    Abstract: This disclosure describes techniques for device to device authentication. For instance, a first device may detect a second device, such as when a user physically attaches the second device to the first device or when the second device wireless communicates with the first device. A component of the first device and/or an authentication entity may then determine to authenticate the second device. In some instances, the component determines to authenticate the second device using information associated with an environment of the second device. To authenticate the second device, the authentication entity may send a request to a user, receive a response from the user, and then verify the response. After the authentication, the first device may determine that the second device includes a trusted device and establish a connection with the second device.

    Abstract: In one embodiment, techniques for adaptive forward error correction (FEC) in LPWANS are disclosed. The techniques may include determining, by a process, for a block of messages transmitted through a computer network with forward error correction, whether any unrecovered data loss occurred during transmission; increasing, by the process, a level of forward error correction used to transmit through the computer network in response to unrecovered data loss; and/or decreasing, by the process, the level of forward error correction used to transmit through the computer network in response to no unrecovered data loss.

    Abstract: Predicting network throughput and balancing network loads may be provided. Predicting network throughput and balancing network loads can comprise receiving traffic information from a plurality of Access Points (APs). Based on the traffic information, traffic associated with the plurality of APs can be modeled. Based on the modeled traffic, a gain in AP efficiency for one or more APs of the plurality of APs can be modeled when modifying Station (STA) traffic of a STA. A recommendation can be sent to one or more recipient APs of the plurality of APs, wherein the recommendation indicates the gain in AP efficiency for the one or more APs when modifying the STA traffic.

    Abstract: Techniques for improving telemetry in resource-constrained device environments. In some examples, the techniques include gossiping telemetry information between peer devices of a wireless network to, among other things, reduce telemetry cost and/or an amount of telemetry data streamed to a telemetry collector. In some examples, the techniques may also include intelligently exporting telemetry data from resource-constrained devices towards backend systems without exhausting the resource-constrained devices and/or the backend systems. In examples, the telemetry data may be contextual information associated with an endpoint, an application, a network-device resource (e.g., CPU, battery, memory, storage, etc.), geographical constraints, and/or the like.

    Abstract: Devices, systems, methods, and processes for network device power management at the floor level are described herein. Network devices can communicate with various devices in a wireless network. However, environmental changes, barriers, and other hazards exist in each deployment environment. To better understand each deployment environment, a floorplan can be generated by sending out a plurality of test frames. These test frames can be formatted with power data that is associated with the transmission power level that each test frame is transmitted at. The receiving network device can compare this power data with an actual measurement of the received signals. This data can all be packaged into a client report that can be sent back to the transmitting device which can then process this client report from multiple network devices such that a floorplan can be generated which can be utilized to make more efficient network decisions in the future.

    Abstract: Techniques for identifying nodes in a data center fabric that are affected by a failure in the fabric, and selectively sending disaggregation advertisements to the nodes affected by the failure. The techniques include a process where a component monitors the network fabric to identify communication paths between leaf nodes, and determines what leaf nodes would be affected by a failure in those communication paths. The component may detect a failure in the network and determine which communication paths, and thus which leaf nodes, are affected by the failure and send disaggregation advertisements to the affected leaf nodes. In some examples, ingress leaf nodes send data through the fabric that indicate egress nodes for the communication paths. Intermediate nodes along may receive the data from the leaf nodes to identify communication paths, and the notify only affected nodes upon detecting a failure in the network.
