On the Web: Openfabric at IPspace

I was over at ipspace to talk to Ivan and several other folks about openfabric. This is one of those situations where… Well, the algorithm openfabric uses to calculate fabric location has changed slightly in the last week. Welcome to the world of networking technology. 🙂

As always, we started with the “what’s wrong with what we have right now, like using BGP as a better IGP” question, resulting in “BGP is becoming the trash can of the Internet”. You can probably guess the next set of intro questions: “Do we need policies and traffic engineering in a high-speed data center fabric?” Finally, we got to discussing OpenFabric, starting with how OpenFabric uses link-state database to modify IS-IS flooding behavior and thus reduces the total amount of flooding in a data center fabric. Next step: how do you know where it’s safe to reduce flooding? You have to figure out whether you’re a leaf or spine, and there are two ways in OpenFabric to solve that challenge.
