1. PrimoGENI – Developing GENI Aggregate for Real-Time Large- Scale Network Simulation Jason Liu, Julio Ibarra, Heidi Alvarez Florida International University

2. Background Network Experimentation: –analytical models, simulation, emulation, physical testbed Simulation vs. Emulation Real-time network simulation –Run simulation in real-time –Interact/integrate with real applications

3. PRIME Parallel real-time network modeling environment LARGE network scenarios Our solutions: –Run fast: parallel and distributed simulation –Run cheap: hybrid traffic models –Scalable emulation infrastructure: VPN & virtual machines

4. PrimoGENI-us Scope: Prototype development –Aggregate manager –Experiment workflow tools Infrastructure development –Region backbone: FLR, NLR, Internet2 –International connections: Kyatera, GIGA in Brazil

5. Issues PrimoGENI as an aggregate Export “sliver” as a virtual network with simulated and/or emulated network entities Define “resources” as simulated and/or emulated network entities  resource discovery/specification Tricky for RSpec: need to specify resource types only (and associated supporting platform) Ticketing: network topology, traffic, routing, … Tools for configuring, building, connecting, servicing (data collection and visualization), steering, and tearing down “slivers” Resource sharing issues Model Opt-In
