Abstract

Existing telecommunications networks and classical roles of operators are subject to fundamental change. Core network technologies have been redefined under the label of Next Generation Networks (NGN) and the transition from existing legacy infrastructures towards an all-IP based NGN is ongoing. Following this paradigm shift within telecommunications, new approaches in services and service composition are currently explored for converging network domains to support legacy circuit-switched networks, NGNs, and integration with the World Wide Web (WWW). Furthermore, emerging initiatives as the Japanese Architecture Design Project for New Generation Network (AKARI), U.S.-based Global Environment for Network Innovations (GENI), Germany Laboratories (G-Lab), and the European Future Internet Research & Experimentation (FIRE) envision a Future Internet allowing automatic cross-layer network adaptation on a service-specific basis. In this report, we describe our setup of a service-oriented research facility for services on top of converging networks as a starting point for service composition in inter-domain, federated testbed environments to allow cross layer service and network composition.
