摘　　要：提出并分析了一种具有波分复用的光分组交换架构中置入波长转换器的模型,在该结构中每个输入线都共享波长转换器,讨论了在均衡和非均衡条件下,网络丢包率和波长转换器数目的关系,仿真结果表明该模型能在降低丢包率的同时又能减少波长转换器的数目。An architecture model for optical packet switches with wavelength multiplexing, in which the wavelength converters are shared-per-input-line （SPIL）, is proposed and analyzed in this paper. The relationship between packet loss ratio and wavelength converters under the conditions of the balanced and unbalanced traffic is discussed. The simulation results show that this architecture reduce both the packet loss ratio and the number of wavelength converters.
