Provisioning of multimedia services over open NGN testbed

Provisioning of multimedia services over next generation network and across heterogeneous fixed and mobile networks challenges the developers to define a unified triple play framework solution. However the IP Multimedia Subsystem (IMS) defined by the 3rd Generation Partnership Projects (3GPP and 3GPP2) represents today a basis framework that enables the vision of providing triple play services with quality of service and mobility support across heterogeneous networks. The Fraunhofer Institute FOKUS has recently launched the FOKUS Media Interoperability Lab (MIL) that is based on the "Open IMS Playground" testbed. MIL is 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 testbed architecture and the relevant multimedia services at FOKUS. The validation of this architecture is demonstrated with an implementation in the testbed.
