, which is the core of these policies. 2.1. Issues with ACK when transmitting data
Before explaining the sliding window, it is necessary to look at the ACK response strategy, in general, the sending side sends a TCP datagram, then the receiving end should send an ACK datagram. But in fact it is not the case, the sender will continuously send the data to fill the receiver's buffer, and the recipient of the d
the concept of ARQ and sliding windows
Sliding Window Protocol is a traffic control method used by TCP. This protocol allows the sender to send multiple groupings consecutively before stopping and waiting for confirmation. Because the sender does not have to stop every time a packet is made to wait for confirmation, the protocol can speed up the transfer of data.

1. The Concept sliding window protocol, also known as the fallback N-step Protocol (GO-BACK-N,GBN), allows the sender to send multiple groupings (when multiple groupings are available) without waiting for confirmation, but it is limited to the number of unacknowledged groupings in the pipeline that cannot exceed a certain maximum allowable number of N. The
A very important field in the header of TCP is the size of a 16-bit long window. It appears in each TCP datagram and matches the 32-bit validation serial number, it is used to notify the peer about the size of the Receiving Window of the local socket. That is to say, if the local socket sends a TCP data, the 32-bit validation serial number is 5, and the window si
the input frame contains data, d e l I v e r s w p first calls m s g s t r I p H D R and l o a D _ S W P _ H D r so that extract the header. Routine l o a D _ s w p _ h d r corresponds to the previously discussed S t o r e _ s w p _ h d r, it converts a byte string into a C-language data structure containing the s w p header. Then, d e l I v e r s w p calls s w p I n wi n d o w to ensure that the frame sequence number is within the expected sequence number range. In this case, the routine loops

An example shows the relationship between the sending buffer, the receiving buffer, and the sliding window protocol.
In the previous articles, I briefly introduced the relationship between the above concepts in TCP network programming and the behavior of several basic socket system calls. Here I will give an example, for each tcp socket, there is a sending buffer and the receiving buffer corresponding to it
