摘要：

In this paper, the virtual network embedding reconfiguration (VNER) problem on elastic optical networks (EONs) with time-varying traffic was studied. Two reconfiguration methods: Most extra Resource First (MRF) and Less Extra Resource First (LERF) and three link expansion methods Same Path (SP), Different Path (DP) and Redeploy method (Rm) were proposed to solve the VNE reconfiguration. We show the effectiveness of the proposed methods through extensive simulations. The results show that the blocking rate of the MRF_Rm method is 2% to 7% lower than the other reconfiguration algorithms. The LRF scheme is better than the MRF scheme.
