=== Centralized, Distributed, or Hybrid? ===
 
In <ref>http://ieeexplore.ieee{{Cite journal | doi=10.org1109/xpls/abs_allMNET.jsp2015.7166188| title=Software-defined wireless networking: Centralized, distributed, or hybrid?arnumber| year=71661882015| last1=Abolhasan| first1=Mehran| last2=Lipman| first2=Justin| last3=Ni| first3=Wei| last4=Hagelstein| first4=Brett| journal=IEEE Network| volume=29| issue=4| pages=32–38}}</ref> a new SDN architecture for [[Wireless distribution system|wireless distribution systems (WDNs)]] is explored that eliminates the need for multi-hop flooding of route information and therefore enables WDNs to easily expand. The key idea is to split network control and data forwarding by using two separate frequency bands. The forwarding nodes and the SDN controller exchange link-state information and other network control signaling in one of the bands, while actual data forwarding takes place in the other band.
