The layer model and error control for satellite communications

This paper is concerned with the location of the layer functions for the satellite computer network in which packet multiple-access scheme is employed. The relation between the layer model and error control is discussed in accordance with the ISO Reference Model. We propose the location of the lower layer functions, where multiple-access, error detection, and retransmission are placed in the connectionless Data Link Layer, and error recovery, sequencing, and flow control are placed in the connection-oriented Transport Layer. By the simulation, it is revealed that the proposed scheme has small overhead and the network delay is reduced by the retransmission in the Data Link Layer.
