Performance of SDN-enabled NFP framework in FatTree-based DCN topologies. The performance of the SDN-enabled online NFP framework on K-pod FatTree topologies is shown here. Both core-to-end and end-to-end flows are considered and Path Computation, NFP Computation and Migration Time are plotted for various pod sizes and number of requests. a Comparison of path computation time (in ms). b Comparison of NFP computation time (in ms). c Comparison of migration time (in ms)
