Abstract: In one embodiment, an IoT server includes: processing circuitry, an I/O module operative to communicate with at least an IoT device and a vendor network server, and an onboarding application and operative to at least: receive an onboarding request from the IoT device via the I/O module, send a confirmation request to the vendor network server via the I/O module, where the confirmation request indicates a request to confirm an identity of the IoT device according to a connection to a network device authenticated by the vendor network server, receive a confirmation response from the vendor network server via the I/O module, where the confirmation response indicates whether the IoT device is connected to the network device, and if the confirmation response is a positive confirmation response that indicates that the IoT device is connected to the network device, onboard the IoT device for participation in an IoT-based system.

Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

Abstract: Secure network segmentation using logical subnet segments is described. A single network segment or subnet provided by a third party is mapped into multiple layer-3 virtual or logical segments without requiring separate subnets. This mapping is accomplished by using virtual routing functions (VRFs) per logical subnet segment while retaining a single subnet across the segments. The logical subnet segments interact with the single network segment provided by the third party (ISP). The layer-3 VRF instances are created without the need for separate IP subnet pools per layer-3 segment. Each VRF instance for the various logical subnet segments is mapped to an identifier and tag.
