Specification of Audio/Video Exchange Based on the Reference Model of ODP

摘要

The Reference Model of Open Distributed Processing (RM-ODP) is an emergingstandard. It provides a framework of abstractions based on viewpoints, and it defines five viewpoint languages to model open distributed systems. This paper uses the viewpoint languages to specify multiparty audio/video exchange in distributed systems. To the designers of distributed systems, it shows how the concepts and rules of RM-ODP can be applied. The ODP 'binding object' is an important concept to model continuous data flows in distributed systems. We take this concept as a basis for multiparty audio and video flow exchanges, and we provide five ODP viewpoint specifications, each emphasizing a particular concern. To ensure overall correctness, special attention is paid to the mapping between the ODP viewpoint specifications.
