Research Of Impairment Aware Network Resource Optimization Algorithm

With rapid development of optical network technology,explosive growth of network services and user's high network performance demands,all optical networks emerge at the right moment.All-optical network can meet the requirements of large bandwidth,high quality,low energy consumption,low latency and other transmission requirements,it is the development trend of transmission networks in the future.In the all-optical network,with the growth of network size and increasing of transmission requirements,the impact of the physical impairment is becoming larger that cannot be ignored.This paper selected some impairments to establish a normalized impairment model to do calculation through the analysis of the physical impairment.And proposed a new algorithm based on impairment perception by combine impairment model with routing structure and network resource allocation algorithm.The feasibility and practicability of the algorithm are verified through simulation.This paper studies the routing and resource allocation algorithms in all-optical networks,which can improve the network performance of all-optical networks to meet the needs of future development.
