研究了虚拟网络映射动态过程,发现虚拟网络映射代价收益动态倒置现象,提出虚拟网络多路径链路映射的最小费用流模型及算法,适用于在大规模底层网络上在线创建虚拟网络。仿真结果表明本文所提算法能够提高虚拟网络接收率及系统收益,并显著降低了算法时间复杂度,保证在线虚拟网络映射实时性,同时验证了虚拟网络映射代价收益动态倒置现象。
The dynamic process of network virtualization was studied
and the inversion phenomenon that the revenue did not rely on embedding cost was discovered.Then minimum cost flow model and algorithms of virtual network embedding which fit for creating virtual network online on the large-scale substrate network were proposed.Simulation results reveal that the proposed algorithms can improve virtual network acceptance ratio and system revenue
and significantly reduce the time complexity of multi-path virtual link embedding algorithm which ensures real-time performance of online virtual network embedding.The inversion phenomenon also occurs in the simulation.
