Let's say a client Wireless IP phone is connected (sending UDP data) to a Ruckus AP1 while making a phone call he is roaming out of AP1s coverage area and roaming into AP2s coverage area.
Using the re-association frame (never used in the real world) AP1 would buffer the data for the client and the protocol will then trigger AP2 requesting the buffered data being send over ethernet to AP2.
What protocol is Ruckus using for this? Is the roaming handeld by the Zonedirector and what if there is no Zonedirector? If only autonomous access points are installed, how would the roaming be handeld? What about 802.11r & 802.11k?
