摘要： Multimodal wireless and deterministic mode operation may be provided. An indication may be provided to a client device by an Access Point (AP) that the AP supports multimode operation and which current sub-mode is enabled. Then a determination may be received from the client device to perform an operation based on the indication that the AP supports multimode operation and which sub-mode is currently enabled wherein the operation comprises one of prefer the AP and avoid the AP.

摘要： Leveraging wireless direct transmissions may be provided. It may be determined that data traffic flowing on a first pathway between a first client device and a second client device is not meeting a predetermined service level. The first pathway may be partially wired and partially wireless. A second pathway that will meet the predetermined service level may be determined. The second pathway may be wireless. The data traffic may be caused to flow on the second pathway.

摘要： Techniques for adjusting a duration of an authenticated user device session. A baseline session duration is determined for a session for which a user account is authorized in response to a request for authentication. A first session is established on behalf of a user device associated with the user account based at least in part on the user account performing a first authentication. A posture associated with the user device is determined. The baseline duration is then adjusted to a dynamic duration based at least in part upon the posture associated with the user device. Based at least in part on the dynamic duration the user can be required to re-authenticate.

摘要： In one embodiment, a method comprises causing, by a network controller device, a first access point (AP) device to initiate a reverse sounding operation comprising wireles sly requesting a mobile constrained network device to transmit a null data packet (NDP) at a first transmission interval, wirelessly receiving the NDP at the first transmission interval, and generating a reception report describing reception of the NDP and including beamforming information; causing, by the network controller device, a second AP device to generate a corresponding reception report describing a corresponding wireless detection of the NDP at the first transmission interval; and causing, by the network controller device, the mobile constrained network device to connect to a selected one of the first AP device or the second AP device for an identified data flow based on the respective reception reports from the first and second AP devices.

摘要： In one embodiment, a service receives a feature availability report indicative of which telemetry variables are available at a device in a network and resource costs associated with data features that the device could compute from the telemetry variables. The service selects at least a subset of the data features for input to a machine learning model, based on their associated resource costs and on their respective impacts on one or more performance metrics for the machine learning model. The service trains the machine learning model to evaluate the selected data features. The service sends the trained machine learning model to the device. The device computes the selected data features from the telemetry variables available at the device and uses the computed data features as input to the machine learning model.

摘要： Systems and methods may include sending, to a network registrar, a first message including a first nonce generated by a host computing device, and receiving, from the network registrar, a second message including a second nonce, the second nonce being signed by the network registrar via a private key of a first public key infrastructure (PKI) key pair of the network registrar via a first signature. The method further includes sending a first neighbor advertisement (NA) message to the host computing device including the second nonce. The second nonce and the private key of the network registrar verifies the first signature from the network registrar, the verification of the first signature indicating that the router is not impersonating the network.

摘要： In one embodiment, a method comprises identifying a fat tree network topology comprising top-of-fabric (ToF) switching devices, an intermediate layer of intermediate switching devices connected to each of the ToF switching devices, and a layer of leaf network devices; and causing a first leaf network device to initiate establishment of first and second redundant multicast trees for multicasting of data packets, including: causing first and second ToF switching devices to operate as roots of the first and second multicast trees according to first and second attribute types, respectively, causing the first leaf network device to select first and second of the intermediate switching devices as first and second flooding relays belonging to the first and second attribute types, respectively, and causing the first and second flooding relays to limit propagation of registration messages generated by the first leaf network device to the first and second ToF switching devices, respectively.

摘要： This disclosure describes techniques for authenticating a user device for a session. For instance, an authentication entity may authenticate a user device using single sign-on authentication and/or multi-factor authentication. The authentication entity may then determine a duration for which the user device is authenticated for the session. For example, the authentication entity may receive information representing a state of an environment of the user device. The authentication entity may then use the information to identify one or more transitions associated with the environment between the session and a previous session. Using the one or more transitions, the authentication entity may determine the duration for the session by increasing or decreasing a previous duration associated with the previous session.

摘要： In one embodiment, a method comprises: receiving, by a constrained wireless network device comprising a local clock, a plurality of messages from respective neighboring wireless network devices advertising as available parent devices in a directed acyclic graph of a time-synchronized network that is synchronized to a master clock device; determining, by the constrained wireless network device, a corresponding timing error of the local clock relative to each message output by the corresponding available parent device; and executing, by the constrained wireless network device, a distributed time synchronization of the local clock with the master clock device based on correlating the respective timing errors relative to the local clock.
