Abstract

Enabling next generation network to support multimedia streaming services across heterogeneous fixed and mobile networks challenges the developers to define a unified triple play framework solution. The IP multimedia subsystem (IMS) defined by the 3rd generation partnership projects (3GPP and 3GPP2) represents today a basis framework for a service delivery platform (SDP) for providing triple play services. Several approaches have already been introduced struggling with the need for an integrated solution based on the IMS core or the development of a separated subsystem. The Fraunhofer Institute FOKUS has launched the "Open IMS Playground" in July 2004 as part of the German 3G beyond national testbed. The IMS Playground has been extended recently as an open environment gathering all major IMS core components, and triple play toolkit originating from own developments as well as major industry players, which can be used by academic and industrial partners for early prototyping of new triple play services, related components, protocols, and applications. This paper introduces the relevant technologies and provides an overview of the "open NGN/triple play toolkit and testbed @ FOKUS".
