FIFO交换网络:一种保持信元次序完整性的多路径ATM交换结构

The FIFO Switch:A Multipath ATM Switch Preserving Cell Sequence

本文提出了一种新型的自选路由ATM多路径交换结构，采用虚拟FIFO缓冲器技术，既能保持信元次序的完整性，又避免了螺旋式交换结构中虚拟信元引起的饱和吞吐量、延迟和信元丢失性能的下降．在均匀通信量和非均匀通信量情况下分析了它的性能，结果表明其最大可达到的饱和吞吐量为7／8，延迟和信元丢失率都比螺旋式结构小很多同时，该系统无需内部加速，适于VLSI集成．

This paper presents a new multipath, self-routing ATM switching architecture. Using virtua FIFO biber technology,the proposed multipath switch can preserve cell sequence. Under the uniform traffic pattem, the maximum achievable throughput of this arehitechure is 7/8. The delay and cell loss probability Performance of the prosed switch is investigated under both uniform and nonuniform traffic patterns.
