Abstract :
Multimedia conferencing services have specific performance requirements with respect to the exchange of continuous data like audio and video streams. One of these requirements is the synchronization within and between related streams. Synchronization solutions relevant for conferencing services that operate in a open distributed environment are applied using the TINA-C service life-cycle model as a road map. We refined the phases of the service life-cycle model using the RM-ODP information, computational and engineering languages which are also adopted by TINA-C. Furthermore, a description is given of the implementation in ANSAware of synchronization for a multimedia conferencing service. Finally, the TINA life-cycle model as a development method is discussed
