This paper proposes an implementation of the Telecommunications Information Networking Architecture (TINA) connection management system, based on our involvement of The TINA Trial (TTT). The system is used for managing ATM networks, which consist of network elements with SNMP interfaces. It provides setup, configuration, and release of ATM connection with a GUI-based network design tool that generates network resource data used for deploying TINA software components. This paper reports on a method of implementing TINA components over a Distributed Processing Environment (DPE) and an effective way to manage computational objects with multiple interfaces by using the Trading Service.

The OMG have made the trading service one of the basic CORBA services. A specification has been drawn up (OMG RPF5) but seems to have some problems in terms of scalability and complexity. This paper introduces an architecture called Contextual Clustering Using Service Properties (CCUSP) that deals with issues of scalability. It uses a contextual approach to clustering object service offers based on property commonalities. It also handles issues of scalability of trader federation. An ontological approach is to be used, however not covered in this paper. An implementation of the specialisation graph context model is detailed.
