无缓冲光互连网络的延时性能分析及优化

针对当前高性能计算机光互连网络中光缓冲不易实现的问题，提出一种无缓冲的光互连网络结构BOIN，在对网络结构进行建模和分析的基础上，研究网络的传输延时随不同输入负载和网络规模而变化的规律，给出在一定互连总规模和输入负载下，网络延时达到最小值时网络拓扑结构所必须满足的条件。模拟实验证明了该结果的正确性。

Analysis and Optimization of Delay Performance of Bufferless Optical Interconnection Network

Aiming at the problem of implementing optical buffers in the present high performance computer optical interconnection difficultly, this paper presents a bufferless optical interconnection named Bufferless Optical Interconnection Network(BOIN). Based on modeling and analyzing the network topology, the relationship between the network delay and the offered loads as well as network sizes is studied. The condition of minimal delay of the network in a fixed offered loads and total number of nodes is given out. Simulation shows that the results are right.
