Interoperability for Peer-to-Peer Networks: Opening P2P to the Rest of the World

Due to the information growth, distributed environments are offered as a feasible and scalable solution where Peer-to-Peer networks have become more relevant. They bring many advantages as high flexibility for peers to join or leave the network dynamically, scalability, autonomy and high resilience against peer failures. However, the use of proprietary interfaces within the network and the requirement that peers must implement them to join makes P2P networks unable to interact with other systems and environments, isolating the network as a whole. In this paper, we report on a solution based on a proxy-based architecture and semantic mappings in order to allow the sharing of content between peers within a P2P network with content from other systems outside the network.
