In your point of view which one is better “Go back n” or “Selective Reject”? Give reasons to support your opinion.Maximum 8 lines.

The Selective-Reject ARQ protocol leads to the highest throughput of the three ARQ protocols. Here, the radio channel has a data rate of v = 6Mbit/s, a packet data size of n = 1514 byte and an unlimited window size is assumed, and the round trip delay trd, is 1 ms. ARQ protocols result in a high system throughput under good channel quality and a very low residual bit error ratio can be guaranteed. The major drawback is the need for a feedback channel and the overhead needed for signaling ACKS. The throughput degrades at low channel quality and packet delay jitter increases with increasing packet error ratio.
