Question

Quizplus · Accepted Answer

Selective reject is a useful choice for a satellite link because of the long propagation delay involved. Selective reject allows the receiver to request retransmission of only the lost packets, rather than retransmitting all packets. This is particularly useful for satellite links where the long propagation delay can cause significant retransmission delays and reduce overall throughput.
