Abstract: Software-Defined Networking (SDN) is an emerging network architecture decoupling the network control and forwarding functions, and it enables the network elements to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. SDN is ideal for the bandwidth hungry and dynamic nature of today’s applications, since it permits through a logically centralized controller to reconfigure instantaneously the network, thus exploiting the network capacity more efficiently than distributed routing protocols. Looking at classical networking problems through the angle of centralization brings very challenging and new online network optimization problems. These problems were not considered when everything was done at network planning phase with no hard time constraints. This talk gives an introduction to this new domain and presents a few contributions on fast connection setup and network re-optimization.
Biography: Dr. Jérémie Leguay received his a Ph.D. degree from Pierre & Marie Curie University in Paris on ad hoc and delay tolerant networks. He was awarded the Thales Ph.D Prize for this work in 2007. From 2007 to 2009, he worked as a Research Engineer at Thales Communications and extended his research activities to vehicular and wireless sensor networks. From 2009 to 2014, he was responsible for the Research & Technology lab on networked systems at Thales Communications & Security where he especially developed activities on mobile wireless networks and software-defined networks. He joined Huawei’s French research Center in November 2014 to lead the traffic and network optimization team. His current research interests are protocol design and network optimization for fix and mobile environments.
