SDN based network resource selection multi-objective optimization algorithm

针对基于软件定义网络(SDN)的复杂结构中不同资源效用目标共存、资源选择策略相互影响的问题,提出了一种基于SDN的网络资源选择多目标优化算法。该算法综合考虑资源供给方和客户方对资源效用的不同优化目标,构建资源选择多目标优化模型,并采用基于参考矢量的多目标优化算法对模型求解。仿真结果表明,与其他资源优化算法相比,所提算法能够快速收敛得到均匀分布的非劣解集,均衡基于SDN资源接入管理时多方的优化目标。

For the problem of coexistence of different resource utility objectives and mutual influence of resource selection strategies in the complex structure of software-defined network(SDN),an SDN based network resource selection multi-objective optimization algorithm was proposed.The optimization goals of resource providers and clients were taken into account in the algorithm,and a resource selection multi-objective optimization model was constructed.The model was further solved by the reference vector based multi-objective optimization algorithm.Simulation results show that compared with other algorithms,the proposed algorithm could quickly converge to the uniformly distributed non-inferior solution set,and balance the optimization objects of multi-party in SDN based resource access management.
