Joint multi-dimensional resource allocation algorithm for a TWDM/OFDM-PON-based software-defined elastic optical access network

Abstract With the rapid growth of high-bandwidth services such as 5G, access networks only rely on physical layer technology to build a large-scale rigid pipeline, but cannot meet the need for the intelligent, flexible, and open networks of future business. Therefore, we herein propose a fairness-aware joint multi-dimensional resource allocation algorithm. It is based on software-defined elastic optical access network architecture and is intended to improve network throughput and the quality of service users experience. The simulation results show that the network throughput and user satisfaction rate of the proposed algorithm increases by about 30% during peak traffic periods compared with fixed allocation. The proposed algorithm can ensure that all users utilize the system bandwidth fairly.
