    Aug 9, 2024 · In Stop-and-Wait ARQ, the sender assigns sequence numbers to each data frame it sends. This allows the receiver to identify and acknowledge each frame individually, ensuring reliable delivery of data packets.

    May 29, 2023 · Stop & Wait ARQ is a 1-bit sliding window protocol where the size of the sender window as well as the receiver window is 1. Thus, in Stop & Wait ARQ technique, the minimum number of sequence numbers required is equal to the sum of the sender window size & receiver window size.

    Jul 25, 2024 · Maximum window size = 1 + 2*a where a = Tp/Tt Minimum sequence numbers required = 1 + 2*a. All the packets in the current window will be given a sequence number. Number of bits required to represent the sender window = ceil(log2(1+2*a)).

    Jun 8, 2021 · Stop and Wait ARQ is a Sliding Window Protocol method used for the reliable delivery of data frames. The stop-and-wait ARQ is used for noisy channels or links to handle flow and error control between sender and receiver.

    To avoid these problems, the most common solution is to define a 1 bit sequence number in the header of the frame. This sequence number alternates (from 0 to 1) in subsequent frames. When the receiver sends an ACK, it includes the sequence number of the next packet it expects.

    Request Numbers Are Required On ACKs To Distinguish Packet ACKed • REQUEST NUMBERS: – Instead of sending "ack" or "nak", the receiver sends the number of the packet currently awaited. – Sequence numbers and request numbers can be sent modulo 2. This works correctly assuming that 1) Frames travel in order (FCFS) on links
