How to set the reception window for selecting the replay protocol?
In the selection of the re-transmission protocol, the receiving window size must satisfy 1
What is the window size for selecting the replay protocol?
For the selective replay protocol, the window size was <=2^(m - 1), and the transmit window could not be larger than the receive window. To maximize efficiency, in most cases, the transmit window was equal to the receive window and was equal to 2n - 1 (n was the number of bits used to number the frame). However, this value must not exceed half of the range of the serial number to avoid the overlap of the new and old receive windows at the receiver. "Choose" was equally exciting.

Choose which layer to set the replay protocol on
The selection of the replay protocol was set at the transport layer. Transmission layer protocol such as the Transmission Control protocol (TCM) used a packet replay strategy to deal with problems in network transmission to ensure reliable data transmission. Choosing a replay protocol was a way to achieve reliable transmission. It used a specific mechanism to ensure that only the wrong frames were retransmitted during the data transmission process to improve transmission efficiency. These operations were within the scope of the transmission layer. "Choose" was equally exciting. Everyone was welcome to read it!
How to set the range of the frame number for selecting the replay?
If n bits are used to number the frames, in order to prevent the new receive window from overlapping with the old receive window after the receiver moves the window forward, the maximum size of the transmit window should not exceed half of the range of the sequence number, that is, WT< 2n-1. When the transmit window is the maximum, it is the same as the receive window. In most cases, the transmit window is equal to the receive window and is equal to 2n-1, because the maximum efficiency can be achieved in this case. Here, n represents the number of digits of the frame number, and the setting of the frame number range is related to this n, and must satisfy the above restrictions on avoiding window overlap.

Choose which layer the replay protocol is on
The selective replay protocol was a transport layer protocol. It was a specific example of automatic repeat request (ARQ), which could be used for message unit transmission and confirmation. It was designed to deal with problems such as packet loss, wrong packet, and disorder during network transmission to ensure reliable data transmission. In this protocol, the sending process continuously sends a number of frames according to a window of a specified size, and the receiving process continues to receive and confirm frames after an error occurs. Different from the Fallback N-frame protocol (GGN), it sets up a single acknowledgment, increases the receiving window, and designs a receive buffer to buffer the frames that arrive out of order. This allows only the wrong frames to be retransmitted, thereby improving transmission performance. "Choose" was equally exciting. Everyone was welcome to read it!
Continuous arq protocol and sliding window protocol
In the continuous ARQ protocol, the sender maintained a sending window of a certain size, and the packets within the window could be sent continuously without waiting for the other party's acknowledgment. The sender would slide the sending window forward by one packet every time it received an acknowledgment. The receiver usually uses the method of accumulating acknowledgement, that is, after receiving several packets, it sends an acknowledgement to the last packet that arrives in order, indicating that all the packets up to this packet have been received correctly. However, this method has shortcomings. For example, when the middle packet is lost, the sender cannot know the situation of the subsequent packets, and may need to re-transmit more packets. The sliding window protocol involves a sending window and a receiving window. The transmit window is the range of sequence numbers of the frames that have been sent but have not been acknowledged, and the receive window is the range of sequence numbers of the frames that are expected to be received. When the default window size is 1, you can operate according to the specific sending process. The sliding window protocol could improve the channel utilization and was a reliable transmission mechanism for data communication. The continuous ARQ protocol can be seen as a specific application form of the sliding window protocol under certain conditions (such as the cumulative acknowledgment method). They are all protocol mechanisms that exist to achieve effective and reliable data transmission in the network. "Choose" was equally exciting. Everyone was welcome to read it!

arq protocol sending window maximum
In the ARQ protocol, the maximum transmission window is related to the type of the protocol. 1. ** Stop and Wait ARQ protocol **: After sending a frame, the sending station must wait for an acknowledgment signal. After receiving an acknowledgment signal, it will continue to send the next frame. There is no mention of the maximum value of the sending window size. 2. ** Repeat ARQ protocol **: It is a combination of sliding window technology and automatic repeat request technology. The maximum sending window is 2^(n - 1)(considering the possible loss of the ACK, it will be repeated after a time limit). 3. ** Continuous ARQ protocol (includes two types of protocol: - For the backward N-frame protocol, 1 <transmission window <= 2n- 1. - For the selective replay protocol, the transmit window is <= 2^(n - 1), and when the transmit window is the maximum, the receive window = transmit window = 2n - 1.

selecting the sky
" Choosing the Heavens " was an oriental fantasy novel written by Maoni. The story took place in a fictional world where humans, demons, and devils coexisted. In order to defy the heavens and change his fate, the protagonist, Chen Changsheng, had come to the Fairy's Capital to fight against the dark forces with a group of heroic youths. The novel was later adapted into an ancient fantasy drama, with Lu Han and Gulnazar leading the roles. The drama was broadcast on Hunan TV in April 2017. As for the specific plot and the content of the latest chapter, I'm not sure.
