How to limit bandwidth with Windows XP itself

[Gino]

Is there a way to limit network bandwidth from within WinXP itself?
Or do I have to purchase netlimiter?

Thanks

Limit specific apps or as a "Global" setting ? - If Global you can
modify some of the TPC/IP settings which in affect lowers the
available bandwidth.
Not sure your question is specific enough on what you're trying to
achieve.

 

[Gino]

Yes. I would want to do a Global setting. It's one computer that I need to
have limited bandwidth. Where/what settings should I change?
Thanks

Hi
Controlling Bandwidth on a Network is the function of managed hardware, or
and Server, Windows XP being a Client OS can not adequately do so. If you
were more specific in describing you over all goal; might be that some one
can come with an idea.

You might want to read the following to get some insight into
the "Receive Window Size" parameter of TCP/IP:

One of the computers is hogging up too much bandwidth with downloads, webcam
chat, video streaming and slows down other computers.
I want to limit the bandwidth from my cable connection to that one computer
using Windows XP rather than 3rd party software.
Some people recommend Netlimiter to limit the bandwidth that the computer
uses. Is there a setting that can be done to TCP/IP for example or some
other settings or tweaks within Windows XP besides buying a software?
Thanks again.
Hope this clears some points out.

Hi

When you limit the bandwidth to a computer that is mainly busy with File’s
downloads, the download would slow down, but you would get the files.

However, limiting the Bandwidth to a computer that streams audio and video
would probably result with distorted or No streaming.

As mentioned above the Bandwidth usage of a computer can be reduced by
lowering the efficiency of the TCP/IP stack; however, it is not really the
correct approach to such issue.

That's exactly what I would like to do. Lower the bandwidth!
I do not care about the streaming as it shouldn't go on in the first place,
on the other hand slowing down the download speed or the bandwidth would be
great.
Please advise of actions in TCP/IP for Global settings on lowering the
bandwidth.
Thank you.

Hi
Read the page in the above link to the end.
Take into consideration that if you are doing this to some else's computer
it is Not the right thing to do, and can lead to very unpleasant personal
conflicts.

I'm just trying to control my own pc that is in use by my guests.
I want to limit the internet to 10-20kb bandwidth limit.
Thanks for the info.
I read what's on the website and I think DrTCP would do the job, but what
should I set the TCP RWIN size for the bandwidth to be from 10-20kb.
Would you recommend another setting?

Thanks for your help.

To be exact:
I have 2 pc's at home. 1 is my own, second is used by my guests.
I want to limit the second(guest) pc with lower connection so it won't
interfere with my connection so much.
I was reading the posts and noticed that RWIN setting should do the job.
Hope I'm right to choose this.
However I can't find information on the RWIN settings. There are settings
for DSL, Cable, and Dialup. I want the connection to be at about 20kb
bandwidth.

Is there a site that shows speeds that correspond with RWIN settings other
than DLS Cable or Dialup?

Thanks again
Gino

Go here
http://www.numion.com/YourSpeed3/index.html

Run Quickstart. Maybe a couple times to get a good average. Note
speed. Write down any settings before you change them so if it
breaks you can go back to the original.

Make a change to whatever setting you desire. Run Quickstart again
and see what difference it makes. Repeat until you are happy.

RWIN size of 1500 is equal to what size of bandwidth?
This is what I'm trying to find out, some ratios.
If I have RWIN size of 200 for example, what would be the bandwidth for
that?
I am trying to understand how the ratio works.
Thanks

You might look into your router's settings - apply lower priority to the
guest machine, high priority to yours. In the case of my Linksys router,
specific applications/ports can be finetuned in this manner.

You won't be able to set an absolute bandwidth value, but it might help
enough.

But why are you looking for a technical solution to something that is as
simple as saying to your guest, "Please don't do that"
