This is great, Ben. Just a few minor things:

Do you think it's worth mentioning that we now set the DSCP bits so that people can prevent some of this in their "core" switches and routers?

> + In-band control must be implemented regardless of whether the

Do you think it's worth making these bullet points to match the previous lists?
> +Open vSwitch implements in-band control as "hidden" flows, that is,
> +flows that are not visible through OpenFlow, and at a higher priority
> +than wildcarded flows can be set up by through OpenFlow. This is done
You can drop either the "by" or "through".
Thanks,
