PRTG makes LAN bandwidth management easy

Custom alerts and data visualization make it easy to monitor, identify, and prevent network congestion issues









Cure your network congestion nightmares

Sure, you can worry about whether your data flows efficiently from point to point, if important information is getting through security, or what might happen if network issues become user issues. Or, you can kick back on the beach and enjoy knowing Paessler PRTG is your bandwidth management software.

bandwidth hogs

Bandwidth hogs are those greedy devices on your network that use more bandwidth than they should, slowing down other users. PRTG helps you locate these hogs and manage or limit their bandwidth usage.

This reduces congestion, allowing for faster network speed and fair use for other devices and people on the network.

Monitor bandwidth over the long run

Long-term monitoring often provides for new and interesting findings. PRTG provides a wealth of historical data that gives exponential decision-making power, answering important questions that allow you to appropriately upgrade or expand your network.

Identify peak hours and learn which devices use the most bandwidth to design a more effective network.

Track different
traffic types

Analyze the different types of network traffic so you can manage your bandwidth usage more effectively. VoIP, web browsing, file transfers, and more use network resources at different levels.

Filter data traffic according to IP addresses, protocols, data types, ports, and more, and make sure your traffic is flowing correctly with PRTG.


Limit bandwidth based on specific needs

Some tasks and devices don’t need as much bandwidth as others, so PRTG lets you identify where you can limit bandwidth based on needs. For example, you can limit bandwidth for backups so they don’t take as much.

You can also allocate bandwidth on a router-to-router basis or in switches, or restrict LAN bandwidth by specifying which traffic has priority on the devices connected to your LAN.


Customize your
alert levels

Only receive alerts when they’re absolutely necessary, customized by you to meet your particular needs. You know your network best, so PRTG lets you customize your alerts based on the warning and error thresholds you set.

You can also set the seriousness of the alert and the people to be notified when an alert is triggered.








What bandwidth management looks like in PRTG

Diagnose network issues by continuously monitoring your device’s bandwidth consumption. Show network usage and traffic patterns in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot network congestion.


Start managing your bandwidth with PRTG and see how it can make your network more reliable and your job easier.

Manage bandwidth: FAQ


1. What is bandwidth management?

Bandwidth management is an important part of network administration. It makes sure that important applications and devices have the bandwidth they need to operate. It allows informed allocation of network resources, helps you manage your network traffic better, and keeps your network more secure.

2. Can I improve my network speed with bandwidth management?

Yes. Bandwidth management provides a range of management capabilities that positively affect speed. For example, by managing bandwidth allocation, you can reduce network congestion, which has the benefit of improving your network speed.

3. What’s the difference between bandwidth monitoring, bandwidth management, and bandwidth controlling?

With bandwidth monitoring, you won’t yet be actively managing your bandwidth. Instead, you'll simply observe the amount of bandwidth that is consumed by your network’s devices and applications and then make a decision on how best to manage your bandwidth.

Active bandwidth management includes the distribution of bandwidth to the devices in your network. A variety of bandwidth management tools are available to help you manage bandwidth. You can also adjust the individual bandwidth consumption of devices in the respective device’s settings.

Bandwidth controlling is usually used synonymously with bandwidth management. You can use it to measure, check, limit, and customize the distribution of your bandwidth and data rates at any time.

With PRTG, you can control your data rate and test bandwidth. You cannot, however, prioritize traffic. If you wish to prioritize traffic, think about picking up a separate bandwidth controller tool.

4. Can PRTG monitor real-time bandwidth usage?

Yes. PRTG is an all-in-one monitoring solution. Through various sensors, PRTG can track the data passing through your network in real time.

5. Does PRTG reduce network costs?

Absolutely! Studies have shown that PRTG can help lower network costs in several ways. Being able to optimize your network helps reduce the cost of bandwidth upgrades. Another way is through resource allocation. Appropriately allocating network resources makes your network perform better, saving costs on network failures or service interruptions.

6. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
