The Transmission Control Protocol uses a variant of Go-Back-N ARQ to ensure reliable transmission of data over the Internet Protocol, which does not provide guaranteed delivery of packets; with Selective Acknowledgement (SACK), it uses Selective Repeat ARQ. IEEE 802.11 wireless networking uses ARQ retransmissions at the data-link layer. ITU-T G.hn uses hybrid ARQ, a mixture of high-rate forward error correction (FEC) and ARQ. It is … Web25 lug 2024 · Both L2 (Data Link Layer) and L4 (Transport Layer) do flow control. It's probably well known that TCP (L4) does flow control using sliding window protocol.Together with congestion control, TCP makes great effort to raise transmission efficiency..
