Service-oriented middleware for peer-to-peer computing

We propose a lightweight service-oriented middleware infrastructure for supporting robust and efficient peer-to-peer (P2P) computing. This middleware uses a community of proxy agents (located in some peers) which cooperate among themselves to offer efficient data sharing and download operations across the P2P network. Our proposed framework provides in-grained Quality of Service (QoS) support for satisfying a wide-range of application-level performance requirements, which is especially critical for emerging real-time P2P services. The proxy agents operate with flexible policies for managing an adaptive distributed storage system. This smart P2P infrastructure support delivers interoperable and reliable services to provide synchronous and asynchronous exchange of data and remote procedure calls (RPC) among concurrent peer-to-peer applications.
