Directions and Challenges of Software-Defined Networking (SDN)

Software-defined networking (SDN), by decoupling control from forwarding, provides a great framework to unleash the potentials of communication networks. SDN is a programmatic way to more effectively integrate applications and IT processes with the network. Vendors, operators, and researchers have seen great opportunities to apply SDN to address a wide variety of networking issues, such as resource access control, routing optimization, security enforcement, traffic engineering, failure recovery, quality of service (QoS) assurance, network debugging, traffic monitoring, and resource allocation. At the same time, SDN is still under active development. Many great challenges need to be addressed to make SDN a mature technology. This panel gathers experts from both industry and academia to discuss the directions and challenges of SDN. We expect to have a highly interactive session among the panelists and the audience to shed lights on the research and development in the exciting area of SDN.

H. Jonathan Chao is Department Head and Professor of Electrical and Computer Engineering at Polytechnic Institute of New York University, Brooklyn, NY, where he joined in January 1992. He has been doing research in the areas of data center network designs, terabit switches/routers, network security, network on chip, and biomedical devices. He holds 45 patents with 11 pending and has published more than 200 journal and conference papers. He has also served as a consultant for various companies, such as Huawei, Lucent, NEC, and Telcordia.

During 2000 - 2001, he was Co-Founder and CTO of Coree Networks, NJ, where he led a team to implement a multi-terabit MPLS (Multi-Protocol Label Switching) switch router with carrier-class reliability. From 1992 to 1999, he taught short courses 3 times a year in the subjects of SONET, ATM, IP, MPLS, switche/router designs, to industry people through UC Berkeley and Oxford University's continuing education programs. From 1985 to 1992, he was a Member of Technical Staff at Telcordia, where he was involved in transport and switching system architecture designs and ASIC implementations, such as the world's first SONET-like Framer chip, ATM Layer chip, Sequencer chip (the first chip handling packet scheduling), and ATM switch chip. From 1977 to 1981, he was a Senior Engineer at Telecommunication Labs of Taiwan performing circuit designs for a digital telephone switching system.

Prof. Chao is a Fellow of the IEEE for his contributions to the architecture and application of VLSI circuits in high-speed packet networks. He received the Telcordia Excellence Award in 1987. He is a co-recipient of the 2001 Best Paper Award from the IEEE Transaction on Circuits and Systems for Video Technology. He coauthored three networking books, Broadband Packet Switching Technologies—A Practical Guide to ATM Switches and IP Routers (New York: Wiley, 2001), Quality of Service Control in High-Speed Networks (New York: Wiley, 2001), and High-Performance Switches and Routers (New York: Wiley, 2007).

Prof. Chao received his B.S. and M.S. degrees in electrical engineering from National Chiao Tung University, Taiwan, and his Ph.D. degree in electrical engineering from Ohio State University.

Dr. Tzi-cker Chiueh is currently the General Director of the Cloud Computing Center for Mobile Applications (CCMA) at ITRI and Professor in the Computer Science Department of Stony Brook University. He received his BSEE from National Taiwan University, MSCS from Stanford University, and Ph.D. in CS from University of California at Berkeley in 1984, 1988, and 1992, respectively.

He received an NSF CAREER award, an NYNEX Excellence in Education Award in 1996, and several best paper awards, including that from the 1999 IEEE Hot Interconnect Symposium, the 25th Annual Computer Security Applications Conference and the 2008 IEEE International Conference on Data Engineering (ICDE). Before joining ITRI, Dr. Chiueh served as the director of Core Research in Symantec Research Labs. Dr. Chiueh has published over 180 technical papers in referred conferences and journals. His current research interest lies in storage systems, wired/wireless networking, and software security.

Dr. Wu Chou is VP, Chief IT Scientist, and Head of Huawei Shannon (IT) Lab, USA. He is an IEEE Fellow, a renowned expert in the field of IT, computing, networking, Internet/Web, communication, signal processing, speech and natural language processing, unified communication, and IT software.

He has over 20+ years of professional career in leading R&D organizations. Before joining Huawei, he was Director of R&D at Avaya. He graduated from Stanford University in 1990 with four advanced degrees in science and engineering. He joined AT&T Bell Labs after obtaining his Ph.D. degree in electrical engineering and continued his professional career from AT&T Bell Labs to Lucent Bell Labs and Avaya Labs before joining Huawei. In his role at Huawei, he leads the global Huawei Shannon (IT) Lab in its research and innovation in the fast moving IT area.
