Oscar Gonzalez de Dios

Óscar González de Dios received the PhD with honors form U. of Valladolid in 2012 and his MS, also from U. of Valladolid, in 2000 in Telecommunications Engineering. In 2000 he joined Telefónica Research and Developement, where he worked for several years in the development and testing of telephony applications and interactive voice-response platforms. In 2005 he joined the Advanced Network Planning department in Telefonica Research and Development in Madrid to start working in the analysis and performance evaluation of optical networks. Since then, he has been involved in numerous R&D European projects, (NOBEL, NOBEL II, STRONGEST , ePhoton One+, AGAVE, BONE, BANITS2, RUBENS, ONE). He has co-authored more than 40 research papers in international conferences and magazines. He is currently active in IETF CCAMP and PCE WGs, as well as ITU-T Study group 15. He is co-author of several IETF drafts. He is currently a Technology Specialist in the Core Network Evolution team, part of the Global CTO Unit. Recent work has included the design of the interconnection of photonic Networks in Telefónica. His main research interests include Photonic Networks, Flexi-grid, Inter-domain Routing, PCE, OBS, automatic network configuration, End To End MPLS, TCP performance and recently SDN.
