What is sliding window protocol what should be the size of window?
What is sliding window protocol what should be the size of window?
In this protocol, the size of the sender window is always equal to the size of the receiver window. The size of the sliding window is always greater than 1. If the receiver receives a corrupt frame, it does not directly discard it. It sends a negative acknowledgment to the sender.
Which protocol uses sliding window?
Transmission Control Protocol (TCP)
Transmission Control Protocol (TCP) uses a sliding window for flow control. Before you tune any TCP/IP settings, first understand how the TCP sliding window works. The TCP sliding window determines the number of unacknowledged bytes, x , that one system can send to another.

What is the sliding window algorithm?
The Sliding Window algorithm is one way programmers can move towards simplicity in their code. This algorithm is exactly as it sounds; a window is formed over some part of data, and this window can slide over the data to capture different portions of it.
What are the advantages of sliding window protocol?
The sliding window provides several benefits:
- It controls the speed of transmission so that no fast sender can overwhelm the slower receiver;
- It allows for orderly delivery, as we will show;
- It allows for retransmission of lost frames, specific retransmission policy depends on the specific implementations.
What is the purpose of sliding window protocol?
Sliding window protocols are used where reliable in-order delivery of packets is required, such as in the data link layer (OSI layer 2) as well as in the Transmission Control Protocol (TCP). They are also used to improve efficiency when the channel may include high latency.
How do I know if I have a sliding window problem?
Sliding Window Algorithm – Practice Problems
- Find the longest substring of a string containing k distinct characters.
- Find all substrings of a string that are a permutation of another string.
- Find the longest substring of a string containing distinct characters.
When should you use a sliding window?
When can we use it? Generally speaking, the sliding window technique is useful when you need to keep track of a contiguous sequence of elements, such as summing up the values in a subarray.
Are sliding window protocols full duplex?
Sliding Window protocol is full duplex in nature.
Why do you limit the window size in Go Back N and selective repeat sliding window ARQ?
Window size should be less than or equal to half the sequence number in SR protocol. This is to avoid packets being recognized incorrectly. If the windows size is greater than half the sequence number space, then if an ACK is lost, the sender may send new packets that the receiver believes are retransmissions.
How pipelining property is used in sliding window protocol?
Pipelining
- Go-Back-N: Go-Back-N(GBN) is a ‘Sliding Window Protocol’ that ensures pipelining. It first checks the window size of the sender and receiver, and then it sends multiple data frames at the same time.
- Selective Repeat: Selective Repeat is also a sliding window protocol implementing pipelining.
What is sliding window protocol and why it is better than simplex protocol?
In Sliding window protocol, sender sends multiple frames at a time and retransmits the damamged frames. Stop and Wait protocol is less efficient. Sliding Window protocol is more efficient than Stop and Wait protocol. Sender’s window size in Stop and Wait protocol is 1.
How is sliding window protocol used in Computer Engineering?
Computer Engineering Computer Network MCA Sliding window protocols are data link layer protocols for reliable and sequential delivery of data frames. The sliding window is also used in Transmission Control Protocol. In this protocol, multiple frames can be sent by a sender at a time before receiving an acknowledgment from the receiver.
Which is sliding window protocol does javatpoint use?
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. But if there is a lot of error in the frame, lots of bandwidth loss in sending the frames again. So, we use the Selective Repeat ARQ protocol.
Which is ARQ protocol uses sliding window method?
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.
What is the size of a sliding window?
If the sequence number of the frames is an n-bit field, then the range of sequence numbers that can be assigned is 0 to 2 ? −1. Consequently, the size of the sending window is 2 ? −1. Thus in order to accommodate a sending window size of 2 ? −1, a n-bit sequence number is chosen.
