This article will explain in detail how to use tcp window scaling to improve network bandwidth in Linux. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

When TCP was first invented, the network bandwidth in the world was very small, so the largest acceptance window was defined as 65535 bytes. With the revolutionary progress of hardware, 65535 has become a performance bottleneck, while the TCP header only leaves 16bit for the receive window value. The solution is to tell each other your Window Scale during the three-way handshake. Window Scale is placed in the Options outside the TCP header, declares a Shilt count to the other party, takes it as an exponent of 2, and then leaves the receive window defined in the TCP header to get the real TCP receive window.

103.86.70.43 tells 192.168.9.135 that its Shilt count is 6Magne2 to the 6th power equals 64, which means that the receiving window declared by 103.86.70.43 will have to be multiplied by 64 to be the real receiving window.

103.86.70.43 declares his receiving window Window size value: 477,47764 / 30528, so Wireshark displays win=30528

With regard to the receive window, 103.86.70.43 declares to 192.168.9.135 that its receiving window is 30528192.168.9.135, then it will limit its sending window to 30528.

So much for sharing about how to use tcp window scaling to improve network bandwidth in Linux. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
