Event notification is essential in network management. Many components in a distributed NMS need an event notification mechanism, and so ail event notification framework is expected to facilitate the development of the components. CORBA is a promising platform to build such a framework, hut its performance is not sufficient for monitoring large-scale networks. This paper proposes an event notification framework that has high performance and customizability. The framework is based on Java and CORBA, and has customization points at which event handling capabilities call be added. Java gives the framework flexibility in the sense that event handling capabilities call be added and replaced dynamically by using downloadable Java programs. High throughput of more than 1000 events per second has been achieved by event hatching.

Architectural frameworks have shown to increase the design reusability in large-scale object-oriented systems. Drawing on experience in complex software systems development in telecommunication domain, we present concepts and techniques for domain partitioning and architectural framework modeling and layering. In particular, we discuss how a component-based approach, architectural modeling styles, and the systematic usage of architectual and design patterns provide a common framework for product-line development. Two application frameworks based on this model are presented as case studies.

This paper presents a new framework for the conceptual analysis of model management. The framework is object-oriented in the sense that it emphasizes the concepts of data abstraction, information hiding and inheritance. It consists of two parts, namely a conceptual structure for the specification of mathematical decision models and a set of high-level manipulation operators over the conceptual structure. The proposed framework helps to reduce redundancy and avoid inconsistency in the conceptual analysis of model management;as well, it provides a blueprint for building an object-oriented model management system.

This paper presents two algorithms: for a minimal cost shared multicast tree construction (MCTC), and for a scalable multicast session call establishment, called multicast tree development (MCTD). Both algorithms are of original design based on a network simplex presentation, providing a new effective approach to the MCTC, and an object-oriented modelling framework providing the highest scalability for sparse groups with high dynamics of membership, different quality of service requirements and multiple senders. A new approach is proposed for the MCT construction-bidirectional growing of the MCT without pruning;instead the MCTD makes use of extra branches to improve reliability and advertise new receivers.

A description is given of Intermedia, a tool designed to support both teaching and research in a university environment. This multiapplication hypermedia system provides linking capabilities integrated into a desktop user environment. Hypermedia is simply an extension of hypertext that incorporates other media in addition to text. To promote consistency, the applications were built with an object-oriented framework. A sample Intermedia session is presented.
