The Future Carrier Network: Its Vision and Architecture

Abstract

We have been considering the architecture of the future carrier network which will be the successor to Next Generation Network (NGN). Our assessments have clarified the key problems that will arise in the era when NGN has matured. Based on our studies, we define the vision and the architecture that can solve these problems. This paper provides a snapshot of our work in order to contribute to research on the New Generation Network and beyond.
