Summary:Simulcast flow-controlled data streams is described. In embodiment(s), multicast data streams each communicate data to client devices at a different data rate. A high data rate of a first data stream can be reduced to accommodate a receive data rate of a client device that receives the data slower than the high data rate of the first data stream. A flow control service can monitor the high data rate of the first data stream to determine when the high data rate is reduced to a low trigger data rate, initiate a data stream probe at a probe data rate to determine slow client devices that receive the data slower than the probe data rate, and then demote the slow client devices for communication with a second data stream that communicates the data at a low data rate.
