    Abstract: Embodiments herein describe techniques for dynamically negotiating an SLA between a roaming device and a VN in an identity federation. Instead of an IDP having to individually negotiate with a VN to decide on an SLA before a user device roams to the VN, the parties can dynamically negotiate the SLA after the user device has detected the VN (but before the device is permitted to connect or associate with the VN). In one embodiment, when a roaming user device comes within wireless range of a VN, the roaming device receives an advertisement from the VN that indicates the current SLA (or SLAs) offered by the VN. The roaming device can compare this offered SLA to a stored SLA in an identity profile the device received from the IDP to determine whether to accept the offer. In another embodiment, the SLA is instead negotiated between VN and the IDP.

    Abstract: Dynamic policy mapping is provided via mapping, by an Access Point (AP), a plurality of applications to a set of privilege groups for Quality of Service (QoS) levels in a network; transmitting the mapping of the privilege groups to a client device; receiving packets from the client device including QoS markers; and in response to determining that the QoS markers received from the client device do not match the privilege groups for the packets, performing a corrective action on the client device, wherein the corrective action includes one or more of: disassociating the client device from the network; and retransmitting the set of privilege groups to the client device. In some embodiments, the privilege groups are transmitted before the client device is associated with the AP, enabling the client device to select what AP to associate with based on the privilege groups.

    Abstract: Handoff assistance across multiple radio access technologies can be provided by identifying a first Qualitative Level of Service (QLoS) of a first network that a User Equipment (UE) is connected to for data transmission; identifying a second QLoS of a second network that the UE is not connected to for data transmission; and in response to determining that a difference between the first QLoS and the second QLoS satisfies a handoff threshold, requesting a first access point in the first network to initiate handoff of the UE to a second access point in the second network or recommending from the first access point to the UE to request such a handoff, wherein handoff disconnects the UE from the first network for data transmission and connects the UE to the second network for data transmission.

    Abstract: Techniques for uplink scheduling in a wireless network are disclosed. A wireless access point (AP) receives, from a wireless station (STA), a buffer status report (BSR) reflecting data accumulated at the STA for uplink to the AP. The AP identifies, based on the BSR, a scheduling mode under which the data was accumulated at the STA. The AP schedules an uplink parameter for the STA, based on the identified scheduling mode. The uplink parameter relates to at least one of: (i) an uplink transmission for the STA or (ii) a buffer status poll for the STA. The AP transmits, to the STA, an allocation relating to the scheduled uplink parameter for the STA.

    Abstract: Automating and extending path tracing through wireless links is provided by receiving request to perform a network trace over a wireless link provided by an Access Point (AP) configured as a transparent forwarder between a trace source and a trace target; monitoring a trace packet from a first time of arrival at the AP, a first time of departure from the AP, a second time of arrival at the AP, and a second time of departure from the AP; monitoring a buffer status of the AP at the first time of arrival and the second time of arrival; and in response to identifying a network anomaly based on the trace packet and the buffer status, adjusting a network setting at the AP.

    Abstract: Techniques for determining a range between a wireless station (STA) and a wireless access point (AP) using channel state information are described. An AP determines channel state information corresponding to an STA. The AP determines, based on the channel state information, one or more fine timing measurement (FTM) parameters. A plurality of FTM messages are transmitted between the AP and the STA, based on the one or more FTM parameters. The STA is configured to determine an estimated range to the AP based on the plurality of FTM messages.
