  1. DEMO: Designing and Monitoring OpenFlow Load Balancing Experiments using GIMI Shufeng Huang, DivyashriBhat GENI Project Office, UMass GEC 17

  2. Experiment Design “Design an OpenFlow Controller that does Load Balancing” • Simple topology • Repeatable experiment • Ability to monitor performance of controller

  3. Topology Sender LB Agt R S R L Load Balancer Receiver

  4. Key Words Topology ExoGENI resources OpenFlowSwitces OVS Load Balancer Controller Trema Monitoring GIMI / LabWiki

  5. Design the Experiment • Start several TCP flows from Sender to Receiver • Enable Load Balancing on OpenFlow Switch • Start more TCP flows from Sender to Receiver LB Agt LB R S R L

  6. Design Monitoring • Start several TCP flows from Sender to Receiver • Enable Load Balancing on OpenFlow Switch • Start more TCP flows from Sender to Receiver Monitor LB Agt LB R S R L right left left left right right

  7. Design Orchestration in GIMI # start TCP flows group('Receiver').exec("iperf -s") group('Sender').exec("iperf -c 10.10.10.2 -t 100") group('Sender').exec("iperf -c 10.10.10.2 -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 1..10 group('Sender').exec("iperf -c 10.10.10.2 -t 100") wait 5 end 1.

  8. Design Orchestration in GIMI # start TCP flows group('Receiver').exec("iperf -s") group('Sender').exec("iperf -c 10.10.10.2 -t 100") group('Sender').exec("iperf -c 10.10.10.2 -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 1..10 group('Sender').exec("iperf -c 10.10.10.2 -t 100") wait 5 end 2.

  9. Design Orchestration in GIMI # start TCP flows group('Receiver').exec("iperf -s") group('Sender').exec("iperf -c 10.10.10.2 -t 100") group('Sender').exec("iperf -c 10.10.10.2 -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 1..10 group('Sender').exec("iperf -c 10.10.10.2 -t 100") wait 5 end 3.

  10. Plotting in GIMI defGraph ’Total Traffic' do |g| g.ms('network').select(:oml_ts_server, :tx_bytes, :name) g.caption "Total Traffic" g.type 'line_chart3' g.mapping :x_axis => :oml_ts_server, :y_axis => :tx_bytes, :group_by => :name g.xaxis :legend => 'timestamp', :ticks => {:format => 's'} g.yaxis :legend => 'sent Bytes', :ticks => {:format => 'Byte'} end
