**** Columbia Network Research Group Seminar **** Title: Next Generation Networks: The New Public Network Speaker: Richard D. Gitlin Visiting Professor of Electrical Engineering Columbia University When: Wednesday, October 4, 10 am Where: Interschool Lab, CEPSR Building, 7th floor Columbia University Abstract: There is no longer any debate that wide-area networks, based on packet technology, will emerge as a compelling alternative to the Public Switched Telecommunications Network (PSTN). This next-generation network will be a multi-service, high performance network, will support rapid service creation, and will provide a quality of service that is matched to the applications it carries. Extraordinary rates of progress in semiconductor, photonic, and software technologies have fueled an unparalleled level of expectations about this converged voice and data, wireline and wireless "network of networks." We will describe the means by which quality of service, security, and network management will be provided in the next-generation network. The expanding ubiquity of the Internet Protocol (IP) is driving convergence in desktop applications that will be voice, data, and, ultimately, video oriented. These applications will need assurances from the integrated, converged network that the performance they receive is consistent and at appropriate service levels. This imposes stringent requirements on quality of service (QoS), as well as on security, since the applications will require confidentiality and isolation from one another. Given these complex demands, more than ever before there is a need for efficient network management. This will require not only overall network management, but also management on a per customer, per application, or per perhaps even on a per flow basis. This presentation first describes the fast pace of technology evolution that is driving the realization of innovative next-generation networks. It then addresses the technological advances that will be used to achieve the QoS, security, and network management requirements for demanding applications such as Voice over Packet, Virtual Private Networks, and high-speed Remote Data Access. Bio: Dr. Richard D. Gitlin is Visiting Professor of Electrical Engineering at Columbia University. Before assuming this position, he was with Lucent Technologies for more than thirty years, where he held several executive positions. He was the Chief Technical Officer and Vice President of R&D, of the Data Networking Systems Business Unit, where he was responsible for product development, architecture and systems engineering, standards, and advanced development for all data networking products. >From 1995 to 1998 he was Senior Vice President for Communication Sciences Research at Bell Labs, Lucent Technologies. Throughout his career he has conducted and led pioneering research and development in digital communications and networking that has resulted in many innovative products including: the industry leading ATLANTA ATM Chipset, Globeview --- the world's first 20 gigabit/sec ATM switch, wire-speed and quality of service [QoS]-aware IP switches, multicode technology for CDMA wireless data (IS-95B), and the record-setting BLAST fixed-wireless loop system based on advanced spatial domain (smart antenna) processing. Earlier in his career he led the team that pioneered the V.32/V.34 voice-band modems, and in 1986 he was a co-inventor of the DSL technology. He is the co-recipient of three prize paper awards including the 1995 IEEE Communications Society's Steven O. Rice Award for the best original paper published in the IEEE Transactions on Communications, the 1994 IEEE Communications Society's Frederick Ellersick Award for the best paper published in the IEEE Communications, and the 1982 Bell System Technical Journal Award for the best paper in communications science. Dr. Gitlin is the co-author of the text Data Communications Principles, more than 95 technical papers, numerous conference papers and keynote presentations. He holds 43 patents in the area of data communications, digital signal processing, wireless systems, and broadband networking. He is a Fellow of the IEEE and is also a Bell Laboratories Fellow. Dr. Gitlin has served as Chair of the Communication Theory Committee of the IEEE Communications Society, as a member of the COMSOC Awards Board, as Editor for communication theory of the IEEE Transactions on Communications, as a member of the Board of Governors of the IEEE Communications Society, and a member of the Nominations and Elections Board. He has served on the Advisory Committee for Computer Science and Engineering (CISE) of the National Science Foundation and the Industrial Advisory Board of the EE/CS Department of University California (Berkeley). He has been an Adjunct Professor of Electrical Engineering at Princeton University. He currently serves on the Editorial Board of the Bell Labs Technical Journal, Mobile Networks and Applications, and the Journal of Communications Networks (JCN). Dr. Gitlin received the D. Eng. Sc. Degree from Columbia University in 1969.
