DESCRIPTION
"This MIB module provides network management
support for QoS on wireless LAN devices. All
objects defined in this MIB are listed (object
names have been modified to adopt Cisco MIB object
naming convention) in the IEEE 802.11E November
2001 draft. The original names of the objects
in the standard are included in the REFERENCE
clauses. The standard is still under development.
The standard IEEE 802.11E MIB can replace some of
the MIB objects in this MIB once the standard is
finalized.
GLOSSARY and ACRONYMS
Access point (AP)
Transmitter/receiver (transceiver) device
that commonly connects and transports data
between a wireless network and a wired network.
AIFS
Arbitration Interframe Space. It is one of the
five different IFSs defined to provide priority
levels for access to the wireless media. It shall
be used by QSTAs to transmit data type frames
(MPDUs) and management type frames (MMPDUs).
BSS
IEEE 802.11 Basic Service Set (Radio Cell). The
BSS of an AP comprises of the stations directly
associating with the AP.
CW
Contention Window. It is the time period between
radio signal collisions caused by simultaneous
broadcast from multiple wireless stations.
The contention window is used to compute the
random backoff of the radio broadcast. The IEEE
802.11b does not specify the unit for the time
period.
CWP Factor
Contention Window Persistence Factor. It indicates
the factor used in computing new CW values on every
15 unsuccessful attempt to transmit an MPDU or an
MMPDU of a traffic category. It is a scaling factor
in units of 1/16 ths.
IFS
Inter-Frame Space is the time interval between
frames. A STA shall determine that the medium
is idle through the use of the carrier sense
function for the interval specified. In other
words, the size of the IFS determines the length
of the backoff time interval of a device to the
medium. In this case, the medium is the radio
wave spectrum. The IEEE 802.11b standard does not
specify any unit for the time interval.
BSS
IEEE 802.11 Basic Service Set (Radio Cell). The
MAC
Medium Access Control. Layer 2 in the network
model.
MPDU
MAC protocol data unit. The unit of data exchanged
between two peer MAC entities using the services
of the physical layer (PHY).
MMPDU
Management type MAC protocol data unit.
MSDU
MAC service data unit. Information that is
delivered as a unit between MAC service access
points.
QBSS
Quality of service basic service set.
QSTA
QoS station.
STA (WSTA)
A non-AP IEEE 802.11 wireless station."

DESCRIPTION
"Changing the name of cid11QosDiscardedFragments
to cid11QosIfDiscardedFragments and description
to indicate it is for transmit fragments only.
Updating the description of cid11QosDiscardedFrames
to indicate it is for transmit frame only.

STATUS current
DESCRIPTION
"This is the 802.1D IP traffic category. There are
a total of 8 categories. Each category can be
mapped to a 802.1P priority level of IP packets.
The priority levels are implemented using the
Precedence Bits in the IP packets. The default
priority levels start from 'background', the
lowest, to the highest, 'networkControl':
background(1) - background traffic
(lowest priority)
spare(2) - spare traffic
(2nd lowest)
bestEffort(0) - best effort delivery
(this is the default
type for all traffic)
excellentEffort(3) - execellent effect
controlledLoad(4) - controlled load
interactiveVideo(5) - video traffic
interactiveVoice(6) - voice traffic
networkControl(7) - network control
packets (highest)."
