Abstract

We present a model of bandwidth allocation in a stylized peer-to-peer ¯le sharing net- work. Given an arbitrary population of peers composed of sharers and freeriders, where all peers interconnect to maximize their allocated bandwidth, we derive the expected band- width obtained by sharers and freeriders. We show that sharers are always better o® than freeriders and that the di®erence decreases as the size of the network grows. This paper con- stitutes a ¯rst step towards providing a general analytical foundation for resource allocation in peer-to-peer networks.
