CAPWAP describes three different scenarios for the relocation of WLAN func-
tions to the central WLAN Controller.
Remote MAC: In this case, all of the WLAN functions are transferred from
the Access Point to the WLAN Controller. Here, the Access Points only
serve as "extended antennas" without independent intelligence.
Split MAC: With this variant, only a portion of the WLAN functions are
transferred to the WLAN Controller. Normally, realtime applications will
continue to be processed in the Access Point; the non-realtime applica-
tions are processed via the central WLAN Controller.
