What does linux tx value mean?

Linux tx value has many meanings, for example: 1. The tx of wan is the upload speed of the workstation to the ISP via the ros wan network card, that is, the upload speed; 2. The rx of the intranet network card lan is ros Accepts uploads from intranet workstations, and tx is the speed of the lan network card transmitted to the workstation, that is, the download speed of the workstation through the intranet network card. Each version of tx rx is different.

What does the linux tx value mean?

Detailed explanation of the meaning of Tx and Rx for network card traffic in Linux system

In the Linux environment system, we often cannot distinguish tx and rx clearly when using software to view network card traffic. respectively.

In fact, the normal explanation is:

tx is sending (transport), rx is receiving (receive). Take the debain system as an example. For example, if your external network card, wan, rx, wan accepts the transmission data from the ISP, that is, the download speed. Wan's tx is the speed at which the workstation uploads to the ISP via the ros wan network card, that is, the upload speed. The rx of the intranet network card lan should be ros accepting uploads from the intranet workstation, which is the upload speed. tx is the speed that the lan network card transmits to the workstation, that is, the download speed of the workstation via the intranet network card (debain). tx rx Each version is different. And the explanations for the external network and the internal network are opposite. Just remember that generally RX external network refers to downloading, TX refers to uploading and the internal network is the opposite.

The following example is where we use bwm The traffic status of the relevant network card viewed by -ng software.

The Rx and Tx displayed by network cards such as tap150i0 represent: Rx outgoing traffic Tx incoming traffic, which is the opposite for eth0 above.
