A way to throttle network data?

Here's my setup: PC with AMD A10 5800 cpu and more memory than has ever
been used. Internet is DSL modem/router (D2200D), feeding into the PC
through a 100mbit com port. Is there a way that I can throttle a given
program when it is downloading from the net? The reason I ask is that
yesterday I was downloading the Win10 1809 ISO, and I basically could not
access anything else on the net until that download finished. Is there
someway I can partition the network and assign a given data stream only a
percentage of the total bandwidth?

that's what qos (quality of service) is for. most routers support it
but if yours does not, you'll need to get one that does.

My router supports it, but how do I set it? From what I can see all I need
is to be able to tell my ISP to only give that datastream a percentage of
my download speed, so that all my other traffic has some bandwith
available.

I have never noticed the effect you describe even with several devices
sharing an internet connection. Obviously they cannot all do a "full
speed" download at the same time but when downloading something like a
Windows iso it is possible to continue browsing etc without any great
problem. This applies even without a super speed connection as the
system shares out the bandwidth.

QoS as suggested is mostly important when you have a time constrained
activity. For example, if you are streaming live TV or using Skype you
want to give that priority so it does not grind to a halt if you start
downloading a file.

I don't want to throttle by device, I want to throttle by data source,
i.e. Microsoft, bittorrent, IRC, etc. I am paying for 7mb/s download, but
the reality is about 5.7mb/s. What I would like to do is make sure that
when I am receiving data from one of the named sources, I can reserve
like 10% for all other traffic.

qos can be by protocol (bittorrent, http, ftp, voip, etc.).

the 2200 is older and doesn't look like its qos is that flexible. it
should look something like this:

What happens when you google "download manager"?
or "throttle downloads"

https://www.guidingtech.com/45266/id...er-downloader/

Browsers typically let you pause downloads.
But if you require continuous activity, that won't help.

I can give you an observation on this.

Using TCPView from Sysinternals, I've seen Microsoft open
as many as ten to twenty connections while doing Windows Update
or an Upgrade.

A consumer router (like mine) serves connections round robin.
When one machine uses 20 connections and a second machine uses
1 connection, the second machine receives 5% of the WAN bandwidth.

I checked this out, when noticing that machines other than
the Win10 machine were being starved.

This behavior changes from release to release.

You'd need to find a "max_connection" registry setting
or a GPEDit policy of some sort, to reduce the number
of connections being opened.

And each connection can be carrying out a different "package"
download. It's not some normal kind of parallelism. It's
a parallelism at a package level. If an update contains
2000 packages, then there is plenty of opportunity for
the network connection to be pushed hard.

Does QOS solve that ? Dunno. Maybe it needs more of a
quota or a cap of some sort.

That's very interesting. I live in rural New Zealand where my maximum
download speeds vary from less than 1Mbps during the evening to 2.5Mbps
in the small hours of the night. I have to allocate up to 24 hours for a
Microsoft upgrade. But the worst part of it is that during this period I
can't do anything on-line - web pages and my mail servers just time out.
Yet for other largish downloads, not from Microsoft, which might take an
hour or so, I don't have this problem and can use the internet normally
(although "normally" for me is a lot slower than for most people!).

I'd really like to know if there is anything I can do to prevent
Microsoft downloads from completely hogging my bandwidth?

People here see a similar problem with "concurrent TCP" connections
from Windows Update activity. It squeezes out other machines
on your LAN, as described here in the symptoms.

I haven't tried this because I've not had my host severely impacted with
a download (during the download, that is, because at any moment in time
it doesn't matter how large is the download for how long it takes), but
you might go into Task Manager to lower the priority of whatever web
client you are using for the download (e.g., your web browser). The
lower priority simply means other higher priority processes get more
overall time; see:

https://en.wikipedia.org/wiki/Schedu...ive_scheduling

Instead of thinking the huge download is causing the slowdown of your
PC, look in Task Manager and see what is consuming the most CPU cycles.
Might be the web browser, might be your anti-virus, might be something
else that intercepts or interrogates your traffic which you could lower
in priority. If you are using a VPN or configured your host to use a
proxy, that will suck up more CPU cycles than just the network handling.
A process, or several of them, hogging the CPU is going to impact the
responsiveness of your PC.

