Nov 1, 2023 · Selective Repeat ARQ. It is also known as Sliding Window Protocol and used for error detection and control in the data link layer. In the selective repeat, the sender sends several frames specified by a window size even without the need to wait for individual acknowledgement from the receiver as in Go-Back-N ARQ. In selective repeat protocol ...
Aug 31, 2023 · Selective Repeat Protocol (SRP) : This protocol (SRP) is mostly identical to GBN protocol, except that buffers are used and the receiver, and the sender, each maintains a window of size. SRP works better when the link is very unreliable.
Selective Repeat ARQ is also known as the Selective Repeat Automatic Repeat Request. It is a data link layer protocol that uses a sliding window method. The Go-back-N ARQ protocol works well if it has fewer errors.
Mar 18, 2024 · In this tutorial, we’ll discuss a protocol used for the reliable delivery of data packets in networks: Selective Repeat Protocol (SRP). Furthermore, we’ll present an example of packet transmission using the SRP.
Selective repeat protocol is a sliding window protocol that uses the concept of pipelining where multiple packets can be sent while the sender is waiting for the acknowledgement for the first sent packet. The selective repeat protocol manages error and flows control between the sender and receiver.
In the Selective Repeat ARQ protocol, ARQ stands for Automatic Repeat Request. ARQ is an error-control strategy that ensures that a sequence of information is delivered in order and without any errors or duplications despite transmission errors and losses.
Jun 27, 2023 · 2. What is the Selective Repeat Protocol? The Selective Repeat Protocol is a flow control mechanism used in data communication. It allows for the retransmission of specific lost or corrupted packets, rather than requiring the retransmission of the entire data stream. 3. How does the Selective Repeat Protocol improve reliability?
Nov 23, 2021 · The selective repeat protocol is an implementation of the sliding window protocol. In the selective repeat protocol, both the sender and the receiver maintain a window of outstanding and acceptable sequence numbers.
Jul 30, 2019 · 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.
Selective Repeat protocol or SR protocol is an implementation of a sliding window protocol. The features and working of this protocol are explained in the following points- Point-01: In SR protocol, sender window size is always same as receiver window size. Sender window size = Receiver window size.
