研究具有输入和输出队的ATM交换的缓存器分配策略。文中首先建立了描述交换网络的模型,然后分析了在有限缓存客量下在输入队和输出队中分组的丢失率。分析表明总的丢失率是输入队和输出队容量的复杂函数,因而在总的缓存容量一定的情况下,必存在使丢失率最小的缓存分配方法。最后用数值结果说明了最佳的分配策略。 Research buffer allocation strategies for ATM switching with input and output teams. In this paper, a model describing the switching network is first established, and then the packet loss rate in the input queue and the output queue under limited buffer capacity is analyzed. Analysis shows that the total loss rate is a complex function of the input queue and the output queue capacity, so there must be a cache allocation method that minimizes the loss rate given the total cache capacity. Finally, numerical results illustrate the best allocation strategy.
