Load Balancing Patents (Class 455/453)
  • Patent number: 11368337
    Abstract: Systems and methods are disclosed for using one or more gateway systems for integrating multiple load control systems running multiple versions of software such that the load control systems may appear to a user and be controlled by the user as a unified load control system. Gateways that manage or have managed the same resource may be organized into a Gateway Group. Gateway Groups names may be used for prefix attachment to facilitate routing. For example, a Composite Gateway may receive a request associated with a resource from a user. The Composite Gateway may determine which Gateway actively manages that resource and/or is the Gateway is a member of a Gateway Group. The composite Gateway may then apply one or more policies to facilitate the request. For example, if the Composite Gateway receives an information request, it may apply an authorization policy, a routing policy, and/or an aggregation policy.

  • Patent number: 11356349
    Abstract: Communications services are provided to a device. For instance, where a communications resource is being used by a device via a first communications service provider (CSP) component associated with a first CSP, based on a probabilistic analysis of loading parameters received from a device at the first CSP component. A likelihood that the device will move can be predicted, comprising determining the likelihood is not less than a threshold likelihood. If likely to move, and based on the loading parameters, a loading profile associated with a user of the device is updated resulting in updated likelihoods of usages of the communication resource by the device via respective other CSP components other than the first CSP component. Further, based on the updated likelihoods of usages of the communication resource, at least part of the communications resource can be allocated to the respective other CSP components to facilitate communications with the device.

  • Patent number: 11310724
    Abstract: When an access point associates with an electronic device, the access point may establish secure communication with the electronic device using a four-way handshake with the electronic device. Next, the access point may distribute secondary pairwise master keys (PMKs) to radio-frequency (RF)-neighbor access points of the access point in a wireless local area network, where the secondary PMKs facilitate fast basic service set (BSS) transitions with the electronic device when a handover occurs without using the four-way handshake to establish secure communication with the electronic device. Furthermore, when the access point receives information that indicates that the electronic device has associated with a second access point in the RF-neighbor access points of the access point, the access point provides instructions to delete the secondary PMKs at the RF-neighbor access points of the access point, and provides additional secondary PMKs to RF-neighbor access points of the second access point.

  • Patent number: 10939468
    Abstract: A radio receiver is arranged to receive radio signals. The radio receiver includes a tuner, which outputs an electronic signal representing radio waves received by the radio receiver; a correlator, which cross-correlates a predetermined signal pattern with the electronic signal, and outputs a correlation signal; and a clear channel assessment module. The clear channel assessment module determines when the number of peaks in the correlation signal, over a fixed time window, exceeds a threshold count value, and outputs a busy signal in response to determining that the number of peaks exceeds the threshold count value.

  • Patent number: 10936078
    Abstract: A configurable load balancer can be utilized in a multi-tenant environment, where the load balancer can incorporate, or utilize, an account management service operable to perform security tasks such as authentication, authorization, and session management. Customers can utilize the load balancer to control access that users have to resources associated with those customers, without having to build and maintain a dedicated user management system. By implementing security functionality at the load balancer level, traffic can be managed before reaching the resources, which can help to reduce traffic and load on the resources, and can also help to prevent attacks and secure sensitive information. Visibility into the traffic through the load balancer also allows for behavior and usage monitoring, which is helpful for tasks such as billing and usage limit enforcement.

  • Patent number: 10887200
    Abstract: Methods, systems, and computer readable media may be operable to facilitate client device band steering based upon deep packet inspection information. An access point may be configured to steer one or more client devices from a low frequency band to a high frequency band, and vice versa, based on the status of the low frequency band and/or high frequency band and the client devices associated with the bands. The access point may perform a deep packet inspection of data packet traffic associated with each associated client device, and may classify each client device as either a device associated with a media session or a device that is not associated with a media session based upon information retrieved from the deep packet inspection. The access point may choose one or more client devices to disassociate from a frequency band based upon the media session classification of the client devices.

A global resource coordinator in the communication network allocates first radio resources to a first local resource coordinator in a first cell of the communication network. The first radio resources are used by at least one non-stationary radio device in the first cell, making some of the first radio resources allocated to a non-stationary radio device in the first cell exclusively available for the non-stationary radio device in one or more second cells next to the first cell. The global resource coordinator divides radio resources allocated to the non-stationary radio device in time slots in the time domain in a disjunctive manner into a first portion for the non-stationary radio device and a second portion.

  • Patent number: 10820244
    Abstract: Traffic associated with user equipment that are coupled to a first radio access network is steered to a second radio access network based on an adaptable signal strength criterion. The signal strength criterion is related to real-time network load conditions of the first radio access network and can be broadcasted from a serving access point to the user equipment. Moreover, the signal strength criterion facilitates steering, to the second radio network, traffic associated with user equipment that are located closer to a cell edge of the first radio access network before steering traffic associated with user equipment are located further away from the cell edge. In addition, based on the network congestion within the first radio access network, the signal strength criterion is modified to adjust the number of user equipment that are steered to the second radio network.
