Abstract

This talk will highlight recent work, as well as future research directions, in Wavelength Division Multiplexing (WDM) networks. It is motivated by the design of high capacity optical networks for the Next Generation Internet (NGI). An important goal of the architecture for the NGI is to reduce the cost of electronics in the network by supporting Internet traffic directly over the WDM layer (IP over WDM). Some of the issues discussed include: network reconfiguration algorithms that improve network capacity by altering the network logical topology in response to changes in traffic conditions; traffic grooming algorithms to minimize the cost of electronics in the network; algorithms for joint electronic and optical layer protection; and optical flow switching algorithms for bypassing the electronics in the network.

Bio

Eytan Modiano received his B.S. degree in Electrical Engineering and Computer Science from the University of Connecticut at Storrs in 1986 and his M.S. and PhD degrees, both in Electrical Engineering, from the University of Maryland, College Park, MD, in 1989 and 1992 respectively. He was a Naval Research Laboratory Fellow between 1987 and 1992 and a National Research Council Post Doctoral Fellow during 1992-1993 while he was conducting research on security and performance issues in distributed network protocols.

Between 1993 and 1999 he was with the Communications Division at MIT Lincoln Laboratory where he designed communication protocols for satellite, wireless, and optical networks and was the project leader for MIT Lincoln Laboratory's Next Generation Internet (NGI) project. Since 1999, he has been a member of the faculty of the Aeronautics and Astronautics Department and the Laboratory for Information and Decision Systems (LIDS) at MIT, where he conducts research on communication networks and protocols with emphasis on satellite and hybrid networks, and high speed networks.
