Muxi Liu, Feng Yan, Weiwei Xia, Jinhua Hu, Lianfeng Shen · 2024
In this paper, we design a three-layer architecture under software-defined network (SDN) control in order to solve the problem of communication between heterogeneous networks. In this architecture, we design an optimization problem that varies from different requirements of quality of service (QoS). Afterward, an approach for calculating weights is used in the optimizing objective to find a balance of multiple parameters. Based on solving optimization problems, we propose a mission-classified weighting optimization routing algorithm (MCWO-RA), which makes pertinent improvements in network performance. Simulation results show that MCWO-RA can bring optimization in delay, rate, packet loss rate of mission and meet the requirement of heterogeneous networks.
