  1. M. Bhusal, Effect of Service Time Distribution on the Performance of P2P File Sharing, Helsinki University of Technology, 2008, Special assignment (pdf)(bib)
    Abstract: Few studies have been done on the performance analysis of peer to peer (P2P) file sharing systems. They are limited to modelling the systems where the service time is exponentially distributed. In this special assignment, the effect of other service time distributions such as Erlang-2 and hyper-exponential-2 distribution in addition to the exponential distribution on the performance P2P system is studied. The different service time distributions model the kind of service the peers experience in a particular P2P system. A tandem queue consisting of two queues is considered to model the system under study. Although most of the P2P applications employ multiple chunks in file sharing, one chunk model is considered here for its simplicity. This model is first analyzed using deterministic fluid model. A more detailed analysis is done using the Markov chain analysis. The study also takes into account the stability of the system in relation to the arrival and departure rates of the peers. The simulations are performed finally which verify the analytical results.
