摘　　要：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％．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.
