Abstract
The Telecommunications Information Networking Architecture (TINA) is a software architecture that is currently under development by the TINA Consortium (TINA-C). Th: architecture will provide an environment for the construction, operation and management of broad range of services, ranging from standard to new sophisticated types, like multimedia. TINA adopts the Open Distributed Processing (ODP) approach that is an emerging ISO/ITU-T standard. ODP provides a framework of abstractions based on multiple viewpoints to specify open distributed applications and systems. A viewpoint is a part of the specification of complete system determined by a particular interest. TINA principles and concepts are specified using enterprise, information, computational and engineering ODP viewpoints. Th: paper considers the TINA computational and engineering viewpoints to specify a vide broadcast service. In the TINA Computational Model, a Communication Session is specified and represented as a communication path (called binding object) between video server and the clients. In the TINA Engineering Model, the infrastructure that provides this communication revelead. Finaly, TINA computational and the engineering specifications are mapped onto an ATM based technology. ATM offers important characteristics required by multimedia applications such as variable bit rate, QoS guarantees, effectiveness of the transport and adaptation functions for the transport of all types of services in a single network. In this technology mapping, ATM call and connection control operations are considered and related to TINA architecture.
