POX is more of a framework than a controller, so there's no universal architecture and no one place flows are stored (if they're stored at all). It's really up to individual components. l2_learning, for example, keeps MAC/port table per switch in an instance attribute. -- Murphy > On Fri, Oct 11, 2013 at 10:36 AM, Murphy McCauley <[email protected]> > wrote: > No component that comes with POX does routing in the sense of traditional IP > routers.
