How I can limit Download/Upload bandwidth?


Creating rules that allow you to distribute internet bandwidth and prevent misuse is one of the most important tasks for a Network Administrator.

SafeSquid is an ideal solution for getting such policies enforced, very easily.

Consider this for an example-

You as an administrator require this policy to be enforced -

Policy 1:

Disallow Smith from downloading any file if its size is more that 20 MB.

But Smith may download any number of files smaller than 20 MB,

But not aggregating over 300Mb in any given week, which includes a maximum of 50Mb of MP3 music files.

Policy 2:

Allow Jack to download any file of any size from

But Jack should not download any file of size more than 12 MB

However, Jack may download any number of files that are smaller than 12 MB from any other web-site

But not aggregating over 50Mb in a day.

This is a typical...

Unless you are living in some awesome city, most of the Internet connections are of low bandwidth, maybe a couple “Mbps” on average. Managing all those applications in your Windows system to use that limited bandwidth is a real pain. Though you have all sorts of features in Windows, there is no option that lets you control which app uses what amount of bandwidth. Sure, you can completely block an app using the built-in Windows firewall or a third-party firewall software, but that doesn’t work for everyone as you want those apps to access the Internet.

Here is how you can limit certain applications using up all your bandwidth.

In order to limit bandwidth to select applications in Windows, we are going to use a third party application called Net Balancer. The free or unregistered version of this app is capable of limiting up to three processes at any given point of time, which is good enough for most home users.

To start, head over to the official website and...

There are good reasons to look at the "Internet facing router" approach for managing a network as a whole - however as the original question was specific and the user may very well be the only computer on the network, that is a secondary concern.


Per one of the other top answers, for a while I tested out NetBalancer. It works really well - and is easy to configure.

NetBalancer is available for purchase on their web page for about $50. The trial/free version allows you to monitor connections - but does not allow throttling.


The alternative is NetLimiter. It has a free trial period - but starts at ~$20 for the Lite version or ~$30 for the Pro version. NetLimiter is the tried-and-tested go-to application for many SysAdmins.

When NetLimiter's trial ends, until you buy a license, it becomes a monitoring-only tool - and no longer supports throttling. This can still be useful - but not for this use case.

Example 3: Uploading a 19 MB mp4 file to our FTP server using with and without trickle.

In this example we will use the freely-distributable “He is the gift” video, available for download from this link.

We will initially download this file to your current working directory with the following command:

# wget

First off, we will start the trickled daemon with the command listed above:

# trickled -d 30 -u 10

Without trickle:

# ncftpput -u username -p password /testdir 2014-00-1460-he-is-the-gift-360p-eng.mp4


2014-00-1460-he-is-the-gift-360p-eng.mp4: 18.53 MB 36.31 MB/s

With trickle:

# trickle ncftpput -u username -p password /testdir 2014-00-1460-he-is-the-gift-360p-eng.mp4


2014-00-1460-he-is-the-gift-360p-eng.mp4: 18.53 MB 9.51 kB/s

As we can see in the output above, the upload transfer...

I noticed yesterday that the popular live streaming software Sopcast was using all of my computer's upload bandwidth. The program uses P2P technologies to distribute the live stream to all connected users, just like the newly announced Bittorrent Live does.

Using all of my computer's upload speed, 10 Mbit in total, put a lot of strain on other programs that used the Internet connection (I discovered this with the help of Netspeed Monitor).
This can cause problems if you share the connection with other users, or run programs in the background that require a certain amount of upload speed to function properly and without lags. Maxing out your upload bandwidth can also cause problems with your ISP as they may limit your connection or ask you to upgrade to an account that is more expensive.

I first tried to find an option in Sopcast itself to limit the upload bandwidth, but there was none unfortunately. Research on the Internet revealed a handful of commercial...

Limiting the Bandwidth on an Egress Interface

You can limit the bandwidth on an egress port. For example, if a customer pays only for a small percentage of a high-speed link, you can limit the bandwidth to that amount.

