Colloquium Topic: A Telecommunications Architecture for the 21st Century

Since the latter half of the nineteenth century, telecommunications services and infrastructures have been driven by voice applications implemented over circuit based technologies. The revolution in data communications, along with equivalent revolutions in technology, have changed not only the forces driving the industry, but also the infrastructure solutions being implemented to meet these customer needs. Furthermore, we have witnessed an increased importance in information management as an integral part of these solutions. This talk will discuss architectural work done to address these issues, and use this work as part of a more general discussion on the architecture development process for complex systems and the role of information management in systems solutions.
