Abstract
Virtual network mapping problem is the key problem of virtual network , most of the previous studies focused primarily on link mapping after preselecting the node mapping based on heuristic algorithm .In order to reduce the resource cost and im-prove the acceptance rate of mapping with substrate resource utilization , this paper proposed an optimized two-stage coordinated algorithm by combing the link splitting and migration .Simulation results show that , this algorithm is of better acceptance ratio and benefit-cost ratio.关键词
