This post proeedings volume contains a selection of research contributions presented at FITraMEn 2008, held during December 11-12, 2008 in Porto, Portugal. The papers contained in this book provide a general view of the ongoing research on traffic management and traffic engineering in the Euro-NF Network of Excellence, and give a representative example of the problems currently investigated in this area, that spans topics such as bandwidth allocation and traffic control, statistical analysis, traffic engineering, and optical networks and video communications.
