September 23, 2021 - Krishan Sabnani

My Research Journey: Softrouter, Protocols, and Wireless DDoS

Location: Zoom - See link in Abstract
Time: 10:45 am - 12:00 pm


Krishan Sabnani will present a summary of his networking research. His work on Softrouter is a breakthrough in Internet re-design. The main idea behind this work was to separate control functions and complex software from the forwarding portions on Internet routers. This work made it possible for forwarding technologies (e.g., different link layers and switching protocols) to evolve and be deployed independently from control protocols (e.g., routing, security). This contribution is a precursor to the current Software Defined Networking (SDN) revolution. Sabnani will also summarize his work on protocol conformance testing and a new class of DoS attacks that can be launched against cellular networks.
