概率生成函数 meaning in English
probability generating function
Examples
- In this paper , we study the performance of input - buffered atm switching with window - access scheme and output - grouping architecture . the close - form formulae of maximum switch throughput , mean cell delay and cell loss probability are obtained by probability generating function approach . the accuracy of theoretical analysis is verified by computer simulations and results show that the maximum switching throughput will reach 99 % under random uniform traffic when the window size and the group size are 4 and 16 respectively
本文提出了具有组合的窗口接入和线群输出结构的输入缓冲atm交换网络并对其性能进行了研究.通过概率生成函数方法得到了计算该交换网络最大吞吐率，平均信元时延和信元丢失率的封闭表达式，并通过计算机模拟实验验证了理论分析的精确性.研究结果表明，在随机均匀业务下，当窗口尺寸和输出群尺寸分别为4和16时，最大吞吐率可达到99
