  • Publication number: 20240284170
    Abstract: Implementations of the present disclosure relate to detection of an untrusted configurator. In the implementations, an access point (AP) receives enrollee authentication information simulated by the network device from a network device. Then, the AP simulates an enrollee and broadcasts a configuration request including the enrollee authentication information. When a configurator responds to the configuration request, the AP identifies the configurator as an untrusted configurator, and then the AP transmits device information of the untrusted configurator to the network device. In this way, the untrusted configurator in the serving range can be detected, thereby avoiding the devices being provisioned to connect to untrusted networks.

  • Publication number: 20230403235
    Abstract: Load aware load balancing may be provided. Flow duration data associated with a plurality of flows associated with a plurality of servers may be obtained. Then a plurality of queue lengths respectively associated with the plurality of servers may be obtained. Next, a Shortest Expected Delay (SED) score may be determined for each of the plurality of servers based on the flow duration data and the plurality of queue lengths. A flow may then be assigned to a one of the plurality of servers having the lowest SED score.

  • Patent number: 10849087
    Abstract: Systems and methods are provided for implementing a coexistence coordinator in an access point (AP) operating in a Internet of Things (IoT) network. The coexistence coordinator coordinates transmission of both IoT-related data from an IoT radio and WiFi data from a WiFi radio, the IoT radio and the WiFi radio coexisting in the AP. The coexistence coordinator synchronizes time between the WiFi radio and the IoT radio so that times during which IoT-related data is to be sent from the IoT radio (in accordance with Time-Division Multiple Access (TDMA) channel access method) can be determined. Operation of the WiFi radio is suspended during those times when the IoT-related data is transmitted from the IoT radio.
