| 摘 要： | 从光网络向透明架构的演进和面向业务的发展趋势出发,介绍了损伤感知的RWA问题的相关研究,通过给经典RWA算法增加对损伤效果的考虑,提出了具有损伤感知能力的动态RWA算法(IBest,IFF,IPack)并进行了仿真验证,结果表明在有损伤的环境下具有损伤感知能力的动态RWA算法既能保持经典算法的优势又在阻塞率上具有优于经典算法的性能。

| Abstract: | Set out from the evolution to all-optical transparent infrastructure and to service-orient characteristic, the researches on impairment-aware routing and wavelength assignment algorithms are surveyed and analyzed. Three new dynamic impairment-aware routing and wavelength assignment algorithms (IBest, IFF, IPack)are proposed through increasing the consideration of physical impairments effect on classic routing and wavelength assignment algorithms. The results from simulation show that the proposed algorithms both can maintain its competitive edge from corresponding classic ones and are superior to the classic ones in blocking probability in realistic circumstance with impairments. |
