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.
