compared to non-void filling scheme outperforming its main competitors that can achieve up to 7% delay reduction.
lr - epon的盲补效果如何?
本文提出了一种新型的远程以太网无源光网络(lr - epon)盲空洞(空闲时间)填充方法,即尺寸控制批量空洞填充(SCBVF)。我们强调减少授权延迟,从而减少平均数据包延迟。减少SCBVF延迟是通过在分配的补助金之间的空闲时间段(空白期)早期刷新数据来实现的。所提出的方法可以与几乎所有先前报道的动态带宽分配方案集成。与先前报道的空隙填充方案相比,SCBVF对onu之间的差分距离不太敏感,并且在小差分距离的情况下可以很好地工作。我们通过广泛的模拟研究来支持我们的工作,考虑了具有长距离依赖的突发交通。数值结果表明,与非空洞填充方案相比,延迟减少高达35%,优于其主要竞争对手,可以实现高达7%的延迟减少。
