| 摘 要： | 光网络中,路由与波长分配(RWA)算法是最优化网络性能的核心问题之一,传统的RWA算法都假设光网络的物理层状态是理想的,即不存在光信号传输损伤的问题.通过对这个缺陷的分析,将光信号的传输损伤问题充分考虑到路由与波长分配算法中,从算法的角度来实现对光信号的传输保护,这样做不仅能有效防止业务的物理损伤阻塞,还能极大地提高光网络的性能.

| Abstract: | In optical network,the routing and wavelength assignment algorithm is one of the key problems in optimizing the network performance.The traditional RWA algorithms are typically designed around the assumption that the physical layer status is ideal,that is to say,there is no transmission impairment of optical signal.And the problem of optical signal impairment is considered in RWA algorithms and the transmission protection is achieved from the angle of the algorithm,thus effectively preventing physical-impai... |
