Peer-to-Peer I/O (P2PIO) Protocol Specification Version 0.6

Today’s distributed systems require simple and powerful resource dis-covery queries in a dynamic environment consisting of a large number of resources spanning many autonomous administrative domains. The dis-tributed search problem is hard due to the variety of query types, the number of resources and their autonomous, partitioned and dynamic na-ture. We propose a generalized resource discovery framework that is built around an application level messaging protocol called Peer-to-Peer I/O (P2PIO). P2PIO addresses a number of scalability problems in a gen-eral way. It provides flexible and uniform transport-independent resource discovery mechanisms to reduce both the client and network burden in multi-hop P2P systems.
