Is it true that computers reserve 20 percent of their broadband resources?

This 20% bandwidth is not "reserved", but means that a program that uses a QoS Application Programming Interface (API) can request a maximum of 20% of the bandwidth on each interface base link, but if the program is not fully utilized, the bandwidth can still be used by other programs.

According to Microsoft's Technical Resource Planning (SRP), applications running on Windows XP PCs can share all network bandwidth unless there is an application that specifically requests priority bandwidth. However, if the requesting application does not send data, these "predetermined" bandwidths can still be used for other applications.

By default, the aggregate bandwidth that an application can prescribe for a base link on each interface of the end system is up to 20 percent of the base link speed. If the application that has scheduled the bandwidth does not send enough data to take full advantage of the bandwidth, the unused portion of the scheduled bandwidth will still be available for other data streams on the same host.

Here's Microsoft's explanation for the so-called 20% bandwidth.

The QoS issue in KB316666 is explained as follows:

As with Windows 2000, programs in Windows XP can also take advantage of QoS through the QoS Application Programming Interface (API). All programs can share 100% of the network bandwidth, except for those that specifically require bandwidth priority. This "reserved" bandwidth can also be used by other programs, with the exception of the requester who is sending data.

By default, the program reserves a bandwidth of up to 20 percent of the basic link speed of each interface of the terminal computer. If the amount of data sent by the program with reserved bandwidth is not fully used, the unused portion of the reserved bandwidth can be used for other data streams on the same host.

A bit much, hope it helps!

Yes.. Specifically in **Look I forgot ==. Generally, in order to improve the network speed of the campus, it will be turned off, if it is broadband, don't care, some will be turned off, but the network speed will slow down.

Haven't heard of it, you learned from there.

It's reserved for voice and network management pack QoS anyway, you're not a server, you can optimize it. But Thunderbolt has already been able to handle this 20%, and your other apps won't be at full speed, so it doesn't really make much sense.

This is mainly due to the fact that some background programs need to be connected to the Internet,So that some software can run normally,I now set that 20% reserved bandwidth I set him to 0,Sometimes QQ automatically re-logs in,The game is automatically disconnected。 It is recommended not to change it, but to keep 5 or 10 percent if it is to be changed.

Even if 20% is raised, if the quality of the landlord's network itself is faulty, it will not work.

It's like if you have a lot of energy, you can't use all your energy to work at any time, but of course, you can do the same, and you can think about the result.

Microsoft has designed the operating system to retain 20% of the bandwidth, not that the network card in the computer is reserved for 20% of the bandwidth. The reserved bandwidth of 20 here is not really "reserved", which means that the program that uses the QoS Application Programming Interface (API) in Yu Peichong can apply for a maximum of 20 bandwidth reserved on each interface base link, but if the program is not fully utilized, this bandwidth can still be used by other programs. Obviously, many people misunderstand the real meaning of "reserving 20% of bandwidth".

If you must turn it off, you can follow these steps:

Run the Group Policer program (. In Local Computer Policy, step through the Computer Configuration Administrative Templates Network QoS Packet Scheduler branch. On the right side of the screen will appear the QoS Packet Scheduler policy.

Click Limit Reservable Bandwidth for the subproject on the right. Click Properties next to Show under Throttling Reservable Bandwidth. Click on "Settings".

Settings gives us three options (Unconfigured, Enabled, Disabled), select Enabled, then set the % next to the bandwidth limit to 0%, and press OK to exit.

Click Start Connect to Show All Connections. Select the connection you have established, right-click on the properties, click on the network in the connection properties that appear, and in the network dialog box that appears, check whether the QoS packet scheduler has been ticked in the "This connection uses the following items", and if there is no problem, press OK to exit.

This is mainly due to the need for some background programs to be networked,So that some software can run normally,I now put that 20% of the reserved bandwidth I set the circle to 0,Sometimes Qinghong waits for QQ to automatically log in,The game is automatically disconnected。 It is advisable not to change it.

If you want to change it, you still have to keep 5 or 10 percent.

It's reserved for voice and network management pack QoS anyway, you are not a service cracker and can be optimized.

But the judgment is that Thunderbolt has already been able to get these 20%, and your other applications won't be dismantled at full speed, so it doesn't really make much sense.

The system buffers and needs, and if it's turned on, it should prompt a little bit of network speed

Says who? I haven't heard of it, but it wasn't from the telecom people.
