This book constitutes the refereed proceedings of the 11th International IFIP-TC6 Conference on Optical Network Design and Modeling, ONDM 2007, held in Athens, Greece, in May 2007.

The 41 revised full papers presented together with 14 invited papers were carefully reviewed and selected from over 90 submissions. The papers address all recent advances in the design, modeling and implementation of optical networks, including novel switching schemes and paradigms, network optimization and design, new concepts for link and control layer protocols, advanced network subsystems and node architectures, and network inter-working schemes.
