Design and evaluation of an intelligent peer-to-peer distributed file system

In order to support very high capability storage systems, a peer-to-peer distributed file system architecture has been developed along with a prototype implementation. Current systems may have difficulty providing virtual data storage services because they typically only depend on trusted nodes in a local network. To support utilization of nodes beyond a local network, trusted nodes across the Internet need to be used with characteristics along the lines of scalability, availability and becoming profitable if the services are available to paid customers. In this paper we present a novel adaptive rule-based peer-to-peer distributed file system which is able to build a trusted distributed file system environment and enables users to securely store and retrieve their files at either trusted storage nodes or untrusted nodes that are located across the network. We further present some interesting results obtained when a rouge node is presented to the system.
