多粒度光交换网络中的一种波长/波带共享转换池结构

鉴于目前光网络整体成本较高，波长转换器利用率较低的缺点，在研究现有的多粒度光交换结构的基础上!提出了一种共享波长/波带转换器的方案。该方案的技术特点在于：在波带交换矩阵和波长交换矩阵之间增加了一个共享转换池，光纤中需要进行转换的波带和波长都进入共享转换池，共享使用转换池中的波长/波带转换器进行转换。实例表明：该方案能够使光网络中波长转换器的数量大幅度减少，在降低了光网络成本的同时提高了波长/波带转换器的资源利用率。

Architecture of wavelength/waveband sharing conversion pool for multi-granularity optical switching networks

Based on multi granularity optical cross-connect, a scheme that shares wavelength/waveband converter is proposed to decrease the total cost of the optical networks and improve the utilization of wavelength converters. The technical feature of this scheme is adding a sharing conversion pool between waveband switching matrix and wavelength switching matrix to share waveIength/waveband converts. The example in this paper shows that the great ad- vantage of the scheme is to dramatically reduce the number of wavelength converters in the optical networks, decreasing the cost of optical networks while raising the utilization of the resources.
