A Simulation Framework for Distributed Super-Peer Topology Construction Using Network Coordinates

Scalability constitutes a property of particular interest when investigating peer-to-peer overlay behavior. Recent advances that improve scalability include super-peer infrastructures and network coordinates. To this end, we introduce a lightweight simulation framework that focuses on peer-to-peer topology construction supported by network coordinates and optionally, super-peers. One of the design goals has been a straightforward way to re-use simulation code in practical applications. We illustrate the utility of our simulation framework by means of a comprehensive application case study that compares different network coordinates generation mechanisms in the context of a distributed super-peer topology construction effort.
