Implementation of TINA-based high-quality multimedia networks

Telecommunications Information Networking Architecture (TINA) is aiming at reusability and interoperability of software by use of location/fault transparency of objects based on distributed processing and object orientation technologies. Currently many attempts to realize TINA commercial systems are ongoing all over the world. As the first step of those attempts, the TINA Trial (TIT) is scheduled to be realized in 1998. To achieve the quality to be used for the commercial systems, quality study not only of software but also of hardware platforms becomes key. This paper intends to clarify the requirements of TINA-based high-quality multimedia networks and possible solutions by considering the TIT system which the authors are developing. The requirements from the perspective of quality are effective usage of system processing capability by effective multiprocessing without any processing overhead and improvement of system stability by fault management achieving autonomous system reconfiguration. This paper shows the desirability of applying stream-oriented data-driven processor to the TINA system so as to satisfy these requirements. (C) 1998 Scripta Technica.
