Mar 31, 2024 · Selective repeat protocol, also known as Selective Repeat Automatic Repeat Request (ARQ), is a data link layer protocol that uses the sliding window technique.
Nov 1, 2023 · What is selective repeat ARQ in computer networks - Selective-repeat Automatic Repeat Request (ARQ) is one of the techniques where a data link layer may deploy to control errors.Techniques to control ARQGenerally, there are three types of techniques which control the errors by Automatic Repeat Request (ARQ) they are −Stop-and-wait ARQGo-Back-N ARQS
Aug 31, 2023 · Figure – the sender only retransmits frames, for which a NAK is receivedEfficiency of Selective Repeat Protocol (SRP) is same as GO-Back-N’s efficiency : Efficiency = N/(1+2a) Where a = Propagation delay / Transmission delay Buffers = N + N Sequence number = N(sender side) + N ( Receiver Side)
Sliding Window Protocol. The sliding window is a technique for sending multiple frames at a time. It controls the data packets between the two devices where reliable and gradual delivery of data frames is needed.
Mar 18, 2024 · Learn about a protocol used for the reliable delivery of data packets in networks: Selective Repeat Protocol (SRP).
Nov 23, 2021 · Sliding Window Protocol (Selective Repeat) - The sliding window protocol is a flow control protocol that allows both link nodes A and B to send and receive data and acknowledgments simultaneously.Here, the sender can send multiple frames without having to wait for acknowledgments.If no new data frames are ready for transmission in a specified
The article by Scaler Topics covers topics such as introduction to Selective Repeat ARQ and the working of Selective Repeat ARQ.
1. Sender Window. The sender window in selective repeat is much smaller as compared to the go-back-n protocol. The size of the sender window here is 2 m-1.Here m is the number of bits used by the packet header to express the sequence number of the corresponding packet.
Jul 30, 2019 · A Protocol Using Selective Repeat - Selective repeat protocol, also called Selective Repeat ARQ (Automatic Repeat reQuest), is a data link layer protocol that uses sliding window method for reliable delivery of data frames. Here, only the erroneous or lost frames are retransmitted, while the good frames are received and buffered.It us
Mar 18, 2023 · S.NO Go-Back-N Protocol Selective Repeat Protocol; 1. In Go-Back-N Protocol, if the sent frame are find suspected then all the frames are re-transmitted from the lost packet to the last packet transmitted.: In selective Repeat protocol, only those frames are re-transmitted which are found suspected.: 2. Sender window size of Go-Back-N Protocol is N. Sender window size of selective Repeat protocol is also N.
