Semantic integration of web services and peertopeer networks to achieve fault-tolerance

Abstract

One fundamental property that critical Web services need to provide is a high level of availability. Along with the development of Web services, considerable technological advances are being made to use the semantic Web to achieve the automated processing and integration of data and applications. This paper describes the implementation of the Whisper architecture. This architecture semantically integrates Web services with a peer-to-peer infrastructure to increase service availability. Whisper achieves transparent fault-tolerance by automatically forwarding Web service requests to semantically equivalent peers that are dynamically located, selected, and invoked.
