Pan European IN Reference Architecture

This paper is designed to identify the issues concerned with pan European service provision, though many of the ideas presented are equally applicable to the global services market. To form a foundation for the discussion, the status of current international services is reviewed using a few well known examples. Having established the current service environment, the drivers behind the move from national to pan European service provision are presented. The rest of the paper is then dedicated to the study being carried out by Eurescom into enabling pan European IN services. Firstly the choice of a set of candidate services for initial investigation is explained. Based upon the requirements for these services, the various implementation issues are discussed. Having highlighted the issues, a series of implementation options are presented. Finally the presentation concludes by highlighting the current findings of the Eurescom project. It is then intented that a question/discussion forum be opened in which the options for pan European and international services can be debated.
