In the method and apparatus for transmitting data packets, a source device places identifiers in data packets being transmitted. The identifiers identify data packets that the source device considers properly received by a destination device or identify data packets that have had their transmission aborted by the source device. When the destination device receives data packets including these identifiers and the identifiers identify data packets that the destination device has yet to receive, the destination device will proceed as if the identified data packets have been re-sequenced.
