Abstract: Systems and methods are provided for synchronizing uplink (UL) and downlink (DL) traffic. In particular, frames associated with Quality of Service (QoS}-sensitive traffic flows to be transmitted in a first direction are prioritized commensurate with frames to be transmitted in a second direction, different/opposite to that of the first direction. For example, UL traffic flows can be prioritized based on DL traffic flows, where the traffic flows belong to the same application flow, and vice versa, where DL traffic flows can be prioritized based on UL traffic flows for the same application flow. In this way, end-to-end QoS can be achieved.

Abstract: Examples relate to configuring dynamic user roles that can be managed and distributed by a cloud-based user role service. In this way, dynamic user roles may be distributed in a more scalable manner than has been previously possible. Upon associating or connecting to an access point (AP), for example, a user device can be authenticated and assigned a user role. The AP can request the user role configuration from the cloud-based user role service. The cloud-based user role service can additionally distribute the same user role configuration/details to all neighboring APs. In this way, a user device can move, roam, or otherwise associate to another AP that post-distribution, already has the (dynamic) user role configuration, which can simply be applied to the user device.
