Abstract: Aspects of the disclosure relate to multicasting content throughout a distribution network. For example, a content server may generate content fragment packets and attribute packets, and transmit the content fragment packets and attribute packets via a multicast transmission to deliver content to one or more user devices. The multicast transmission may conform to a particular protocol suitable for multicasting content fragments.

Abstract: Aspects of the disclosure relate to monitoring and using telemetry information in various ways. For example, a system that monitors telemetry information may include a user that gathers telemetry information of a device and transmits the information to a monitored room. A manager may join a monitored room and monitor the monitored room for particular types of telemetry information. In one example, a manager may determine whether a downstream device is experiencing a network problem, such as a low bitrate. A manager may also transmit commands to the player via the monitored room, which causes the downstream device to operate in accordance with the transmitted command. In one example, a manager may transmit a command that causes a player to decode a particular service.
