Data is transmitted over a computer network from a source network component to one or more destination network components. Thereafter, one or more acknowledgements are transmitted from one of the destination network components to the source network component; and different data, which may include retransmissions, from the previously transmitted data is transmitted from the source network component to the one or more destination network components. A negative acknowledgement message from the destination network component may be transmitted to the source network component upon a failure to receive one or more of the transmitted data packets, the negative acknowledgment including packet identifications of said one or more data packets. Then data packets identified by the identifications received in a negative acknowledgement may be retransmitted before transmitting other packets. The negative acknowledgements thus indicate failed receipt of data. Positive acknowledgements indicate successful receipt of data.
