Realistic Underlays for Overlay Simulation
Overlay networks have become an enabler for innovation in today's Internet through cost-efficient and flexible deployment of novel services. The self-organization and scalability properties that peer-to-peer-based overlay networks provide have created real-world large-scale systems like Kad, or Amazon's Dynamo. Due to their distributed behavior, developing and evaluating large-scale overlay networks has a much higher complexity in contrast to centralized systems. To cope with this complexity, simulation has proven indispensable for design and evaluation of overlay networks.
