Abstract ARQ (Automatic Repeat Request) schemes are methods for controlling the error in data transmission. Among the schemes previously proposed are the selective repeat, the GO‐BACK‐N, and the combinations as well as the modifications of these schemes. The analysis of these schemes has been performed on the basis of a simplified model. This paper presents the analysis of several ARQ schemes using a more complex model which takes into account the long propagation delay (such as satellite links), transmission delay associated with retransmission, the system internal time, and the buffer size of the sending station. A concept of equivalent channel holding time is used in conjunction with a M/G/1 queueing model for the analysis of the system throughput as well as other characteristics.
