The IP Multimedia Subsystem (IMS) is an architectural framework for delivering IP multimedia services. The appearance of Software Defined Networks (SDNs) concept in the IMS fabric can unleash the potential of the IMS technology which enables access agnostic services including applications like video-conferencing, multi-player gaming, white boarding all using an all-IP backbone. SDN requires some method for the control plane to communicate with the data plane. One such mechanism is OpenFlow which is a standard interface for controlling computer networking switches. This work presents our experience and implementation efforts in integrating OpenFlow mechanisms within IMS. Since this work also is done within the Future Internet Research and Experimentation domain, we also describe how we enabled our infrastructures with experimentation mechanisms.

This paper describes a component-based software architecture and design methodology, which will enable efficient engineering, deployment, and run-time management of reconfigurable ambient intelligent services. A specific application of a media player is taken as an example to show the development of software bundles according to the proposed methodology. Furthermore, a software tool has been developed to facilitate composition and graphical representation of component based services. The tool will provide a model of a generic reusable component, and the user of the tool will be able to instantiate reusable components using this model implementation. The work has been carried out within the European project COMANCHE 1 that will utilize component models to support Software Configuration Management.
