In a connection oriented LLC (Logical Link Control OS1 layer 2 data link layer) using a Selective Block Reject retransmission scheme, the peer notifies the sender not only if a datagram has been received but what portions have been received. It uses sequence numbers to distinguish one datagram from another. The acknowledgment information is critical in reducing needless re-trans- missions. The MAC (Media Access Control) layer is responsible for the actual addressing and selection of transmission path. With this invention the MAC will also send the LLC a Notification of end of transmission for each transmission received via the RF interface.
