ABSTRACT:
A device and method for controlling data unit communications between a sender and a receiver, and flexibly responding to a potential data loss event. Data units are transmitted from the sender to the receiver, and the receiver returns an acknowledgment data unit for each data unit received. If the receiver fails to receive a data unit, the sender retransmits the data unit in accordance with a data unit loss response procedure. If the potentially lost data unit is subsequently received, the sender determines whether the correctly received data unit was the initial data unit or the retransmission. If the correctly received data unit was the retransmission, the sender continues to transmit subsequent data units in accordance with the data unit loss response procedure. However, if the correctly received data unit was the initial data unit, the sender transmits subsequent data units in accordance with an excessive delay response procedure.
