Interesting network features of your Debian system

Networking is still very much a domain in which big proprietary computing equipments dominate. The Linux kernel, though, has some very neat networking features, and is increasingly being used to replace those systems with something more open and more adaptable to "strange" needs. During this talk we will explore some less-known Linux networking features, such as NBMA networks over unbound GRE tunnels, policy routing, or anycast that will allow systems administrators to take control of the network, and even sometimes make something slightly crazy with it, and make some of those networking people, who only trust those closed machines on which they're certified, a bit (or a lot) nervous.
