DOT: Distributed OpenFlow Testbed

Abstract: With the growing adoption of Software Defined Networking (SDN) technology, there is a compelling need for an SDN emulator that can facilitate experimenting with new SDN solutions. In this context, Mininet is the de-facto standard emulator for prototyping a network on a single machine. It allows users to create, control, and customize an emulated network on which they can run and test new control applications like routing, traffic engineering, etc. However, Mininet cannot scale for large networks and high traffic volumes. To address these limitations, at the University of Waterloo we developed Distributed OpenFlow Testbed (DOT), a highly scalable emulator for SDN. DOT distributes the emulated network across several physical machines to provide guaranteed CPU time, bandwidth and network latency for the emulated components (i.e., switches, hosts and links). It can scale with the network size and traffic volume. It also has built-in support for configuring and monitoring the emulated components from a central point. Moreover, DOT can emulate a wider range of network services compared to other publicly available SDN emulators and simulators.

Biography: Raouf Boutaba is a Professor of Computer Science at the University of Waterloo. He is the founding Editor in Chief of the IEEE Transactions on Network and Service Management (2007-2010), and on the editorial board of several other journals. He served as the general or technical program chair for a number of international conferences. His research interests are in the areas of network and service management. He has published extensively in these areas and received several journal and conference Best Paper Awards such as the IEEE 2008 Fred W. Ellersick Prize Paper Award. He also received several other recognitions such as the Premier's Research Excellence Award, Industry research excellence Awards, fellowships of the Faculty of Mathematics, of the David R. Cheriton School of Computer Science and outstanding performance awards at the University of Waterloo. He has also received the IEEE Communications Society Hal Sobol Award and the IFIP Silver Core in 2007, the IEEE Communications Society Joe LociCero and the Dan Stokesbury awards in 2009, and the IEEE Communications Society Salah Aidarous award in 2012. He served as a distinguished lecturer for the IEEE Computer and Communications Societies. He is fellow of the IEEE and fellow of the Engineering Institute of Canada and a recipient of the 2014 McNaugthon Gold Medal.
