Selective packet retransmission with timing control at the transmitter end

摘要

The invention proposes a mechanism for retransmitting packets which comprises a step for checking at the transmitter whether the retransmitted packet will be received by the receiver in time to be processed. To this end, the receiver sends in its retransmission request the processing time indication of the packet being processed at the receiver when the request is transmitted. At the transmitter end, this processing time indication is compared with the processing time indication of the packet to be retransmitted so as to authorize or block its retransmission.
