NBAR - Network Based Application Recognition is
an intelligent classification engine that recognizes 
applications that are static (which use fixed TCP or
UDP port numbers), and stateful (which dynamically 
assign TCP or UDP port numbers).

Access Point ( AP )

An entity that contains an 802.11 medium access
control ( MAC ) and physical layer ( PHY ) interface
and provides access to the distribution services via
the wireless medium for associated clients.  

LWAPP APs encapsulate all the 802.11 frames in
LWAPP frames and sends it to the controller to which
it is logically connected to.

Central Controller ( CC )

The central entity that terminates the LWAPP protocol
tunnel from the LWAPP APs.  Throughout this MIB,
this entity also referred to as 'controller'.

Light Weight Access Point Protocol ( LWAPP ) 

This is a generic protocol that defines the
communication between the Access Points and the
controllers.

Mobile Node ( MN )

A roaming 802.11 wireless device in a wireless
network associated with an access point.

AVC - Application Visiblity and Control.
