Abstract
SDL has provided robust and adaptable modelling capabilities through many developments in the world of telecommunications. In recent years, however, that world has undergone deeper and more frequent paradigm shifts than hitherto. This paper briefly summarises the emergence of grid computing, pervasive computing and mobile and ad-hoc communications. It explores developments in modelling, as reflected by the emergence of SDL-2000 as an ITU standard, and the subsequent publication of UML 2.0. It considers the relationship between SDL and UML, including establishment of SDL as a UML profile, work by the MODA-TEL project and the formation of the ETSI specialist task force 250. It concludes with suggestions for specific tasks in the development of the next revision of SDL. This does not represent any new development for SDL, nor does it present any new applications of SDL. Rather it focuses on the forces affecting the evolution of SDL, and the opportunities to be grasped and challenges to be faced.
