Abstract. The OSGi Service Platform defines a framework for the deployment of extensible and downloadable Java applications. Many of the application areas for OSGi have significant dependability requirements. This paper presents and evaluates FT-OSGi, a set of extensions to the OSGi Service Platform that allow to replicate OSGi services. FT-OSGi supports replication of OSGi services, including state-transfer among replicas, supports multiple replication strategies, and allows to apply a different replication strategy to each OSGi service.
