The Sliding Window Protocol is a key computer networking technique for controlling the flow of data between two devices. It guarantees that data is sent consistently and effectively, allowing many packets to be sent before requiring an acknowledgment for the first, maximizing the use of available bandwidth.
Transmission Delay (Tt)– Time to transmit the packet from the host to the outgoing link. If B is the Bandwidthof the link and D is the Data Size to transmit Propagation Delay (Tp)– It is the time taken by the first bit transferred by the host onto the outgoing link to reach the destination. It depends on the distance d and the wave propagation spee...
In Stop and Wait protocol, only 1 packet is transmitted onto the link and then sender waits for acknowledgement from the receiver. The problem in this setup is that efficiency is very less as we are not filling the channel with more packets after 1st packet has been put onto the link. Within the total cycle time of Tt + 2*Tp units, we will now calc...
As we have seen above, All the packets in the current window will be given a sequence number. Number of bits required to represent the sender window = ceil(log2(1+2*a)). But sometimes number of bits in the protocol headers is pre-defined. Size of sequence number field in header will also determine the maximum number of packets that we can send in t...
There are two types of Sliding Window Protocol which include Go-Back-N ARQ and Selective Repeat ARQ:
Efficiency: The sliding window protocol is an efficient method of transmitting data across a network because it allows multiple packets to be transmitted at the same time. This increases the overal...Reliable: The protocol ensures reliable delivery of data, by requiring the receiver to acknowledge receipt of each packet before the next packet can be transmitted. This helps to avoid data loss or...Flexibility:The sliding window protocol is a flexible technique that can be used with different types of network protocols and topologies, includingwireless networks,Ethernet,and IP networks.Congestion Control: The sliding window protocol can also help control network congestion by adjusting the size of the window based on the network conditions.Complexity: The sliding window protocol can be complex to implement and can require a lot of memory and processingpowerto operate efficiently.Delay:The protocol can introduce a delay in the transmission of data, as each packet must be acknowledged before the next packet can be transmitted. This delay can increase the overall latencyof th...Limited Bandwidth Utilization: The sliding window protocol may not be able to utilize the full available bandwidth of the network, particularly in high-speed networks, due to the overhead of the pr...Window Size Limitations:The maximum size of the sliding window can be limited by the size of the receiver’s buffer or the available network resources, which can affect the overall performance of th...The Sliding Window Protocol is a crucial technique for assuring reliable and efficient data delivery in computer networks. Allowing many packets to be delivered before demanding acknowledgments and maximizes bandwidth use and minimizes delays. This protocol, which is implemented in forms such as Go-Back-N ARQ and Selective Repeat ARQ, maintains a b...
Learn about the sliding window protocol, a key computer networking technique for reliable data transmission. It allows multiple packets to be sent before an acknowledgment, increasing efficiency and bandwidth.
Learn about the sliding window technique for sending multiple frames at a time, and the two types of sliding window protocol: Go-Back-N ARQ and Selective Repeat ARQ. Compare their features, advantages and disadvantages, and examples.
Learn about the basic concept, motivation and operation of sliding window protocols, a feature of packet-based data transmission protocols. Sliding window protocols allow a selected number of packets to be sent without waiting for an acknowledgment, improving efficiency and reliability.
1. Preface. We are about to discuss a series of protocols used between a pair of directly-connected sender and receiver. These protocols serve three purposes. to guarantee delivery reliability, to enforce correct ordering of frames delivered to the network layer at the receiving end, and. to provide flow control. 2. Stop And Wait.

Jan 9, 2021 · As a class, protocols where one side implements retransmit-on-timeout are known as ARQ protocols, for Automatic Repeat reQuest. In addition to reliability, we also want to keep as many packets in transit as the network can support. The strategy used to achieve this is known as sliding windows.
