Sliding window protocol is a data transmission protocol feature that provides reliable in-order delivery of packets. It is used in Transmission Control Protocol and data link layer protocols. It is useful when there is a significant amount of traffic on a network and it requires a reliable way to deliver packets in a certain order. This protocol is a good choice when multiple packets must be delivered at once. Sliding window protocol is widely used and is used in most modern Internet protocols.
In general, the sliding window approach consists of maintaining a window that satisfies the constraints of a problem and attempting to stabilize the window whenever it violates the constraints. In this way, it is possible to find a substring that has all the characters of another string, or an anagram of another string.
The sliding window protocol has several advantages. The most important is that it does not impose a fixed window size. Instead, the window size is adjusted according to the number of received packets and the rate of processing for the receiver. However, this limitation has a drawback: the sliding window protocol limits the effective throughput by reducing transmission speed. The receiver also has to wait for an acknowledgement from a sender.
Another reason why this method is useful is because it reduces the complexity of algorithms for arrays and lists. Its complexity is reduced to O(n) and it can solve many problems faster than brute-force solutions. This technique allows for the computation of running averages, creating a set of all adjacent pairs, and other algorithms that involve lists or arrays.
Sliding windows are easy to operate and require low maintenance. However, cleaning is difficult from the outside of the window, as it can be hard to reach the interior of the window. Sliding windows are generally made of aluminum or powder-coated steel, and they are available in different types of glass. They can also be locked for a tight seal.
Sliding windows are a popular choice for many homeowners. They provide a wide view of nature and are easy to operate. They are also ideal for areas where there is limited space. In addition to being aesthetically pleasing, sliding windows can provide excellent energy efficiency. They can be a great choice for traditional and contemporary homes.
Sliding window methods are also used in Go-Back-N ARQ (Automatic Repeat Request) protocol. It uses the sliding window method to communicate with a network. Using the sliding window method, a sender sends frames one to five before the receiver can receive knowledge of frame one. This method can work well when there are fewer errors, but may lose some bandwidth when the receiver sends a frame again.
Another technique used for data transmission using this technique is Transmission Control Protocol (TCP). It is a packet-based protocol that controls data packets between two network devices. Using a sequential number to identify missing data at the receiving end, this technique prevents duplicated data and ensures that packets arrive in a reliable manner.
When a packet is received, the sender adjusts the send window to include the next data packet. The send window slides along the data segment from left to right. During this process, the sender continuously responds to ACK messages from the receiver. The ACK message contains information about the received packet. It also specifies the size of the receive window. It can apply to multiple packets or to a single packet.
