Sorted-GFF: An efficient large flows placing mechanism in software defined network datacenter

In this work, we developed the requirements for an efficient TE mechanism basing on an intelligent elephant flows management, and proposed the Sorted-GFF flow scheduler. Mininet simulation is used to calibrate the performance of the Sorted-GFF as compared to the GFF and the ECMP routing via examining them on a scalable low cost fat tree data center for various generated traffic patterns.
