Fair Bandwidth and Storage Sharing in Peer-to-Peer Networks

While cooperative p2p applications are designed to share the resources of each computer in an overlay network, users do not necessarily have an incentive to donate resources to the system if they can get the system’s resources for free. We study mechanisms to enforce and encourage sharing for file sharing systems. In this paper, we present two such architectures, designed for systems with different limiting resources, and discuss some problems we faced and our future directions.
