Abstract: A transmission system that sends data to multiple devices simultaneously using multiple access points (APs). The system may send multicast data (e.g., original transmission of multicast data) to the multiple devices using a first AP and may send recovery data (e.g., retransmission of portions of the multicast data) to individual devices using a second AP. As the second AP handles requests for the recovery data and sends the recovery data, the first AP may send the multicast data using all available bandwidth and an efficiency of transmission does not depend on the number of devices connected to the first AP. The recovery data may be determined based on an original manifest of the multicast data, such as a bitmap or other representation, and the device may generate a recovery manifest indicating the recovery data and send the recovery manifest to the second AP.

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.
