Abstract

Software Defined Networks (SDNs) have opened up a new era for networking by decoupling the control and data planes. With a centralized controller, the process of updating networks becomes much more convenient when compared to traditional networks. However, even with SDNs, transitional network states during network updates may still cause problems. Such states may result in a breakdown of isolation guarantees or other critical constraints and this could lead to incorrect behavior or even security vulnerabilities. In this talk, I will provide a brief overview of SDN concepts and present a novel abstraction for network updates, inter-flow consistency, that can account for relationships and constraints among different flows during updates.

Speaker Bio

Rakesh Bobba specializes in security for distributed and networked systems. His research interests include access control models and mechanisms, key management, cryptographic protocols, and applied cryptography among others. His current research focus is on the security for critical cyber-physical infrastructures such as smart grids, cloud computing infrastructures and real-time systems. Prior to joining Oregon State he was at the University of Illinois, Urbana-Champaign (UIUC) as a Research Scientist at the Information Trust Institute (ITI) from 2010 to 2011, and as a Research Assistant Professor in the College of Engineering from 2012 to 2014 with appointments in ITI and ECE departments. His research is funded by NSF, DOE, ONR and AFOSR/AFRL.
