摘要 针对波分复用(WDM)光网络在实现端到端业务链接时的波长连续性限制问题,提出了对光网络进行稀疏多光纤配置的方法。通过分析发现:稀疏多光纤配置能够使整个网络的性能受波长连续性限制的影响得到明显改善;具有稀疏多光纤配置的光网络长链路建链阻塞概率在全网阻塞率中的比例要高于使用相同数目波长转换器的光网络,这说明,波长转换器对于光网络的长链建链仍具有一定的优势。 Wavelength-routed all-optical networks are considered to be candidates for the next generation wide-area backbone network, in such networks, the wavelength continuity constraint plays an important role because it reduces the performance of the networks greatly. Since wavelength converters are expensive devices,we propose a sparse multi-fibre link configuration algorithm to improve the performance of networks without wavelength converters. Simulation shows that the proposed configuration can impact the influence of wavelength continuity constraint.
