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.
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 ...
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.
This interactive animation brings to life the Selective Repeat protocol. In this demo, the sending window limits the sender to a maximum of 5 outstanding, unpacked data packets. To create new data packets, click "Send New". This action will begin moving data packets between sender and receiver.
Jul 25, 2024 · In selective Repeat protocol, if Receives a corrupt packet, it immediately sends a negative acknowledgement and hence only the selective packet is retransmitted. Efficiency of Go-Back-N Protocol is N/(1+2*a)
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 for reliable data frame delivery. Only erroneous or lost frames are retransmitted in this case, while good frames are received and buffered.
Aug 26, 2024 · The main difference between these two protocols is that after finding the suspect or damage in sent frames go-back-n protocol re-transmits all the frames whereas the selective repeat protocol re-transmits only the frame which is damaged.
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?
