DEFINITIONS - 10

mesh peer service period (MPSP) owner: A mesh station (STA) that obtains transmission opportunities
(TXOPs), transmits individually addressed frames to the recipient mesh STA in the mesh peer service
period, and terminates the mesh peer service period.
mesh peering: A relationship between two mesh stations (STAs) that is required for direct communication
over a single instance of the wireless medium (WM). A mesh peering is established with a mesh peering
protocol.
mesh peering management: A group of protocols to facilitate the mesh peering establishment and closure
of the mesh peerings.
mesh power mode: The activity level identifier of a mesh station (STA) set per mesh peering or for nonpeer
neighbor STAs. A lower activity level enables a mesh STA to reduce its power consumption.
mesh power mode tracking: Operation to observe the peering-specific mesh power modes from the peer
mesh STAs and to maintain the peering-specific mesh power modes for each peer mesh STA.
mesh profile: A set of values of parameters that identifies the attributes of the mesh basic service set
(MBSS) and that is used in a single mesh BSS. The mesh profile consists of the identifiers that are the values
for the parameters: mesh ID, active path selection protocol, active path selection metric, congestion control
mode, synchronization method, and authentication protocol.
mesh services: The set of services that enable the creation and operation of a mesh basic service set
(MBSS).
mesh station (STA): A quality-of-service (QoS) STA that implements the mesh facility.
message integrity code (MIC): A value generated by a cryptographic function. If the input data are
changed, a new value cannot be correctly computed without knowledge of the cryptographic key(s) used by
the cryptographic function.
NOTE—This is traditionally called a message authentication code (MAC), but the acronym MAC is already reserved
for another meaning in this standard.
mobile station (STA): A type of STA that uses network communications while in motion.
mobility domain: A set of basic service sets (BSSs), within the same extended service set (ESS), that
support fast BSS transitions between themselves and that are identified by the set’s mobility domain
identifier (MDID).
mobility domain identifier (MDID): An identifier that names a mobility domain.
multi-level precedence and preemption (MLPP): A framework used with admission control for the
treatment of traffic streams based on precedence, which supports the preemption of an active traffic stream
by a higher precedence traffic stream when resources are limited. Preemption is the act of forcibly removing
a traffic stream in progress in order to free up resources for another higher precedence traffic stream.
multicast: See: group addressed.
multicast address: See: group address.
