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.

This volume of the Lecture Notes in Computer Science series contains the set of papers accepted for presentation at the 5th International Workshop on Quality of future Internet Services (QofIS 2004) and at the two one-day workshops - locatedwithQofIS2004, namelythe1stInternationalWorkshoponQoSRouting (WQoSR 2004) and the 4th International Workshop on Internet Charging and QoS Technology (ICQT 2004). QofIS 2004, the ?fth international event, was organized under the umbrella of the E-NEXT Network of Excellence on Emerging Networking Experiments and Technologies, which started its activities in January 2004. QofIS 2004 took place on September 29 30, 2004 at the Telef onica premises in Barcelona, and was arranged by the Universitat Polit ecnica de Catalunya (UPC). QofIS 2004 in Barcelona followed the highly successful workshops in Stockholm in 2003, Zuric ] h in2002, Coimbrain2001, andBerlinin2000.ThepurposeofQofIS2004, asofall QofIS events, was to present and discuss design and implementation techniques for providing quality of service in the Internet.
