Best Bandwidth Limiter Tools

Traffic management requires some tough choices when the solution of just buying-in extra equipment to expand capacity is not available. There are a number of cost-free measures you can take to find extra capacity. For example, traffic shaping measures, such as queuing can really help improve the response times of time-sensitive applications.

Examining traffic patterns can identify underutilized resources that could be moved to increase capacity on busy links.

When your topology and sub domains are optimized, you will probably find that traffic just increases and uses up all of the spare capacity you squeezed out of the network. Some business activities and applications just generate a lot of traffic and will continue to gobble up all available capacity.

Here is our list of the best bandwidth limiter & controller tools:

NetLimiter is a bandwidth throttling tool that enables the user to allow or block applications and control the amount of bandwidth they’re allowed to use. NetLimiter comes with three tools that let you control network traffic: Limits, Priorities, and Blocker. Limits enable you to set a maximum bandwidth transfer speed limit for an application.

Key features:

  • Control application bandwidth usage
  • Block applications
  • Prioritize traffic
  • Customizable filters

Why do we recommend it?

NetLimiter is probably the closest service for this following the title of this article because it doesn’t just prioritize traffic – which limits capacity to non-prioritized applications – but it actually enables you to throttle specific types of traffic. With this system, you can block or slow down specific application traffic and also hold up some traffic while letting others straight through your network devices.

The Priorities tool allows you to pick which application traffic has priority. NetLimiter has an internal priority engine, which automatically restricts other applications when a high priority application is in use. There are four priority levels that can be assigned: Critical, High, Normal, and Low.

Blocker allows you to block particular applications such as non-work services to minimize distractions. All of these tools can be customized with filters with the Filter Editor. Here you can filter applications by a full path, part of the path, localhost/loopback traffic, local IP address, destination IP address, local port numbers, remote port numbers, and more.

Who is it recommended for?

This on-premises software is a great system for businesses that want to discourage certain types of user activity as well as manage traffic through queuing and prioritizing. The tool can be used to substitute for firewall rules to completely block some traffic. The software is only available for Windows and Windows Server.

Bandwidth Limiter & Controller  FAQs

What does bandwidth control do?

Bandwidth control allows you to restrict the amount of network capacity that is generated by a piece of software or handled by a piece of hardware. This is useful for businesses that do not have enough budget to provide the maximum required network bandwidth for all of its software and needs to prevent one application from overwhelming the system.

Does QoS slow down the internet?

The capacity of your internet gateway is finite. You can only slow it down by reducing the capacity of your gateway interface or lowering the bandwidth of your internet service plan. QoS gives priority to certain applications – usually interactive services such as streaming video or VoIP. The overall capacity of the internet connection remains the same, but some services get slowed to favor others.

How do I disable a bandwidth limiter on my network?

All bandwidth limiters can be turned off. However, where you go to remove the restriction depends on where the limiter is operating. If you didn’t activate the limit, you will need to analyze the traffic on your network to detect whether the limit is imposed within a piece of software, in an operating system, or on a network device.

Can I limit my network bandwidth manually?

Network bandwidth relies on the capacity of the cables and devices that serve it. Downgrading any piece of hardware will lower network bandwidth. However, this will more likely result in packet loss. Limit bandwidth for a particular function is to use the options within the software you want to limit or within the operating system of the device that you want to restrict.
