Backward-Compatible Cooperation of Heterogeneous P2P Systems

Abstract : Peer-to-peer (P2P) systems are used by millions of users everyday. In many scenarios, it is desirable for the users from different P2P systems to communicate and exchange content resources with each other. This requires co-operation between the P2P systems, which is often difficult or impossible, due to the two following reasons. First, we have the lack of a dedicated routing infrastructure throughout these systems, caused by the incompatibilities in overlay networks on top of which they are built. Second, there are incompatibilities in the application protocols of these systems. In this paper, we introduce a new model for backward-compatible co-operation between heterogeneous P2P systems. The routing across systems is enabled by introducing a super-overlay formed by a small subset of peers from every system, which run an overlay protocol called OGP (Overlay Gateway Protocol). The incompatibilities in the application protocols of P2P systems are solved by a co-operation application, running on top of OGP, bridging these systems at interface level. As a real application, we present a protocol named Inter-network File-sharing Protocol (IFP), running on top of OGP, aimed at co-operation of P2P file-sharing networks. The experimental results performed on the large-scale Grid5000 platform show our model to be efficient and scalable.
