Assurance Diversity Network Platform for NWGN - From New-Generation Network Vision to Multiple Customized Networks

This paper describes an assurance diversity network platform for the New-generation Network (NWGN)/Future Internet. The primary focus is on the vision and five concrete network targets to realize the NWGN, which should ultimately contribute to global society over several decades. In the latter half of the paper, we propose a diversity network platform (DNP) concept for effectively accommodating various networks concurrently. In the DNP, physical resources such as network bandwidth, computation, and storage are managed as a logically integrated resource. Optical/electronic, path/packet, and wired/wireless networks are also managed as a unified network. Apart from this, a new network can be created by installing new functions since the unified network is equipped not only with network resources but also computation and storage resources. Later in the paper we describe technological challenges for the assurance DNP that is the DNP with error-tolerant and reliable features.
