SUMMARY:Bandwidth calendaring: a new SDN service
DESCRIPTION:\n\n\nAbstract:\nSoftware Defined Networking paves the way for
 new services that enable better utilization of network resources. Bandwidth
 Calendaring (BWC) is a typical such example that exploits knowledge about
 future traffic\, to optimally pack the arising demands over the network. We
 consider a generic BWC instance\, where a network operator has to
 accommodate at minimum cost demands of predetermined\, but time-varying\,
 bandwidth requirements that can be scheduled within a specific time window.
 By exploiting the structure of the problem\, we propose low complexity
 methods for the decomposition of the original Mixed integer problem into
 simpler ones. Our numerical results reveal that the proposed solution
 approach is near-optimal and outperforms standard methods based on linear
 programming relaxations and randomized rounding by more than
 20%.\n\n\nBiography:\nLazaros Gkatzikis
 (S’09–M’13) obtained the
 Ph.D. degree in computer engineering and communications from the University
 of Thessaly\, Volos\, Greece. Currently\, he is a Research Staff Member at
 Huawei France Research Center\, Paris\, France. In the fall of 2011\, he
 was a Research Intern at the Technicolor Paris Research Laboratory. He has
 been a Postdoctoral Researcher in the team of Prof. L. Tassiulas in Volos\,
 Greece (2013) and at the KTH Royal Institute of Technology\, Stockholm\,
 Sweden (2014) working with Associate Prof. C. Fischione. His research
 interests include network optimization\, mechanism design\, and network
 performance analysis.\n\n\n
