Low throughput on links with high propagation delay, as the channel remains idle while waiting for ACKs. 3.2. Go-Back-N ARQ (GBN)
If the sender does not receive an ACK within a designated time (timeout) or receives a NAK, it retransmits the packet. 3. Types of ARQ Protocols 3.1. Stop-and-Wait ARQ Low throughput on links with high propagation delay,
Automatic Repeat Request (ARQ): Reliable Data Transmission 1. Introduction Low throughput on links with high propagation delay,
An Adaptive Type-I1 hybrid ARQ/FEC Protocol - Clemson University Low throughput on links with high propagation delay,
ARQ increases latency due to retransmissions, making it less suitable for real-time applications like VoIP.
