Matt Oswalt of Keeping It Classless comments:
In the last post, I introduced you to the concept of control plane abstraction, specifically the OpenFlow implementation. I talked about how OpenFlow allows us to specify the flows that we want to be programmed into the forwarding plane, from outside the forwarding device itself. We can also match on fields we typically don’t have access to in traditional networking, since current hardware is optimized for destination-based forwarding.
In this post, I plan to cover quite a few bases. The goal of this post is to address the main concepts of OpenFlow’s operation, with links to find out more. With this post, you’ll be armed with the knowledge of what OpenFlow does and doesn’t do, as well as resources to dive even deeper.
A seriously deep dive into OpenFlow 1.3. If you are in networking today, you *need* to read this post.
