Title: Carrier-Grade Networks toward the Future - NGN and Its Issues
Carrier-grade networks for the future are being developed as Next Generation Networks (NGN). The NGN is a converged solution after the legacy telecom networks by enabling QoS management and controls in IP network like in legacy telecom networks and by supporting economical, versatile multi-media applications like those on the Internet. NGN supports voice, Internet services and further services which are being and will be developed in the future with flexible and cost effective manners and with high dependability and high security. It also supports third-party applications through the open interface. NGN also provides more flexible access arrangements such as fixed-mobile convergence (FMC) with generalized mobility, and horizontal and vertical roaming as well as improved security.
The concepts and architecture of NGN are described. The current status of NGN implementation in a commercial offer in Japan is touched upon. Issues for the global evolution of NGN are also described, such as IPv6 related issues, impacts of smartphones, cloud computing, global standards and regulations.
Koichi Asatani received his B.E.E.E., M.E.E.E. and Ph. D degrees from Kyoto University in 1969, 1971 and 1974, respectively. From 1974 to 1997, Dr. Asatani was engaged in R&D on optical fiber communication systems, hi-definition video transmission systems, FTTH, ISDN, B-ISDN, ATM networks, IP networks and their strategic planning in NTT. Currently he is Dean, Department of Computer Science and Communications Engineering, Kogakuin University, and a visiting professor, Graduate School of Global Information and Telecommunication, Waseda University, both in Tokyo, Japan. He is a Fellow of IEEE and a Fellow of IEICE. He was appointed as a distinguished lecturer of IEEE Com Soc for 2007-2009 and 2011-2012.
He is a founder of Communications QoS, Reliability and Performance Modeling series symposium at ICCs and Globecoms. He served as co-chair for this symposium series at ICCs and Globecoms for 2002-2004. He is Ex-Chair and Advisory Board Ex-Chair Emeritus of IEEE Technical Committee on Communication Quality and Reliability (CQR-TC), Feature Editor on Standards (1993-1999), Senior Technical Editor/Technical Editor (1999- 2010) of IEEE Communications Magazine, and Technical Editor on Broadband Technology of IEEE Communications Survey. He served as Executive Chair for ICC2011 in Kyoto, Japan.
From 1988 through 2000, he served as Vice-Chairman of ITU-T SG 13 (formerly CCITT SG XVIII), responsible for digital networks including GII, IP networks and NGN. He is serving as Chair for National Committee on Next Generation Networks in Japan, as Chair, R&D and Standardizations Working Group, Next Generation IP Network Promotion Forum, and as a board member of New Generation Network Promotion Forum.
He has published more than fifty papers, and gave more than seventy talks including keynotes、 invited talks and tutorials at international conferences such as ICCs and Globecoms. He is author or co-author of nineteen books including "Quality and Performance Designs of Telecommunication Networks"(IEICE, 1993, in Japanese), "Introductions to ATM Networks and B-ISDN)" (John Wiley and Sons, 1997), "Multimedia Communications Networks - Technologies and Services" (Artech House, 1998), "Multimedia Communications" (Academic Press, 2001), "Information and Communication Technology and Standards" (Denki Tsushin Shinko Kyokai, in Japanese, 2006), "Introduction to Information Networks-Fundamentals of Telecom & Internet Convergence, QoS, VoIP and NGN-" (Corona-sha Publishing Inc., in Japanese, 2007), and Handbook of Enterprise Integration (CRC Press, 2009). His current interests are Information Networks and Network Architectures including Broadband networking, Internetworking, IP telephony, NGN, Future Networks and their QoS aspects.
