基于粒子群优化的虚拟SDN网络映射算法
Virtual SDN Network Mapping Algorithm Based on Particle Swarm Optimization
摘要
Abstract
Aiming at Software Defined Network(SDN)virtualization environment,an efficient virtual SDN network mapping algorithm is proposed to minimize network mapping overhead.Based on the Particle Swarm Optimization(PSO)algorithm,it redefines the position,velocity and related operations of the particles according to the model of the virtual SDN network,and the mapping problem is solved by iterative optimization of particles.Simulation results indicate that the algorithm improves the resource utilization and the acceptance ratio,and reduces the average controller-to-switch delay.关键词
