Abstract: Techniques for traffic steering are disclosed. A first signal characteristic of a first connection between an electronic device and a first wireless communications network is determined. A second signal characteristic of a second connection between the electronic device and a second wireless communications network is also determined. Based on the first signal characteristic and the second signal characteristic, the electronic device is prevented from attempting to establish the second connection until one or more establishment criteria are met.

Abstract: Adaptive guard interval calibration may be provided. A computing device may receive a first plurality of delay spread values. Each of the first plurality of delay spread values may respectively comprise an amount of time between when each of a respective first plurality Access Points (APs) receives a first tuning symbol from a first calibrating AP and when each of the respective first plurality APs receives a final multipath reflection of the first tuning symbol. Next, a first Guard Interval (GI) may be determined based on the first plurality of delay spread values. The first calibrating AP may then be provisioned with the first GI.

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: Load balancing for saturated wireless may be provided. A computing device may determine that an Access Point (AP) has reached a saturation point. A first Service Device (SD) having a first SD coverage area that overlaps an AP coverage area associated with the AP may be identified. Then a license to operate within a frequency spectrum segment for the first SD coverage area may be obtained. A plurality of user devices may be moved from the AP to the first SD. The first SD may then service the plurality of user devices using at least a portion of the frequency spectrum segment.

Abstract: Systems, methods, and computer-readable media for the secure creation of application containers for 5G slices. A MEC application in a MEC layer of a 5G network can be associated with a specific network slice of the 5G network. A backhaul routing policy for the MEC application can be defined based on the association of the MEC application with the specific network slice of the 5G network. Further, a SID for the MEC application that associates the MEC application with a segment routing tunnel through a backhaul of the 5G network can be generated. A MEC layer access policy for the MEC application can be defined based on the SID for the MEC application. As follows, access to the MEC application through the 5G network can be controlled based on both the backhaul routing policy for the MEC application and the MEC layer access policy for the application.

Abstract: This disclosure describes techniques for improving allocation of computing resources to computation of machine learning tasks, including on massive computing systems hosting machine learning models. A method includes a computing system, based on a computational metric trend and/or a predicted computational metric of a past task model, allocating a computing resource for computing of a machine learning task by a current task model prior to runtime of the current task model; computing the machine learning task by executing a copy of the current task model; quantifying a computational metric of the copy of the current task model; determining a computational metric trend based on the computational metric; deriving a predicted computational metric of the copy of the current task model based on the computational metric; and, based on the computational metric trend, changing allocation of a computing resource for computing of the machine learning task by the current task model.

Abstract: Automated activation of unsolicited probe responses may be provided. Probe traffic data may be received. Then, based on the probe traffic data, a plurality of probe traffic cost metrics may be determined. Each one of the plurality of probe traffic cost metrics may be respectively associated with a plurality of Unsolicited Probe Response (UPR) modes. An Access Point (AP) may then be operated in a one of the plurality of UPR modes that has a respective probe traffic cost metric that indicates a lowest probe traffic cost of the plurality of probe traffic cost metrics.

Abstract: A network controller provides proactive notification of a wireless client device's address rotation to layer 2 (L2) and/or layer 3 (L3) devices. Traditional methods of device address discovery rely on broadcasting of address queries across a plurality of links until a path to a device having the queried address responds. As device address changes become more frequent in an effort to improve user privacy, traditional methods of address discovery impose a large burden on networks, reducing their performance and efficiency. By proactively propagating address changes to upstream devices, the need for broadcast oriented address discovery techniques is reduced, resulting in improved network performance.

Abstract: A method includes detecting, by a mobile device, a light sequence emitted from a plurality of light emitting diodes on an access point and determining, by the mobile device, an identifier for the access point based on the light sequence. The method also includes reporting, by the mobile device, a geospatial location of the mobile device and the identifier for the access point to an automated frequency coordination (AFC) server to perform AFC for the access point.

Abstract: Rotation of a wireless client device address is based on an encryption key and a nonce value. Key information and nonce value information are shared between a wireless client device and a network infrastructure component over a secure communication channel. The wireless client device encrypts the nonce value using the key information and encodes the encrypted value as a device address. The wireless client device then identifies itself via a source address value in a message transmitted over a wireless network. Upon receiving the message, the network infrastructure component decrypts information derived from the source address value and compares the resulting data to the nonce value. If a match is identified, the network infrastructure identifies the wireless client device as a source of the message. In some embodiments, the nonce value is updated with each rotation to provide for improved entropy of generated device addresses.
