Luis M. Contreras

Luis M. Contreras completed a six-year Telecom Engineer degree at the Universidad Politécnica of Madrid (1997), and holds an M. Sc. on Telematics from the Universidad Carlos III of Madrid (2010). In 1997 he joined Alcatel Spain taking several positions (R&D, standardization, product development and customer engineering) in both wireless and fixed network fields. In 2006 he joined the Network Planning department of Orange Spain (France Télécom group) taking responsibilities on the IP backbone planning. Between 2002 and 2010 he was also adjunct lecturer at the Telematics department of the Universidad Carlos III, where he is currently a Ph.D. student. Since August 2011 he is part of Telefónica I+D / Telefónica Global CTO, working on SDN, transport networks and their interaction with cloud and distributed services. He has participated in the FP7 projects GEYSERS and XIFI. In July 2012 he co-organized the International Workshop on Cross-Stratum Optimization for Cloud Computing and Distributed Networked Applications, co-located with the 10th IEEE International Symposium on Parallel and Distributed Processing with Applications (ISPA 2012), Leganés, Spain. He is an active contributor to the ONF and the IETF.

- Support to distinct groups within Telefónica (Procurement, Regulation, technical departments of local operations in Europe and Latam, transversal organizations, etc).
- Definition and update of global guidelines for network architecture in the transport area (IP, transmission, mobile backhaul, etc), and contribution to the network strategy plan in the transport area.
- Techno-economic analysis of network evolution scenarios.
- Frequent contact with vendors for technological advise, product roadmap and upgrade, strategy review, etc.

• Innovation (medium- and long-term):
- Research on Software Defined Networks (SDN), transport networks (IP, transmission, mobile backhaul), and their interaction with cloud and distributed services.
- Active contribution to standardization bodies like IETF and ONF.
- Participation in the EU-funded projects such as FP7 GEYSERS and FI-PPP XIFI.
- Collaboration with vendors, research centers and universities for developing new ideas and research proposals.
