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。
The burst source available in ATM networks is intermittent Benuirin (IBP) description. The sparse process theory is used to obtain the probability parent function of IBP. An iterative method is proposed to calculate the probability distribution of IBP, and the equivalent description of the burst source is discussed. The IBP can be used to approximate the output process of the burst source after the leaky bucket. The computer simulation shows that this approximation is more accurate. How to use IBP to describe the output of the leaky bucket more precisely is discussed further. The smooth function of the leaky bucket algorithm is quantitatively analyzed.
