  • Patent number: 12219357
    Abstract: Techniques and apparatus for managing a message relaying system are described. One technique includes an access point (AP) detecting a first signal and a second signal from a computing device. A validation of the first signal is performed based on parameters of the first signal and the second signal. After the validation, information associated with the first signal is transmitted to a computing system. In another technique, the computing system may designate one of multiple APs reporting information regarding first signals as a primary reporting AP and designate the remaining APs as secondary reporting APs. The computing system may instruct the secondary reporting APs to refrain from reporting information regarding first signals to the computing system.

  • Patent number: 12219583
    Abstract: Techniques to adaptively support/enable a wireless network feature for certain wireless client devices without hampering the performance or connectivity of wireless client devices which do not support that wireless network feature. An access point or wireless network controller adaptively enables a wireless network feature without advertising support for the wireless network feature in a wireless network-standard compliant manner to allow one or more wireless clients that support the wireless network feature to use the wireless network feature when associated to the access point while enabling association of one or more wireless clients that do not support the wireless network feature.

  • Publication number: 20250039043
    Abstract: A method of provisioning a network may include, with a network controller, identifying a first network intent of a computing network based at least in part on an execution of a user interface (UI) or API layer at a client device, and identifying a modification of at least one object within the first network intent within the UI or API layer at the client device as the first network intent is being modified. The modification defines a delta between the first network intent and a second network intent. The method may further include, with a provisioning service executed by the network controller, receiving the delta as a payload from the client device, and provisioning at least one computing device within the computing network based at least in part on the delta. The method further includes automatically modifying the at least one object based on the received delta, including a further modification of the second network intent.

  • Patent number: 12212451
    Abstract: In one embodiment, an issue analysis service obtains telemetry data from a plurality of devices in a network across a plurality of time intervals. The service detects a failure event in which a device in the network is in a failure state. The service clusters the telemetry data obtained prior to the failure event into rounds according to time intervals in which the telemetry data was collected. Each round corresponds to a particular time interval. The service applies a machine learning-based classifier to each one of the rounds of clustered telemetry data to identify one or more common traits appearing in the telemetry data for each round. The service generates a trait change report indicating a change in the one or more common traits appearing in the telemetry data across the rounds leading up to the failure event.

  • Patent number: 12209596
    Abstract: Various devices, systems, and methods are described herein that provide bi-directional, and even multi-directional airflow within fan systems. These fan systems can be utilized by devices such as datacenter switches to change from one direction of airflow (such as port side inlet) to another direction (such as port side exhaust). This can be done manually by having a multi-directional fan housed within an enclosure that provides access through a hatch door. The multi-directional fan can be removed and reoriented to a second direction, thus providing airflow with the same quality and pressure in multiple directions. Fan changes can also be automated through one or more interlocking rotational gears coupled to the fans within a housing, such that rotating one gear will rotate each of the fans within the housing, thus changing the direction of the airflow. By doing this, only one fan is needed to provide airflow in multiple directions.

  • Patent number: 12213095
    Abstract: A mobile network is operative to perform a quota validation procedure in relation to a maximum number of user equipments (UEs) permitted in a network slice. In one illustrative example, a control plane (CP) function of the mobile network may receive, from the UE, a message which indicates a registration request for registration and includes a slice ID of the network slice. The CP function may manage a registration procedure for assigning resources of the network slice to the UE. The CP function may alternatively manage the registration procedure to refrain from assigning the resources of the network slice to the UE, at least for a delay time period, based on identifying that an indication of the UE indicates an expected delay in use of service in the network slice. The indication may be included in the message and indicate the delay time period of the expected delay.

  • Patent number: 12212544
    Abstract: Techniques and architecture are described for providing a service, e.g., a security service such as a firewall, across different virtual networks/VRFs/VPN IDs. The techniques and architecture provide modifications in enterprise computing fabrics by modifying pull-based overlay protocols such as, for example, locator/identifier separation protocol (LISP), border gateway protocol ethernet virtual private network (BGP EVPN), etc. A map request carries additional information to instruct a map-server that even though mapping (destination prefix and firewall service RLOC for the destination) is known within the map-server's own virtual network/VRF for firewall service insertion, the map-server still should do a lookup across virtual networks/VRFs and discover the final destination's DGT (destination group tag) and include that in the map reply.
