Modeling Multi-Point Transport Protocol in P2P Networks

Congestion control mechanism is investigated under peer to peer application environment. A mathematical model is build to identify the relationships among the key parameters of the M2M transport control, leading to the following results: The downloading rate of a peer will be saturated with the increasing number of peers to download from when no time deadline is required; there exists an optimal number of peers to download from in order to maximize a peer's throughput when timeout mechanism is adopted. We conduct simulation experiments to validate our model.
