Outline

• Introduction• Demonstration• Hands-on session

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

PrimoGENI is a GENI Aggregate

• Manage the life cycle of network experiments Model Configuration Resource Specification Deployment, Execution Online Control & Monitoring Visualization Data Collection

What’s the Use?

A virtual distributed environment:

A fancy delay node: A traffic generator:

Demonstration

• 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

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

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
