| 摘 要： | 由于液体流模型不能反映实际背景流的突发性及包长分布,基于液体流模型的可用带宽测量技术在突发背景流及多跳链路下测量精度较低.因此,提出了一种基于M/D/1排队模型的高精度可用带宽测量算法FPU(five-packet-unit for available bandwidth measurement).该算法采用五包结构构...

| Abstract: | Most of the available bandwidth measurement technologies are based on fluid model,so those can not get high accuracy in the context of a multi-hop path and burst cross traffic arrival.A novel method of high accuracy available bandwidth measurement called FPU(five-packet-unit for available bandwidth measurement) based on M/D/1 queuing model was proposed.The method adopted five-packet-unit combining with setting the value of TTL,measured the gaps between probe packets before and after bottleneck link respecti... |
