| 摘 要： | 为了分析自相似业务流对通用处理器共享（GPS）系统性能的影响,研究了GPS系统性能与业务流自相似参数等因素之间的关系.通过使用分形漏桶的包络曲线对进入GPS系统的自相似业务流进行整形,推导了利用自相似业务流作为输入的GPS系统的队列长度和时延统计上界.数值结果与分析显示,基于分形漏桶的GPS系统性能模型对自相似业务流具有较好的性能.

| Abstract: | In order to analyze the effect of self-similar traffic on the generalized processor sharing(GPS),the relationship was explored between the performance of a GPS system and the parameter of self-similar traffic.The self-similar traffic getting into the GPS system was regulated using the envelope curve of the fractal leaky bucket(FLB).The upper bounds on queue length and delay of the GPS system with self-similar traffic input was derived.Numerical simulations demonstrate that the performance model of a GPS system based on fractal leaky bucket regulators is suited for the self-similar traffic. |

| Keywords: | self-similar traffic generalized processor sharing fractal leaky bucket queue size delay |
