ManSDN/NFV 2014 Keynote Talks
Speaker: Prof. Scott Shenker, UC Berkeley/ICSI, USA
Date: 11/20/2014, 09:00-10:30 AM
Room: Angra dos Reis B + C - Second Floor
Abstract: Software-Defined Networking (SDN) was developed over six years ago, amidst much hope and naivete. In this talk I will first discuss SDN's past, highlighting the follies of our youth. I will then discuss how a suitably updated SDN paradigm can meet the challenges of the future.
Bio: Scott Shenker (www.eecs.berkeley.edu) spent his academic youth studying theoretical physics but soon gave up chaos theory for computer science. Continuing to display a remarkably short attention span, his research over the years has wandered from performance modeling and networking to game theory and economics. Unable to focus on any single topic, his current research projects include software-defined networking, cluster programming models, genomic sequence aligners, and Internet architecture. Unable to hold a steady job, he currently splits his time between the UC Berkeley Computer Science Department and the International Computer Science Institute.

Abstract: The combination of the ongoing transition into all-IP networks (VoIP, LTE, IP DSLAMs) and the recent introduction of NFV and SDN pushes the industry into a massive shift in network design. The new architecture (which is currently still on the making) will be based on an execution of the network functions on commodity servers located in small cloud nodes distributed across the network, and the use of software define mechanisms that control the network flows. This is a major turning point in the evolution of networking as we know it that introduces, in additional to the rainbow of new opportunities, also the major technical barriers. In this talk I will describe the main characteristics of the Distributed Cloud Networking parading and the unique research questions it introduces. The first part will describe recent results related the actual placement of the virtual functions within the physical network. It turns out that this problem introduces a new generalization of the facility location problem not studied before. I’ll describe the new problem and a novel bi-criteria approximation algorithm for it. Then, in the rest of the talk I‘ll describe several important and interesting barriers and challenges in this area, and prospective research directions.
Bio: Prof. Danny Raz (http://www.cs.technion.ac.il/~danny/) is the director of the new Bell Labs site in Israel, focused on "distributed cloud networking", the new paradigm in which Cloud and SDN are used to virtualize many of the services currently deployed over dedicated hardware. Danny in on a Sabbatical from the Technion, Israel Institute of Technology, where he is a professor at the Computer Science Department, conducting research in the areas of network optimization with specific focus on network and cloud management.
