Optical Networks
sunday, may 19, 14.15-18.00

In this half-day tutorial, we will present the current state of the art in optical networks. We will begin by discussing the various optical devices used in optical networks. Then, we will present wavelength-routed networks, which is currently the dominant architecture for optical networks. We will discuss wavelength allocation policies, calculation of call blocking probabilities, and network optimization techniques. Subsequently, we will focus on the various protocols that have been proposed for wavelength-routed networks. Specifically, we will present a framework for IP over optical networks, GMPLS, LDP and CR-LDP with extensions for optical networks. Finally, we will conclude our tutorial with a discussion on Optical Burst Switching (OBS), a new emerging technology.

Harry PerrosHarry G. Perros received the B.Sc. degree in Mathematics in 1970 from Athens University, Greece, the M.Sc. degree in Operational Research with Computing from Leeds University, UK, in 1971, and the Ph.D. degree in Operations Research from Trinity College, Dublin, Ireland, in 1975. From 1976 to 1982 he was an Assistant Professor in the Department of Quantitative Methods, University of Illinois at Chicago. In 1979 he spent a sabbatical term at INRIA, Rocquencourt, France. In 1982 he joined the Department of Computer Science, North Carolina State University, as an Associate Professor, and since 1988 he is a Professor. During the academic year 1988-89 he was on a sabbatical leave of absence first at BNR, Research Triangle Park, North Carolina, and subsequently at the University of Paris 6, France. Also, during the academic year 1995-96 he was on a sabbatical leave of absence at Nortel, Research Triangle Park, North Carolina.

He has published extensively in the area of performance modeling of computer and communication systems, and has organized several national and international conferences. He also published a monograph entitled "Queueing networks with blocking: exact and approximate solutions," Oxford Press, as well as a book entitled "An Introduction to ATM Networks," John Wiley. He is the chairman of the IFIP W.G. 6.3 on the Performance of Communication Systems. He has offered several professional courses in the areas of ATM Networks and Optical Networks.


George RouskasGeorge N. Rouskas received the Diploma in Computer Engineering from the National Technical University of Athens (NTUA), Athens, Greece, in 1989, and the M.S. and Ph.D. degrees in Computer Science from the College of Computing, Georgia Institute of Technology, Atlanta, GA, in 1991 and 1994, respectively. He is an Associate Professor in the Department of Computer Science, North Carolina State University, where he received tenure one year early. During the 2000-2001 academic year he spent a sabbatical term at Vitesse Semiconductor, Morrisville, NC, and in May and June 2000 he was an Invited Professor at the University of Evry, France.

He is a recipient of a 1997 NSF Faculty Early Career Development (CAREER) Award, and a co-author of a paper that received the Best Paper Award at the 1998 SPIE conference on All-Optical Networking. He also received the 1995 Outstanding New Teacher Award from the Department of Computer Science, North Carolina State University, and the 1994 Graduate Research Assistant Award from the College of Computing, Georgia Tech. He was a co-guest editor for the IEEE Journal on Selected Areas in Communications, Special Issue on Protocols and Architectures for Next Generation Optical WDM Networks, published in October, 2000, and is on the editorial boards of the IEEE/ACM Transactions on Networking, Computer Networks, and the Optical Networks Magazine. He has offered several professional courses in the areas of TCP/IP, the Internet, and Optical Networks.
