摘　　要：针对当前高性能计算机光互连网络中存在的光缓冲不易实现的问题,提出了一种无缓冲的光互连网络结构BOIN,并在对网络结构进行建模和分析的基础上,研究了网络的吞吐率随不同的输入负载和网络规模而变化的规律,给出了在一定的互连总规模和输入负载下,网络实际吞吐率达到最大值时网络拓扑结构所必须满足的条件。最后用模拟实验证明了这一结果的正确性。Aiming at the problem of implementing optical buffers in the present high performance computer optical interconneetion, a bufferless optical interconnection, named BOIN, is put forward. Based on modeling and analyzing the network topology, the relationship between the network throughput and the offered loads as well as network sizes is studied. Then the condition of maximum throughput of the network in a fixed offered loads and total number of nodes is presented. Finally, the simulation results show that the correctness is confirmed.
