Study on the Throughput Limits over the HDLC Protocol Study on the Throughput Limits over the HDLC Protocol

This paper describes the throughput evaluation of the high level data link control protocol. The analytical models are outlined and the throughput analysis is carried out under fully loaded condition for the following three error recovery schemes: (1)Checkpoint retransmission scheme, (2)SREJ recovery scheme and (3)REJ recovery scheme. We derive the optimal packet text length which achieves the maximum throughput for each error recovery scheme. Also we denote the optimal window size for the checkpoint retransmission scheme.
