Aug 31, 2023 · An alternative strategy, the selective repeat protocol, is to allow the receiver to accept and buffer the frames following a damaged or lost one. Selective Repeat attempts to retransmit only those packets that are actually lost (due to errors) : Receiver must be able to accept packets out of order.

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. Finally, we’ll highlight some crucial advantages and disadvantages of this protocol.
Selective Repeat Protocol (SRP) is a type of error control protocol we use in computer networks to ensure the reliable delivery of data packets. Additionally, we use it in conjunction with the Transmission Control Protocol (TCP)to ensure that the receiver receives data transmitted over the network without errors. In the SRP, the sender divides the ...
Now let’s discuss the steps involved in the SRP. The first step is to divide data into packets.The sender divides the data into packets of a fixed size. When the sender divides the data into packets, it assigns a unique sequence number to each packet. The numbering of packets plays a crucial role in the SRP. The next step is to send the packets to ...
Let’s see how we can transmit data using the SRP. We divide our sample data into 6 data packets or frames: Additionally, we’re assuming the window size for the receiver and sender is 2.Hence, we transmit two frames and wait for the receiver to acknowledge the frames transmitted before sending the next frames. In case of a missing or unacknowledged ...
The SRP offers several advantages over other error control protocols, including efficient retransmission, selective acknowledgments, reduced delay, and higher throughput. The main difference with other error control protocols is that it only retransmits lost packets rather than retransmitting the entire set of packets. As a result, the SRP reduces ...

Nov 1, 2023 · Learn what selective repeat ARQ is, how it works, and its advantages and disadvantages. See an example of selective repeat protocol and compare it with other ARQ techniques.
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.
Learn how selective repeat protocol works as a sliding window protocol that resends only the lost or corrupted packets. Compare it with go-back-n protocol and see an example of selective repeat operation.
Sep 11, 2024 · 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.
