Throughput of a satellite channel-communication (Q798292)

The throughput of a satellite channel communication is depending upon the link protocol. It is well known that the ''classical'' HDLC protocol is inadequate when applied to satellite links instead of short terrestrial links. Several modifications have been proposed to overcome this problem. The present paper gives an analysis and evaluation of a new class of protocols called ''Virtual Subchannel schemes'' which splits the satellite link into several components; these subchannels are assigned for transmission in cyclic order and are controlled independently of each other by the classical HDLC procedure.
