A data transfer system and method are described for providing transfer of data over a network between a sender and a plurality of receivers. Data is sent over a network to the plurality of receivers by the sender at a specified rate regardless of data loss. A receiver that identifies a lost block of data transmits a retransmission request to the sender. The sender responds to one or more retransmission requests by transmitting a repair packet to all receivers that contains blocks of data for which retransmission requests have been received.
