Multimedia Conferencing Services in an Open Distributed Environment
نویسندگان
چکیده
Distributed Processing Environments (DPE) or platforms are regarded as the future telecommunication architecture [1] on which distributed applications such as Multimedia Conferencing (MMC) services will operate. Using the DPE as target telecommunication platform, an important issue for MMC designers is the specification of generic MMC interfaces. This enables MMC users to access, in a distribution transparent way, a wide range of MMC services, that conform to these interface specifications. This paper proposes a classification of MMC services by means of three generic interface templates. These interface templates describe in an implementation independent way the functionality and management related to MMC services. The paper discusses also a possible implementation of these interfaces. Techniques and concepts are used as proposed by RM-ODP [2] and TINA-C [1].
