A method and system for facilitating one-to-many data transmissions with reduced network overhead includes conducting a round of data transmissions from a source computing device to a plurality of sink computing devices. Each of the sink computing devices generates a bucket list of lost data blocks for the round of data transmissions and transmits the bucket list to the source computing device. The source computing device conducts a subsequent round of data transmissions based on the bucket lists. One or more additional subsequent rounds may be conducted until the bucket list of each sink computing device is empty.
