  • Patent number: 11005901
    Abstract: One or more data centers are selected to host an online conference. The selection of the data center is based on a set of metrics that are measured from ‘synthetic’ transactions. These synthetic transactions are sent between candidate data centers and the participants in the conference call in order to measure one or more performance metrics (e.g., link quality metrics such as delay, packet loss, etc.) These measured performance metrics are used to determine a centroid that represents the geometric center or ‘center of mass,’ of the link quality between participants and data centers. This ‘link quality centroid’ is used to select a subset of data centers as candidate data centers. The candidate data center with the best average performance metric(s) is selected as the data center to host the conference.

  • Patent number: 10939310
    Abstract: Methods and apparatus in a wireless network that allow devices, such as client devices and access points (APs), having software defined radios (SDRs) to change operating behavior depending on network RF environment conditions are disclosed. The devices may be instructed to operate according to differently defined behavior profiles that may be chosen based on RF environment conditions. The profiles may be stored in a database. A particular profile may be obtained from the database for one or more devices based on an interference level within an RF environment of the devices. The profiles may be implemented to change device operating behavior so that interference is reduced or minimized in higher levels of interference. The profiles may also be implemented to change device behavior so that interference is reduced in lower levels of interference while also freeing up resources for more efficient use in the network during lower levels of interference.

  • Patent number: 10860840
    Abstract: A computing device stores an acquired image as a transient image template when there is a failure in an image-based authentication of the acquired image and the user of the computing device has provided user credentials that authorize the user to access the computing device. The transient image template may be used to further authorize the user to access the computing device during a predetermined time period. At the expiration of the predetermined time period, the computing device deletes the transient image template. The computing device then reverts to using a baseline image template for performing image-based authentication of the user. The transient image template may also be associated with a location such that the computing device uses the transient image template for image-based authentication when the computing device is at or near the location.

  • Patent number: 10778728
    Abstract: The patterns of usage, participation, and/or item sharing by the participants in a conference call are correlated, recognized, and used to select a data centers. This selection can be done both before and/or during a call. When significant patterns are recognized (e.g., heavy video sharing by one participant at every Friday afternoon meeting) there may be a better (e.g., faster, better quality, more efficient, less use of network resources) data center to host the call than one that is selected based on the geography of the participants alone. Likewise, during a call, other patterns of behavior can be correlated and recognized dynamically such that when these patterns occur, the call is hosted by a different (i.e., better) data center.
