CISCO-LWAPP-TSM-MIB

This MIB is intended to be implemented on all those
        devices operating as Central controllers, that
        terminate the Light Weight Access Point Protocol
        tunnel from Cisco Light-weight LWAPP Access Points.
        
        Network management stations learn the audio/video
        traffic quality observed on WLANs through this MIB.
        
        The relationship between CC and the LWAPP APs
        can be depicted as follows:

        The LWAPP tunnel exists between the controller and
        the APs.  The MNs communicate with the APs through
        the protocol defined by the 802.11 standard.
        
        LWAPP APs, upon bootup, discover and join one of the
        controllers and the controller pushes the configuration,
        that includes the WLAN parameters, to the LWAPP APs.
        The APs then encapsulate all the 802.11 frames from
        wireless clients inside LWAPP frames and forward
        the LWAPP frames to the controller.
        
        This MIB provides the information about the per-client
        /per-AP packet latency, packet jitter, packet loss and
        roaming time in the network which does affect quality 
        of audio/video traffic. These parameters are called 
        Traffic Stream Metrics. When TSM collection is enabled 
        on all 802.11a/802.11b interfaces, the metrics are 
        collected by controller from AP in every 90 seconds 
        window.
        
        	Information provided by this MIB can be used by the
        NMS applications to present measurements of audio and 
        video traffic quality. 
        
                           GLOSSARY
        
        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.
        
        Central Controller ( CC )
        
        The central entity that terminates the LWAPP protocol
        tunnel from the LWAPP APs.  Throughout this MIB,
        this entity is 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
        Central Controller.
        
        Mobile Node ( MN )
        
        A roaming 802.11 wireless device in a wireless
        network associated with an access point.
        
        Traffic Stream Metrics (TSM)
        
        These  are parameters like the per-client / per-AP
        packet latency, packet jitter, packet loss and roaming
        time in the network, which does affect quality of
        audio/video traffic.  These statistics are collected
        to study and characterize the pattern of data
        traffic and perform appropriate management tasks to
        regulate the same for the smooth functioning of the
        network. 
        
        Channel Utilization (CU)
        The Channel Utilization is defined as the percentage of time,
        the QAP sensed the medium was busy, as indicated by
        either the physical or virtual carrier sense (CS) mechanism.
        
        Picc
        Picc is the time consumed by AP for receiving frames
        not destined to itself on a particular Radio interface
        from co-channel APs and Clients.
        
        Pib
        Pib is the time consumed by AP for receiving frames on 
        a particular Radio interface which are not correctly de-modulated.
