Ori Gerstel, “Multi-layer interworking and SDN: a perfect match”
Ori Gerstel is the founder of SDN Solutions – a consulting company specializing in of SDN and multi-layer networking. Until the end of 2013, Ori was a Principal Engineer at Cisco, where he was responsible for identifying opportunities for integration of routers and transport technologies. Before joining Cisco in 2002, Ori held senior architecture positions at Tellabs and Nortel, where he architected the first mesh optical network and the first fully switched optical network respectively. He started his work in optical networking at IBM, where the first commercial DWDM system was developed. For his contribution, he was awarded the grade of IEEE Fellow (2008) and OSA Fellow (2013).
Ori published over 90 papers in the main international conferences and journals in the field, as well as several book chapters. He holds over 35 granted patents on optical networks, and a similar number of pending patents. He served as conference committee member and co-chair of several communication conferences and has been regularly invited to teach short courses and attend panels. He also serves as editor-in-chief for the primary journal for optical networking (JOCN) and as a steering committee member for the OFC/NFOEC conference. Ori holds a Ph.D. degree from the Technion.
Abstract:
Most WAN networks are managed inefficiently today due to the lack of awareness and automation across layers. We believe that this inefficiency is unsustainable due to pressures on the SP business model, and due to the insufficient improvement of the cost and spectral efficiency of DWDM technology, compared to the ever increasing desire for more capacity.
Multi-layer interworking promises significant improvement in the efficiency of the network and its ability to adapt to changing traffic conditions. It also enables higher availability – especially in the face of significant failures and disasters. It turns out that much of the required coordination cannot be achieved via distributed control, and therefore SDN is a critical ingredient of the solution. However, an evolutionary approach is needed to achieve wide-spread deployment, and taking an extreme fully-centralized approach is also not the right solution. To this end, we will explore realistic hybrid approaches.
Vincent W.S. Chan, “Dynamic, Fast and Agile On-Demand Optical Network Architecture”
Vincent W. S. Chan, the Joan and Irwin Jacobs Professor of EECS, MIT, received his BS(71), MS(71), EE(72), and Ph.D.(74) degrees in EE all from MIT. From 1974 to 1977, he was an assistant professor, EE, at Cornell University. He joined MIT Lincoln Laboratory in 1977 and had been Division Head of the Communications and Information Technology Division until becoming the Director of the Laboratory for Information and Decision Systems (1999–2007). He is currently a member of the Claude E. Shannon Communication and Network Group at the Research Laboratory of Electronics of MIT.
In July 1983, he initiated the Laser Intersatellite Transmission Experiment Program and in 1997, the follow-on GeoLITE Program. In 1989, he led the All-Optical-Network Consortium formed among MIT, AT&T and the Digital Equipment Corporation. He also served as PI of the Next Generation Internet Consortium, ONRAMP formed among AT&T, Cabletron, MIT, Nortel and JDS. He has founded in 2009 and served as the Editor-in-Chief of the Journal of Optical Communications and Networking until 2012. He has served in many government advisory boards and is currently a Member of the Corporation of Draper Laboratory and on the Board of Governors of the IEEE Communication Society as VP of Publications. He is an elected member of Eta-Kappa-Nu, Tau-Beta-Pi and Sigma-Xi, the Fellow of the IEEE and the Optical Society of America.
Abstract:
Present-day networks are challenged by dramatic increases in data rate demand of emerging applications. With the advancement of high speed fiber communications with per wavelength transfer rate of 100Gbps or more and free space optical links for close-in data/computing center interconnects, unscheduled high speed data transfer of ’elephant’ (large volume) transactions are a reality. To make full use of the technology of optics and the very high data transfer rates, new network architectures from the physical to the transport layer are needed. This talk will address new network architectures, free of constraints of previous architectures and protocols, that will make ’elephant’ transactions much more efficient with much less network delays. Substantial performance gains can be expected for these new networks not just because the physical layer is faster but the upper layer protocols are also much improved in performance due to radical changes in architectures.
Ari Sorsaniemi, “Optical Communications in the context of H2020”
Ari Sorsaniemi joined the European Commission and its Radio Spectrum Policy unit in DG INFSO in 2004. His responsibilities as Policy Developer included spectrum usage aspects in the context of transport and satellite sectors, as well as within smart energy grids and smart metering systems. He then moved to a unit called Smart Cities and Sustainability, dealing with policy issues and FP7 project coordination related tasks linked to energy efficiency and smart grids. Now he is working on projects and policy issues within the areas of Internet of Things, Optical Communications (e.g. monitoring FP7 optical projects DISCUS, IDEALIST, LIGHTNESS, COCONUT and STRAUSS) and 5G PPP, including shared use of spectrum, in the Network Technologies unit of DG CONNECT (Communications Networks, Content and Technology).
Ari started his professional career in process automation, but moved into telecommunications sector in 1990, working in an R&D project environment at the time when the first 2G (GSM) mobile networks were being developed. He changed into sales and marketing in 1993, working in Finland, Australia and Mexico in various marketing management functions. After having moved to Belgium in 1998 he continued working in the area of system marketing, after which he was responsible for the sales and marketing support activities in Belgium and later he dealt inter alia with business operations and strategic marketing related matters.
Ari received his master’s degree in electrical engineering at Tampere University of Technology, Finland.
Abstract:
The main objectives of this presentation are to emphasise the importance of Optical communications, which is also linked to some of the other key areas within the H2020 programme, for example to Components and Systems, as well as to Software Defined Networking (Advanced 5G Network Infrastructure) and to provide an update on the H2020 and its first Call.
