Abstract: The present invention concerns a method and a device for transmitting data between a sender, and at least two receivers, in a network where a data between a sender and a receiver is carried on a connection and where a unicast connection enables a sender to send the data and a receiver to acknowledge a reception of the data. The method comprises the steps of opening a unique unicast connection identified with a connection identifier; and indicating the connection identifier to the sender and the receivers, so that the sender sends the data on the unicast connection, and the receivers receive the data on the unicast connection.
