Bridging Applications and Networks

The digital ecosystem is shaped by the widespread use of cloud computing for online application where the content is delivered to the users via Internet. The traditionally, the application developers assume that the underlying network has unlimited bandwidth and the latency is non-existent. On the other hand, network does not care what applications or content it is delivering. This leads to an inevitable divide between the network and the application, and inefficient use of resources.

In this talk, I will present my current work and future aspirations for efficient resource utilization in the cloud, in the network and at the edge of the network for the end-users. First, I will introduce a system that schedules the downlink traffic of mobile phone users by leveraging the data on past user behavior. Then, I will present a network-aware service selection algorithm for loosely-couple multi-tier applications in distributed clouds. Finally, I will talk about my research agenda that comprises the use of Software Defined Networks for the efficient use of network resources.

Utku is a Member of Technical Staff in Alcatel-Lucent Bell Labs in Antwerp, Belgium. He received his B.S. degree in Telecommunications Engineering with honors from Sabancı University, Turkey in 2004, and his M.S. and Ph.D. degrees from the Electrical, Computer and Systems Engineering Department of Rensselaer Polytechnic Institute, Troy, NY, USA in 2005 and 2009, respectively. From 2009 to 2010, he was a post doctoral researcher with Inria Sophia Antipolis. His research interests include network systems, cloud computing, and distributed and mobile systems. My work involves design and implementation of new algorithms and systems that leverage the analysis of data.
