The authors analyze the performance of a DHT-based P2P overlay network in resource access and overlay maintenance activities. They use a cross-platform implementation of the protocol called P2PP. Mobile systems are the main target platform of the protocol implementation; due to practical reasons, they conduct large-scale evaluations using a server array. The performance metric is the request accomplishment success ratio in the overlay network. The evaluations are conducted in the presence of churn i.e. the peers' continuous activity of joining and leaving the overlay, which is crucial for realistic simulations. The online and offline time-periods of churning peers follow an exponential distribution.