"into the PC through a 100mbit com port." You're using a DB9 serial COM
port for networking on your PC? That's limited to just 115 Kbps (111
Kpbs is more likely, and with short cables), not 100 Mbps; see
https://en.wikipedia.org/wiki/Serial_port#Speed. Or did you mean a
wired Ethernet CAT5/6 cable to an RJ45 port?

While nospam mentioned setting up QoS at the router, that assigns
priority of network traffic by host, not by process on the host. QoS
give priority to a host but that only applies if you have other hosts
that are also generating lots of traffic. It will have no effect on
your host, even if assigned to QoS, for one process on it hogging the
CPU or data bus. QoS settings at the router haven't a clue about which
process on a host is generating the most traffic. Since you did not
mention having any other hosts connected to your router, your one host
already gets the maximum priority for network traffic. All QoS might do
at the router is assign priority by protocol, so, for example, if you
have a VOIP setup then you could assign those ports more priority to
improve call quality.

QoS would also not help because it is highly likely you are using the
same network protocol (HTTP/HTTPS) to do the download along with your
other "anything else on the net". The Web is not the Internet but many
users call them the same, so I'm assuming "net" means "web" and you're
using the same HTTP protocol for the download and "anything else".
Setting QoS in the router to give priority to HTTP traffic won't
differentiate between the HTTP traffic for the download and HTTP traffic
for "anything else". In that case, start another instance of the web
browser for "anything else" or determine which process for the web
browser is involved with the download and down its priority.
Alternative, and if you have more than one web browser installed, you
could use one web browser to do the download, down its priority (for all
its processes), and use the other web browser for "anything else".

Some web browsers let you throttle their network speed. For Chrome,
see:

https://www.addictivetips.com/web/li...eed-in-chrome/
https://www.guidingtech.com/manage-t...-speed-chrome/

The console frame doesn't scroll, so if it is the left or right side
then you can't get at some of the menus in the toolbar, so down on the
bottom (click "..." and select dock side). Throttling is normally used
to ensure there is enough reserve bandwidth in your network connection
for other network-centric processes, like you're doing a download with
the web browser, you use VOIP for phone calls, you're using an FTP
client to transfer a file, using an NNTP client to retrieve and merge
binaries from Usenet, transferring a backup image to/from cloud storage
(using a dedicated client, not the web browser), and doing all that at
the same time.

https://www.technorms.com/36800/limi...x-chrome-opera

Looks like Firefox requires an extension to throttle its bandwidth.
However, I suspect network throttling in the config of the web browser
means it is applied to all instances of the web browser and across all
tabs, so you'd be slowing down the ISO download but also slowing all
your other connections from that web browser.

If this is a problem with all sustained downloads, not just this time,
then it's possible the current NIC driver (which Microsoft thrust upon
you) has excessive latency. Latency caused by drivers can cause
stuttering. You can use LatencyMon; see:

https://resplendence.com/latencymon

I didn't bother to measure my setup because I'm unlikely to have the
same hardware, driver versions, and OS tweaks as you. We'd be comparing
oranges to tangelos.

I would configure Windows 10 to *NOT* install any drivers. It can pick
the wrong one, like a driver version for rev 1 of a chip but you have
rev 3 that requires a different driver. Reinstall the chipset driver
package from the motherboard/OEM maker that came with the PC, or check
for their latest version and install that. If you feel the need to
update those drivers, do it yourself. Don't let Microsoft change your
drivers.

OK, I have a candidate.

Maybe someone can test this, who is about to bring in a large update
with a ton of separate packages.

Maybe that could reduce the appetite of Windows Update a bit.
It probably goes through BITS for connections.

While nospam mentioned setting up QoS at the router, that assigns

qos can be configured in various ways, including protocol, port, and/or
device, depending on the router. different processes are likely to use
different protocols, so that's mostly by processes.

QoS
give priority to a host but that only applies if you have other hosts
that are also generating lots of traffic. It will have no effect on
your host, even if assigned to QoS, for one process on it hogging the
CPU or data bus.

not true.

QoS settings at the router haven't a clue about which

not necessarily. if the processes are using different protocols and/or

looking at my logs, i see windowsupdate.com via http on port 80, which
i assume is the bulk of the update.

Setting QoS in the router to give priority to HTTP traffic won't
differentiate between the HTTP traffic for the download and HTTP traffic
for "anything else".

yep, but if only http(80) is qos'ed, https(443) would be unaffected,
which is most sites these days.
