Abstract:
Service oriented environments and peer-to-peer networks are on the forefront of research. This paper addresses the issues that arise when attempting to integrate these technologies, while at the same time makes explicit the benefits that can be gained from this integration. We propose the creation of a proxy for web services that allows the deployment of multiple instances of the same traditional web service in a peer-to-peer network. This proxy handles service discovery in the peer-to-peer network and can be used by existing clients with no modifications, thus offering a transparent way access to resource replication and decentralisation benefits that are traditionally associated with peer-to-peer networks. We then proceed to adapt a business process execution engine to be peer-to-peer aware, allowing the implementation of process partition and delegation techniques that can result in reductions in the network traffic required to execute a business process, as well as in a more efficient distribution of the service load through available peers.
