TitleBringing Network Programmability to Mobile Networks  


The expectations on 5G networks is quite high in terms of data rates, latency, mobility, energy efficiency, and service agility. Optimizing wireless/mobile networks in any one of these dimensions falls short of meeting the peak targets in other dimensions. Mobile network programmability will be a key component in the 5G world to provide the right level of trade offs for an individual service and/or subscriber, while attaining a good degree of statistical multiplexing over the physical substrate and resources. In my talk, I will first overview the architectural journey we took from 2G to 4G mobile data networks in light of 3GPP standards. After highlighting some of the key pain points in the current LTE architecture towards next generation services, I will focus on two narrow problems in the context of ultra dense small cell architectures, where small cells share the same wireless front-haul. The first problem investigates whether the network programmability brings about any performance benefits over the smart end point solutions. The second problem looks into the problem of small cell topology control based on peak demand estimation.



Ulas C. Kozat is a senior member of technical staff at Huawei R&D in Santa Clara, CA. At Huawei, he leads several R&D and open source projects in the areas of Software Defined Mobile Networks and Network Function Virtualization.  Previously, he worked as principal research scientist at Argela USA in Sunnyvale, CA and as principal research engineer at DOCOMO Innovations (formerly DOCOMO USA Labs) in Palo Alto, CA. He received his Ph.D. from the University of Maryland, College Park, his M.Sc. from the George Washington University, Washington DC, and his B.Sc. from the Bilkent University, Ankara, all in Electrical & Electronics/Computer Engineering. Dr. Kozat is a senior member of IEEE. He has published extensively and holds several patents in the areas of network modeling; cross-layer optimization; and architecture, protocol, algorithm design.
