摘　　要：提出了一种周期性的开／关（突发）传输源。它代表了用于ＡＴＭ网络中的漏桶速率控制机制中的输出量。列出了多传输单队列情况下关于缓冲区大小和信元丢失可能性的条件，并且给出了严格的证明。这些条件可以和有关分配带宽和决定缓冲区大小的算法一起运用以确保缓冲区和带宽分配处于最好情况和最坏情况的需要之间。 An exact analysis of cell loss for periodic on off traffic sources is presented in this paper. Periodic on off traffic sources arerepresentative of output traffic from leaky-bucket rate-control mechanisms. Equations for buffer sizing and cell loss probabilities aredeveloped and proved for a single queue with multiple traffic sources. These equations can be used in concert with probabilistic methods to ensure that buffer and bandwidth allocations are made between the best-and worst-case requirements.
