Rashid}, journal={Karbala International Journal of Modern Science مجلة كربلاء العالمية للعلوم الحديثة}, volume={4}, number={3}, pages={313-331}, year={2018}, abstract={The emerged SDN innovation moves the intelligent routing functions out of forwarding devices into the centralized controller toprovide the centralization and flexibility. It detaches the two planes (control and data) via its new architecture and programmingsolutions. Data centers benefit from SDN capabilities in the modern scalable network environments and tends to be managed by acentral entity basing on its global view and intelligent dynamic decisions. Researches showed that elephant flows carried the largestamount of data in such data centers. These Large flows need to be detected and managed to enhance the resources utilization of therecent multi-path topologies.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 ascompared to the GFF and the ECMP routing via examining them on a scalable low cost fat tree data center for various generatedtraffic patterns.
