Impairment-aware dynamic RWA algorithm in multi-granularity WDM optical networks

摘要：

In practical multi-granularity WDM optical networks, optical signals will be degraded due to impairments mainly introduced by a number of multi-granularity optical cross-connects (MG-OXC) and fiber links. Even worse, transmission impairments will make the bit-error rate to be unacceptable. We investigate the impact of transmission impairments on optical signal quality in multi-granularity WDM optical networks. A novel dynamic impairment-aware RWA algorithm is proposed based on the presented transmission impairments model. We also evaluate the proposed algorithm in the serial cascaded MG-OXCs network and the interconnecting MG-OXCs network by simulations.
