Fig. 9From: Centralized approaches for virtual network function placement in SDN-enabled networksPerformance of SDN-enabled NFP framework. The performance of the SDN-enabled online NFP framework is shown here. The various delays involved in accomplishing NFP for networks of various sizes are illustrated. a Path computation time (in ms). b NFP computation time (in ms). c Feasibility delay (in ms). d Migration time (in ms)Back to article page
