Introducing Heterogeneity in Performance Analysis of P2P Networks for File Distribution

Peer-to-Peer networks have been widely used for file sharing and file distribution. This technical report investigates the performances that can be obtained in a system where two classes of users are present. The study introduces a set of scheme that can be used with different distribution architectures and evaluates the performances that can be obtained with each scheme. Results show that, when we consider heterogeneity, performances may not negatively be affected with respect to the case of single class of users.
