Integration

4.5.2.2 Integration

If the distribution service determines that the intended recipient of a message is a member of an integrated
LAN, the “output” point of the DS would be a portal instead of an AP.
Messages that are distributed to a portal cause the DS to invoke the Integration function (conceptually after
the distribution service). The Integration function is responsible for accomplishing whatever is needed to
deliver a message from the DSM to the integrated LAN media (including any required media or address
space translations). Integration is one of the services in the DSS.
Messages received from an integrated LAN (via a portal) by the DS for an IEEE 802.11 STA invoke the
Integration function before the message is distributed by the distribution service.
The details of an Integration function are dependent on a specific DS implementation and are outside the
scope of this standard.

4.5.2.3 QoS traffic scheduling
QoS traffic scheduling provides intra-BSS QoS frame transfers under the HCF, using either contentionbased
or controlled channel access. At each TXOP, a traffic scheduling entity at the STA selects a frame for
transmission, from the set of frames at the heads of a plurality of traffic queues, based on requested UP and/
or parameter values in the traffic specification (TSPEC) for the requested MSDU. Additional information is
available in 9.19.
4.5.3 Services that support the distribution service
4.5.3.1 General
The primary purpose of a MAC sublayer is to transfer MSDUs between MAC sublayer entities. The
information required for the distribution service to operate is provided by the association services. Before a
data message can be handled by the distribution service, a STA is “associated.”
To understand the concept of association, it is necessary first to understand the concept of mobility.
