Analysis of forwarding equipment delay upper bound by effective arrival envelop

为合理预留带宽资源,研究了转发设备统计时延边界。通过优化流量样本数量和误差概率来构造有效到达包络,并结合线性规划思路,提出一种时延边界分析方法。数值结果与分析显示,基于有效到达包络的时延边界更加准确,系统带宽利用率得到较好改善。

In order to allocate bandwidth accurately, forwarding equipment statistical delay upper bound was explored. Effective arrival envelop was constructed via optimizing traffic sample number and violation probability, the delay upper bound was derived. Numerical result demonstrates the delay upper bound based on effective arrival envelop is much more accurate and system bandwidth utilization can be improved.
