Networking is NOT Free: Lessons in Network Design

This presentation will be an in-depth critique of the existing OpenStack networking approach, with a focus on how the Nova network controller is more of a hindrance than a help. We will also discuss the changes in Quantum's functionality required to close the gap, and alternative solutions. How can we make networking in OpenStack robust, high performance, and fault tolerant? What do typical large scale networks look like and what lessons can we learn from them? Is there an approach to networking we can take that is the same with a handful of servers as it is with hundreds of racks? 

Speakers: Dan Sneddon
