Abstract

In spite of the great number of works on fault tolerance in web services, none of them, to the best knowledge of the authors, establishes a client-transparent failover mechanism without proxies. The main contribution of this paper is an extension to the WS-Addressing standard which allows the specification of replicas of a service and defines the way endpoints shall interact. Additionally, evaluation of a prototype, based on the Axis2 web services framework, that implements a subset of the extension is also given.
