Jun 8, 2021 · ARQ stands for Automatic Repeat Request also known as Automatic Repeat Query. ARQ is an error-control strategy used in a two-way communication system. It is a group of error-control protocols to achieve reliable data transmission over an unreliable source or service. These protocols reside in Transport Layer and Data Link Layer of the OSI(Open System Interconnection) model. These protocols are responsible for automatic retransmission of packets that are found to be corrupted or lost during ...
ARQ is able to change its behaviour in response to dynamic network situations like signal quality changes or congestion. ARQ can preserve a constant level of service quality by requesting retransmissions as necessary. 5. Ordered Delivery: Data packets are delivered in a specific order thanks to ARQ.
