Mesh software architecture

Access points within a mesh network operate as either a root access point (RAP) or a mesh access point 
(MAP).

All mesh access points are shipped configured as a MAP. You must reconfigure the mesh access point 
for it to be a RAP. At least one RAP must exist in all mesh networks.

RAPs have wired connections to their controller, and MAPs have wireless connections to their controller.

MAPs communicate among themselves and back to the RAP using wireless connections over the 
802.11a radio backhaul. MAPs use the Cisco Adaptive Wireless Path Protocol (AWPP) to determine the 
best path through the other mesh access points to the controller. 

All the possible paths between the MAPs and RAPs form the wireless mesh network.
