摘要

摘要: ATM网络中突发源可用间断贝努里过(IBP)描述。用稀疏过程理论得到IBP的概率母函数,提出了一种迭代方法计算IBP的概率分布,并就突发源的等价描述进行了讨论。提出了用IBP可近似描述突发源经漏桶后的输出过程,通过计算机仿真验证了这种近似是比较精确的。对如何用IBP更加精确地描述漏桶的输出过程作了进一步讨论。对漏桶算法的平滑功能作了定量分析。

Abstract: In ATM networks, bursty sources can be described as the Interrupted Bernoulli Pro-cess(IBP). With the use of the thin process theory, the Probability Generating Function(PGF) of the IBP is obtained. An iterative algorithm, which can be used to calculate the IBP probability distribution, is presented. The bursty source s equivalent description is discussed. It is proposed that the leaky bucket output process can be approximately described as IBP. The accuracy of the analytical results has been largely validated by means of the simulation approach. Moreover, how to improve its accuracy is discussed. The smoothing function of the leaky bucket algorithm is quantitatively analyzed.
