This paper describes the effectiveness of stream-oriented data-driven scheme for achieving autonomous fault management of hyper-distributed systems such as networks based on the Telecommunications Information Networking Architecture (TINA). TINA, whose specifications are in the finalizing phase within TINA-Consortium, is aiming at achieving interoperability and reusability of telecom applications software and independent of underlying technologies. However, to actually implement TINA network, it is essential to consider the technology constraints. Especially autonomous fault management at run-time is crucial for distributed network environment because centralized control using global information is very difficult. So far many works have been done on so-called off-line management but runtime management of service failure seems immature. This paper proposes introduction of stream-oriented data-driven processors to the autonomous fault management at runtime in TINA based distributed network environment. It examines the features of distributed network applications and technology requirements to achieve fault management of those distributed applications such as effective multi-processing of surveillance, testing, reconfiguration in addition to ordinary processing. It shows basic features of stream-oriented data-driven processors which performs effective multi-processing without any overhead, overload tolerance, and passive nature giving less side-effects to the environment based on dynamic data-driven scheme which is realized as autonomous elastic pipelines on VLSIs. Effectiveness of the features is demonstrated through some preliminary experiments. The feature is suitable for runtime management. Then, it is proposed to apply the processor to the fault management of TINA environment and is shown that the stream-oriented data-driven processor can achieve effective fault management capability such as surveillance, fault detection, and isolation without any overhead.

We study a networking architecture model that is built on a distributed processing environment (DPE) for multimedia services suitable for high speed transport networks such as ATM networks. In this architecture, the applications are deployed as units of software building blocks. Each building block provides a layered view for the effective management and control of the multimedia network resources and services according to the concept of telecommunications management network (TMN) and telecommunications information networking architecture (TINA). For the purpose of flexible service provision to users and effective service introduction by service providers, this architecture proposes the adoption of ad hoc service building blocks such as a video on demand building block and a CSCW building block that have interactions with a general purpose building block. This paper also proposes a naming structure for the management of user profiles and session profiles using a directory service system, and an effective control model for multimedia logical device objects using a stream process approach. The proposed model is implemented on a DPE platform that provides various transparencies, ANSAware.

This paper proposes a novel networking architecture on a distributed processing environment (DPE) for various multimedia services suitable to high-speed networks and for the flexible and rapid introduction services in an open networking environment. Furthermore, the proposed architecture is realized as a testbed. This architecture has the following features: (1) the use of DPE for the rapid introduction of service to users and for the flexible management of multimedia network resources;(2) the definition of the service session and connection management for efficient managing functions of the session and connection;and (3) the introduction of any special service with the use of an Ad Hoc service manager. The interfaces scheme between a service session manager that is implemented on a DPE platform and an Ad Hoc service manager is an important aspect in an open networking environment. A CSCW application is given as an example of an Ad Hoc service manager.

We are developing GENESIS, a new seamless total environment for designing, developing, installing, and operating various types of telecommunication networks as extremely large distributedprocessing applications in the future network integrated by ATM. Similar uniform architectures for quick introduction and easy management of service or operation applications have been proposed, such as by TINA, but there has been insufficient study on how to operate and configure those applications. This paper discusses the implementation model and execution environment in GENESIS from the viewpoint of flexible operation according to network conditions. The implementation model can describe detailed configurations under various conditions on design or operation, independently of the execution environment. To achieve the goals of GENESIS, our execution environment provides message handling functions and a transparent interface for controlling network resources independently of the configuration, and dynamic reconfiguration functions that are independent of the execution. This paper also reports the prototype system GENESIS-1 The GENESIS-1 message handling mechanism and the effect of the reconfiguration functions are described.
