Ivan Pepelnjak from ipSpace.net comments:
When talking about OpenFlow and the whole idea of controller-based networking, people usually say “well, it’s nothing radically new, we’ve been using wireless controllers for years and they work well, so the OpenFlow ones will work as well.”
Unfortunately the comparison is totally misleading.
A common comparison that I hear due to the overlap of a “controller”. Aggregating WLAN devices is easy, jamming entries into a CAM table is a harder.
