  • Allocating requests
    Patent number: 11574044
    Abstract: This disclosure describes, in part, techniques and systems for enabling new devices introduced into respective environments (“provisionee devices”) to be provisioned by existing devices in the respective environments (“provisioner devices”) in a manner in which the provisioning requests sent by the provisioner devices are allocated over time and, thus, do not overwhelm the provisioning system(s) at any given time.

  • Efficient buffer allocation for current and predicted active speakers in voice conferencing systems
    Patent number: 7046780
    Abstract: A method and computer program product allows for the efficient allocation of buffers (e.g., first-in first-out (FIFO) queues) for current and predicted active speakers in voice conferencing systems. The method and computer program product, implemented by a server hosting an audio conference for a plurality of speakers, minimizes the loss of audio data for speakers as they switch from “non-active” to “active” status. This is accomplished by employing a set of active speaker buffers and a set of predicted active speaker buffers. The predicted active speaker buffers maintain a collection of the most recent x packets or m milliseconds of “non-active” speaker audio data, and transfer a portion of the data from the predicted active speaker buffers to the active speaker buffers as speakers become “active” speakers.
