摘　　要：光缓存和波长变换是解决光分组竞争的有效方法。提出一种称为FCOB的新型光分组交换节点结构,它使用固定波长变换器和输出式光缓存来解决光分组的竞争。针对FCOB交换结构,还提出一种有效的竞争控制算法。最后,使用仿真实验对FCOB的性能进行了评估。仿真结果表明,虽然使用的是固定波长变换器,但FCOB交换结构仍具有良好的性能。Optical buffer and wavelength conversion are effective method to resolve the optical packet contention. A novel optical packet switch, i. e. , optical packet switch with fixed wavelength converter and output buffers（FCOB）, has been proposed. In FCOB, fixed wavelength converters and output optical buffers are used to resolve optical packet contentions. In addition, an effective contention control algorithm for FCOB has been also proposed. At last, the performances of FCOB have been evaluated by simulation experiments. Simulation results show that FCOB can achieve good performance though fixed wavelength converters are adopted.
