Dimitri Papadimitriou received an M.S.degree in physics from the UniversitLibre de Bruxelles and an M.S.degree in Computer Science from the Universitde Liège. After one year of collaboration on Network Protocols R&D at the Research Center of Namur, he worked for 3 years in the design and evaluation of packet (IP/MPLS), Ethernet, and circuit (SDH/optical) transport networks as well as their compliance to IETF/ITU standards. In 2000, he joined Alcatel as a Expert Research Engineer in the Network Technology and Analysis team of the Network Strategy Group. In 2004, he joined the Packet-Transport Interworking (PTI) team of the Research and Innovation (R&I) CTO department. His current areas of interest are focused on distributed IP control planes, IP routing protocols as well as Traffic Engineering and QoS mechanisms for connectionless and flow oriented technologies. Dimitri Papadimitriou is actively involved in the standardization activities of the Internet Engineering Task Force (IETF) Routing Area where he edits and co-authors numerous working group documents on Generalized/Multi-Protocol Label Switching (G/MPLS)-based control planes and related protocol aspects. He also authored numerous technical papers on routing and recovery techniques for sub-IP networks. He is currently involved in the EuroNGI (Design and Engineering of the Next Generation Internet) Network of Excellence and leading the GMPLS control plane architecture as well as the exploitation and dissemination activities of the ITEA TBONES European project.
