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

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

10. Demonstration

11. 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 Experiment 1: A Simulated Dumbbell Model

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

14. 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
