1 Sponsored by the National Science Foundation DEMO: Designing and Monitoring OpenFlow Load Balancing Experiments using GIMI Shufeng Huang, Divyashri Bhat GENI Project Office, UMass GEC 17

2 Sponsored by the National Science Foundation 2 GEC17 Experiment Design “Design an OpenFlow Controller that does Load Balancing” Simple topology Repeatable experiment Ability to monitor performance of controller

3 Sponsored by the National Science Foundation 3 GEC17 Topology S LB L R Agt R Sender Receiver Load Balancer

4 Sponsored by the National Science Foundation 4 GEC17 Key Words Topology ExoGENI resources Load Balancer Controller Trema Monitoring GIMI / LabWiki OpenFlow Switces OVS

5 Sponsored by the National Science Foundation 5 GEC17 Design the Experiment 1.Start several TCP flows from Sender to Receiver 2.Enable Load Balancing on OpenFlow Switch 3.Start more TCP flows from Sender to Receiver S LB L R Agt R LB

6 Sponsored by the National Science Foundation 6 GEC17 Design Monitoring S LB L R Agt R LB 1.Start several TCP flows from Sender to Receiver 2.Enable Load Balancing on OpenFlow Switch 3.Start more TCP flows from Sender to Receiver left right left

7 Sponsored by the National Science Foundation 7 GEC17 Design Orchestration in GIMI # start TCP flows group('Receiver').exec("iperf -s") group('Sender').exec("iperf -c t 100") wait 20 #start load balancer Group('Switch').exec("/opt/trema-trema- f995284/trema run /root/load-balancer.rb") #start a couple of new TCP flows for i in group('Sender').exec("iperf -c t 100") wait 5 end

8 Sponsored by the National Science Foundation 8 GEC17 Design Orchestration in GIMI # start TCP flows group('Receiver').exec("iperf -s") group('Sender').exec("iperf -c t 100") wait 20 #start load balancer Group('Switch').exec("/opt/trema-trema- f995284/trema run /root/load-balancer.rb") #start a couple of new TCP flows for i in group('Sender').exec("iperf -c t 100") wait 5 end

9 Sponsored by the National Science Foundation 9 GEC17 Design Orchestration in GIMI # start TCP flows group('Receiver').exec("iperf -s") group('Sender').exec("iperf -c t 100") wait 20 #start load balancer Group('Switch').exec("/opt/trema-trema- f995284/trema run /root/load-balancer.rb") #start a couple of new TCP flows for i in group('Sender').exec("iperf -c t 100") wait 5 end
