摘要 研究了具有混合传输速率、调制格式和动态色散补偿特性的容量可升级透明光网络中的光路连接分配问题.提出了2种感知损伤的路由波长和补偿量分配算法(IA-RWCA).仿真结果表明,与已有感知损伤的路由和波长分配算法相比,IA-RWCA算法可以显著改善网络性能,降低网络阻塞率. Lightpath connection provisioning problem for capacity upgradeable transparent optical networks with hybrid line rates, modulation formats and dynamic dispersion compensation characteristic are investigated. Two impairment-aware routing, wavelength and compensation assignment algorithms are pro- posed. Simulations show that the proposed algorithms can improve the network performance significantly with much lower blocking probability, compared to the existing impairment-aware routing and wavelength assignment algorithms.
