A consideration on R&D direction for future Internet architecture

The professional Internet system has been operated for more than 20 years, while preserving the continuous introduction of technical innovations. The Internet architecture, of course including the future Internet, must preserve the following five essential features of the Internet architecture. These are (1) autonomous, (2) distributed, (3) disconnected, (4) inter-domain, and (5) global operation. The current Internet system is challenged by the following three aspects; global, ubiquitous and mobility. ISOC, Internet Society (www.isoc.org), has initiated the strategic initiative that is focusing on 'Trust and Identifier'. We must re-design the identifier, directory service, trust model, routing and communication model for the computer system and for the computer networks. For example, Delay Tolerant Networking or Peer-to-Peer system architecture would challenge the introduction of new technological frameworks to the existing Internet. Finally, this paper discusses how to build and how to deploy the future Internet infrastructure. Copyright (C) 2010 John Wiley & Sons, Ltd.
