With the aerohive solution this is done thru cooperative control amongst the aps that are RF neighbors with each other. Here is article that discusses the protocols that aerohive uses to accomplish this.

We are seriously considering replacing our Aruba infrastructure in favor of a distributed model. We are having controller issues this academic year and the appeal of a controller-less model is strong. It feels like I am coming full circle to where I was six years ago. Though I know its not exactly the same, I went back to the thin vs thick debates in the archives. A few things stood out to me as considerations: One concern was vendor longevity. Another was whether or not the thick AP model would be able to keep up with the controller based architecture. An advantage of the controller based architecture that stood out to me was central processing, specifically regarding key exchange. Are these points still valid concerns? If your administration asked you to consider a distributed architecture, what other (vendor-neutral) concerns would you have? Thanks, in advance, for your opinions!
