A Computational and Engineering View on Open Distributed Real-Time Multimedia Exchange

. An important requirement for distributed multimedia applications is the support of real-time communication and the means to specify real-time aspects. The aim of this paper is to extend RM-ODP and TINA-C computational and engineering views on distributed systems for the specification and support of real-time communication. It is expected that these bodies have a major impact in the area of distributed processing. However, concepts and mechanisms to support real-time communication are not yet fully included or detailed in these standards. In particular this paper addresses Quality of Service (QoS) specifications for continuous dataflows. These QoS specifications are described from the ODP computational and engineering viewpoint and the repercussions of these QoS specifications for functions located in both the computing and telecommunications environment are discussed.
