Title: Positioning of optical networking in the EU FP7 and Horizon 2020 Research Programs
Biography: Andrew Houghton is Deputy Head of the Unit "Future Networks", in the Directorate-General for Information Society and Media of the European Commission, in Brussels, Belgium. He received a B.Sc. degree from the University of Sussex, UK, and a Ph.D. from the University of Nottingham, UK. After five years with BT Research Labs, he joined STC /Northern Telecom Optoelectronics, involved in production of components for optical communications systems. In 1992 he joined the European Commission as a Project Officer, initially in the area of optical networks and subsequently in the areas of "Broadband for All" and "Mobile and Wireless Beyond 3G". He is currently responsible for projects of the ICT FP7 Research Programme, in the "Network of the Future" Objective.
Title: Green, Secure, and Elastic Photonic Network Beyond the Next
Abstract: To cope with everlasting demand for the bandwidth, optical fiber communication technology has been continuously evolving and experienced three generations over three decades; the first ETDM in early '80s, the second EDFA and WDM in late '90, followed by the current digital coherent era. Since early '80s the transmission capacity per fiber has increased 104 times, and the bit rate-distance product per fiber has increased by a factor of one million. Today the transmission capacity per fiber has nearly hit nearly its limit of 100 Tbit/sec.
For better quality of human life, it'd be the time to address the other emerging R&D issues of photonic networks; power consumption, security, and elasticity in bandwidth. 60% growth of ICT power consumption is foreseen in the year of 2020, therefore, the "green" networking technology has to be pushed. IP traffic offload at intermediate nodes has tremendous impact on the reduction of power consumption of Internet, but it'd be not an ultimate solution. Data confidentiality will become more important as the data transfer of sensitive information relys more on the Internet via optical networks. However, the security in physical layer has not been attracting much attention but its importance should be stressed. Because once the security in physical layer breaks down, a quick stopgap measure will not be easily implemented but it takes a painfully long for the remedy. At last but not least, for the better efficiency in bandwidth utilization an elastic bandwidth allocation to the customers in access networks as well as the elastic optical path assignment in WAN and MAN recently attract growing attention.
In this talk, R&D activities of photonic packet router will be introduced. Particularly, a focus is on its application to data centers. Next, secure M-ary optical code division multiplexing (OCDM) will be discussed, which adopts block-cipher to enhance the data confidentiality. Finally, a special class of coherent OFDMA, digitally-supported coherent interleaved FDMA (IFDMA) will be presented for elastic optical access networks.
Biography: Ken-ichi Kitayama received the M.E. and Dr. Eng. degrees from Osaka University, Osaka, Japan, in 1976 and 1981, respectively. In 1976, he joined the NTT Laboratories. In 1995, he joined the NICT, Japan. Since 1999, he has been the Professor of Osaka University, Japan. His research interests are in photonic label switchings, optical signal processings, and next-generation access technology such as OCDMA and OFDMA, and radio-over-fiber (RoF) systems. He has published over 260 papers in refereed journals and holds more than 30 patents. He is the Fellow of the IEEE and the Fellow of the IEICE of Japan.
Title: Research into BT's future optical transport network
Abstract: This talk will review BT's current network architecture and technologies, explaining how we arrived there. It will explain BT's different Lines of Business and how they have to interwork from a regulatory point of view. The impact of this regulation on the network will be discussed. A detailed view of BT's network will be described and the main issues considered in network design. The talk will then focus on the challenges in the future and how BT's research is structured to meet them. It will cover a wide range of topics including the overall BT infrastructure and architecture, technologies used at the optical and higher layers, coherent transmission, dispersion compensation free networks, the potential need for flexgrid, IP over DWDM and alien wave technology. The talk will conclude with a review of some of the more advanced topics under consideration, including virtualised optical networks, bandwidth on demand and multi-domain control planes. The intention in the talk will be to give a general overview of the complete network space and how it impacts on BT, with the objective of informing research within the community at large.
Biography: Andrew Lord is an Optical Specialist at British Telecom where he is responsible for directing research into optical core transport and networks. He received his B.A. Hons degree in Physics from Oxford University in 1985, and joined BT after graduating. He worked on all implementations of DWDM technology since then, including large subsea systems such as TAT14 as well as national and Ministry of Defence DWDM networks. He has helped lead the EU collaborative projects NOBEL and STRONGEST and currently serves on the technical subcommittees of several conferences including OFC and ECOC, where in 2011 he chaired workshops on EON. He is a member of the Institute of Physics.
