Optical networking forms the foundation of the global network infrastructure, hence the planning and design of optical networks is crucial to the operation and economics of the Internet and its ability to support critical and reliable communication services. We consider two classical yet notoriously difficult network design problems, routing and wavelength assignment (RWA) and traffic grooming. We show that, by exploiting domain-specific information regarding the problem structure, it is possible to develop decompositions and new mathematical formulations to solve these problems to optimality or within a small (and known) optimality gap. The new formulations run several orders of magnitude faster and scale to ring and mesh network topologies encountered in practice.

George N. Rouskas is a Professor of Computer Science at North Carolina State University and an IEEE Fellow. He ] received an undergraduate degree in Computer Engineering from the National Technical University of Athens, Greece, and the M.S. and Ph.D. degrees in Computer Science from the College of Computing, Georgia Institute of Technology. His research interests include network architectures and protocols, optical networks, network design, and performance evaluation. He is co-editor of the book "Next-Generation Internet Architectures and Protocols" (Cambridge University Press, 2011), author of the book "Internet Tiered Services" (Springer, 2009), and co-editor of the book "Traffic Grooming for Optical Networks" (Springer 2008). He is founding co-editor-in-chief of the Optical Switching and Networking Journal and he has served on the editorial boards of IEEE/ACM Transactions on Networking, Computer Networks, and Optical Networks. He was the TPC co-chair for ICCCN 2011, and he has served as TPC or general chair for several conferences, including the IEEE GLOBECOM 2010 ONS Symposium, BROADNETS 2007, IEEE LANMAN 2004 and 2005, and IFIP NETWORKING 2004. He is the recipient of a 1997 NSF CAREER Award, the 2004 ALCOA Foundation Engineering Research Achievement Award, and the 2003 NCSU Alumni Outstanding Research Award, and he was inducted in the NCSU Academy of Outstanding Teachers in 2004. He also served as a Distinguished Lecturer for the IEEE Communications Society in 2010-11.
