  • Publication number: 20230354086
    Abstract: An access point device can utilize a deep packet inspection (DPI) management device for inspecting traffic associated with a session of a station for quality of service (QoS) information. The QoS information is compared to DPI application and device categories. Based on the comparison a Wi-Fi QoS Management controller of the access point device can determine a QoS policy for the session based on the comparison. The access point device can send a request to the station to assign a QoS priority to the session based on the QoS policy. The request can apply to upstream traffic, downstream traffic, or both. The QoS policy provide a priority level for the session so that the associated traffic receives a QoS appropriate or required by the associated application, device, or both so as to provide Wi-Fi QoS Management for traffic associated with the station.
