From the YouTube description:
This tech talk is a guest keynote given at Ericsson Research by Scott Shenker, Professor at the University of California in Berkeley, Vice President of the International Computer Science Institute, and co- founder of Nicira Networks. Scott discusses the intellectual and practical weakness of today's foundations of networking, and argues that they can be strengthened by introducing cleaner abstractions, rather than managing the ever-growing complexity of protocols. Software-Defined Networking (SDN) is an instantiation of such abstractions that promises to create a more evolvable architecture for the Internet.
If you're into networking or computer-science theory, you will find this fascinating.