Note The egress queue default settings are suitable for most situations. You should change them only when you have a thorough understanding of the egress queues and if these settings do not meet your QoS solution.

Beginning in privileged EXEC mode, follow these steps to limit the bandwidth on an egress port. This procedure is optional.

To return to the default setting, use the no srr-queue bandwidth limit interface configuration command.

This example shows how to limit the bandwidth on a port to 80 percent:

Switch(config)# interface gigabitethernet2/0/1

Switch(config-if)# srr-queue bandwidth limit 80

When you configure this command to 80 percent, the port is idle 20 percent of the time. The line rate drops to...

Test your download, upload and latency from a mobile phone up to optical fiber, and everything between. This test is pure HTML5

This test requires your browser's full attention for accurate results. Run the test when your network is quiet, and don't switch to other applications or change browser tabs during the test. A few Windows security and privacy software packages can block the test or slow the browser.

You have a poorly written browser extension installed, there is missing functionality


Welcome to the speed test that tests


speed not just speed to your ISP.

A complete test takes less than 45 secondsIf you switch tabs during the test, it will stop (blame the browser!).Past tests will show up in this space, so start building your history.We test more than just top speed.


This test needs a modern (recent) browser. If it hangs under Windows, please temporarily disable any browser extentions or...

The scenario is common in this Internet age. The family gets together to watch the latest movie on Netflix, only to have the viewing experience spoiled by video buffering and stuttering. You check the Internet speed at your house, and the bandwidth looks fine. So what gives?

Well, the problem might be with your home network. After looking at your router management software you see that everyone has their smartphone, tablet, and laptop simultaneously active on the network. The Netflix movie you are watching can’t get enough bandwidth to stream properly, forcing you to deal with buffering and poor video resolution.

What steps can you take to optimize the performance of your home network?

Limit the Number of Devices active on your Network

An easy way to maximize bandwidth before streaming a movie or TV show is to limit the number of devices on your network. Is Billy in the basement playing Call of Duty online with his friends? Great, kick his PS4 off the...

There are 2 large issues with this. First there is likely no way to prevent someone who is determined to get past the restrictions. You would have to have some form of user based authentication and then limit on userid rather than mac or ip address which can be changed at will. The second problem is this is long term (from a data routers perspective) data. A router does not have a hard drive to store this information so you generally need a firewall that has a drive to store this data though a power outage or reboot.

The only cheap solution that may partially work is called gargoyle. It is a special open-wrt firmware version that has the ability to do quotas. I know little about it, has been on my list of things to play with that I never got around to.

Be aware I do not know how or if it solve the issue of ip address changing or power...

Achieve Adequate Network Bandwidth with Bonded T1

Internet service is not one size fits all. Just as businesses vary in type and scope, so do business Internet access requirements. What’s more, bandwidth needs are not static, but grow right along with a company’s size and application needs.

Ever-changing business demands require frequent network design tweaking. The question is, how can your company achieve the perfect level of bandwidth while staying within its budget?

Suppose you’ve already made the leap to T1, but are approaching the limits of T1 service capabilities. An upgrade to T3, which is equivalent to 28 T1 lines at 45 megabits per second (mbps), very possibly would strike you not only as cost prohibitive, but also as bandwidth overkill.

What your company needs is a service middle ground, one that provides the bandwidth you need today with an eye to what you might need in the future. The good news is that there is a way to incrementally...

A speed test is the best way to check the speed and quality of your Internet link. Have you noticed that your files are downloading at a slower speed? Do you feel that the websites you are visiting are starting up too slowly? Check the parameters of your internet connection. With the help of our tester you can now measure:

lag (ping, latency) test – checks the average time to send data packets to various servers simultaneously. Most testers measure only the time it takes to send small data packets (smaller than 500 bytes), but in reality internet browsers and applications usually send and retrieve large data packets, so our tester tests the time it takes to send large packets (about 2–5 kilobytes). The lower the result of the ping the better, which enables more comfortable use of the internet. This parameter is particularly important in online games. download test – checks data downloading speed, which is measured as the total amount of data downloaded...
