文献 [1]提出了Open LoopShuffleout的ATM交换结构 .它是基于多级自路由、输出排队的Banyan结构 .文献[9]在文献 [1]的基础上构造了多递ATMShuffleout交换结构 .这种Open LoopShuffleout的ATM交换结构的信元丢失率包括三部分 ,其中之一就是网络丢失率πn.文献 [1]计算网络丢失率是在假设任意一级交换单元中每一输出端口的负载相同的前提下进行的 .本文考虑了更一般的情况 ,给出了精确计算网络丢失率的分析模型 ,不仅能够处理随机业务 ,而且还能处理热点业务 .模型分析和仿真的数字结果显示了在热点业务下一些有益的结论 .
Literature [1] proposed the Open LoopShuffleout ATM switching fabric, which is a Banyan fabric based on multi-level self-routing and output queuing. [9] constructed a multi-delivery ATMShuffleout fabric based on [1] The cell loss rate of LoopShuffleout ATM switching fabric consists of three parts, one of which is the network loss rate πn. [1] The calculation of network loss rate is based on the assumption that the load of each output port in any switching unit is the same This article considers the more general case and gives an analysis model that accurately calculates the network loss rate, which not only deals with random services but also handles hot-spot services.The numerical results of model analysis and simulation show that some hot spots Beneficial conclusion.
