Scene based M/G/1 queuing model of VBR video traffic

To guarantee quality of service (QoS) in future integrated service networks, traffic sources must be characterized to capture the traffic characteristics relevant to network performance. Recent studies reveal that multimedia traffic shows burstiness over multiple time scales and long-range dependence (LRD). Its burstiness and self-similarity make it hard to control and guarantee QoS, so analysis of its queuing behavior attracts much interest and attention. A new scene based M/G/1 queuing model is put forward to analyze the queuing behavior of video streams in the network buffer. Integrated with the scene length distribution, the variance of scene size and the average bit rate of GOPs, the proposed model can accurately describe the queuing behavior of video traffic overall.
