A methodfor minimizing propagation timeof at least one queued-up datalinkTPDU comprises determining whether a current TPDU ready for transmission requires acknowledgement; transmitting the current TPDU, starting a retry timer, and setting a transmission count to one, when acknowledgement required; determining whether acknowledgement received after transmitting the current TPDU; determining whether a pending TPDUis awaiting transmission when acknowledgement is not received; when a pending TPDU is awaiting transmission, determining whether elapsed wait time of the currentTPDU is greater than a preselected minimum; incrementing the transmission count by one when elapsed wait time is greater than the preselected minimum; determining again whether there is a pending TPDUawaiting transmission when the transmission count is less than a predetermined maximum and an inactivity timer has not expired; and when there is still at least one pending TPDU awaiting transmission, retransmitting the current TPDU and restarting the retry timer. |
