  1. PrimoGENI Tutorial Jason Liu, Miguel Erazo, Nathanael Van Vorst Florida International University GEC12, November 2, 2011, Kansas City, MO

  2. Outline • Introduction • Demonstration • Hands-on session

  3. PrimoGENI enables hybrid network experiments • Including simulated, emulated, and physical components • Simulation • Experimentation at scale • Modeling abstractions • Flexibility • Emulation • Real applications • Resource multiplexing • Physical Networks • Real traffic

  4. PrimoGENI is a GENI Aggregate

  5. PrimoGENI has an IDE • Manage the life cycle of network experiments • Model Configuration • Resource Specification • Deployment, Execution • Online Control & Monitoring • Visualization • Data Collection

  6. Network Visualization Interactive Console Execution Model Java Model Model Compilation In-Memory Model (JAVA) Python Model Model Partitioning XML Model DBMS

  8. What’s the Use? A traffic generator: A fancy delay node: A virtual distributed environment:

  9. Demonstration

  10. Experiment 1: A Simulated Dumbbell Model • Develop network model in Java • Create experiment • Inspect and change network configurations in the attribute tree and the python console • Launch experiment on local host • Visualize traffic flowing on the network

  11. Experiment 2: An Emulated Campus Network Model • Generate/compose large networks • Specify emulated hosts/routers • Set up execution environment (using a preallocatedProtoGENI slice) • Launch experiment on the ProtoGENI slice • Create emulated traffic (traceroute, iperf) • Monitor real-time traffic using LiveGraph

  12. Experiment 3: HTTP Client Cloud • Set up and run Apache server on a real node • Create a campus model for simulated clients • Specify stochastic HTTP requests (from simulated client to real server) • Observe data transfer using tcpdump and from server log
