  1. Leveraging OpenFlowfor Resource Placement of Virtual Desktops Project Team:Prasad Calyam, Ph.D. pcalyam@osc.edu, SudharsanRajagopalan, ArunSelvadhurai, Alex Berryman, Saravanan Mohan, Prof. Rajiv Ramnath Research Sponsors: NSF (CNS-1050225, CNS-1205658), VMware GEC15 Plenary Session Talk October 2012

  2. Topics of Discussion • VDCloud-GENI Experiment Context • ‘VDC-Sim’: Virtual Desktop Cloud Simulator • Research use cases • Education use cases • VDCloud Experiment Demonstration • GENI Slice setup • OpenFlow integration • VDC-Sim results ‘with’ and ‘without’ load balancing

  3. Virtual Desktop Clouds (DaaS) “Brain of the Cloud”

  4. Roller Coaster Track Design • Understand energy transfer (potential to kinetic) • Build cool coasters, study tsunamis – similar science • Optimal design: hills, bigger loops, more cars, safe stop Credit: National Geographic, The Jason Project

  5. Roller Coaster Test

  6. Roller Coaster Performance Resource Allocation Net-utility User Experience

  7. VMLab-GENI Experiment Context “VDC-Sim” Provisioning and Placement • VDC-Sim→ GENI • Design & Development → • Validation and design tuning • Large-scale simulations → • Cloud deployment experiments GENI Slice Testbed

  8. VDC Research “Big Picture” 4. Local/Global Distributed Optimization for VD Placement 1. VDBench: Thin-client Performance Benchmarking 2. Deriving Application Behavior Profiles 3. Utility-directed Resource Allocation Model (U-RAM) for VD Provisioning

  9. VDC-Sim Features Resource allocation of thin-clients to data centers ‘Run Simulation’ (Offline) ‘Run Experiment’ (In GENI) Net-utility per experiment run

  10. VDC-SimDemo-1 Resource allocation of thin-clients to data centers VD Requests Load = 100; No Fault Occurrences Net-utility = 21.64

  11. VDC-SimDemo-2 Resource allocation of thin-clients to data centers VD Requests Load = 100; Fault Occurrence Levels = 50 Net-utility = 20.44

  12. Use Cases • Research • Plug-in new provisioning and placement schemes • Study cloud dynamics to see how they affect net-utility • Education • Explore server-side adaptation • E.g., write a macro script to reduce user interaction round-trips for control actions during network health bottlenecks • Explore client-side adaptation • E.g., select thin-client encodings that delivers best QoE for different user groups – knowledge worker vs. designer/artist

  13. Marker Packet Header Format

  14. Flow Setup Sequence Diagram Virtual Desktop OpenFlow Switch OpenFlow Controller Smart Thin-client Join OpenFlow network 1 Install flow rules for marker packets 2 Send marker packet to request virtual desktop 3 • Recognize and punt the marker packet 4 • Parse marker packet and install client/server flows 5 • Access virtual • desktop applications 6

  15. VDCloudExperiment w/o Load-Balancing

  16. VDCloudExperiment w/ Load-Balancing

  17. Demonstration • Route setup • Cross-traffic Impact • Load-balancing Improvement • Step-2 • Step-1 • Step-3 BandwidthConsumed (Mbytes/s) Video runs smooth, GUI applications are responsive Video freezes, disconnects, GUI applications are not responsive Video runs smooth, GUI applications are responsive
