What does upstream bandwidth and downstream bandwidth mean?

What is the awareness of upstream and downstream bandwidth, or uplink and downlink speeds? When setting the speed limit of the router and configuring other software, it often encounters the uplink speed and the downlink speed. Many users simply don't know the consciousness represented by the two, let alone the configuration. The following will be detailed for everyone. Introduction.

There are two kinds of behaviors in our process of accessing the Internet: one is to upload data, and the other is to download data. Uplink broadband (speed) refers to the speed of uploading, while downlink broadband (speed) refers to the number of times the downloaded data is.

Uplink bandwidth (speed) and downlink bandwidth (speed) are asymmetric, generally the downlink speed is greater than the uplink speed. The broadband that we usually use says M, which refers to the downlink broadband, because we mainly download data from the Internet, and the amount of data uploaded is much less.

In addition, many users still have such a question, that is, in the process of using broadband, it is found that the speed of downloading in the computer simply does not reach the standard of broadband that they handle, for example, the 10M broadband is processed, and the download speed is only 1M. /s speed, why is this?

This is because broadband operators have different units for downlink speed and downlink speed on Windows computers. The unit of Windows computer is KBbs, and the unit for broadband operation is Kbbs, 1B=8b. For example, if you handle 10M broadband from broadband operation, 10Mbps=10240Kbps/8=1280KBps, so you can download data on your computer. Your maximum download speed is only 1280KBps, which is only about 1M/s. So don't say that the broadband company is crowded, and the broadband deduction is handled. This is only caused by the different units of calculation.

For the early broadband, ADSL is the main technology, the technology limits its uplink to only 512K, so the uplink is fixed, and the later ADSL2+ support uplink is slightly higher, but no matter in Telecom and China Unicom, it seems that there is no big Scale promotion, although the equipment is almost completely ADSL2+ board.

In addition to broadband bandwidth, the download rate of broadband is related to the configuration of the computer, the download software used, the download capacity, and the download network's rate. You can download the software to check your broadband download rate.

Under ideal conditions: the downlink bandwidth of 100M fiber broadband is between 10M/S and 11M/s;

Uplink broadband refers to the speed of uploading to the Internet; the broadband that you want to open is the same as the uplink and downlink. It is not the same; if you don't know, you can consult your carrier; if it is equivalent, your upstream broadband is also 10M/S. Between 11M/s; not equivalent to the general uplink broadband only 400kbs / S to 500Kbs / s.

Note: The general enterprise is open with the same bandwidth for uplink and downlink; the household is not equivalent, generally only the downstream bandwidth, the uplink does not matter.
