Avoid these problems with PRTG’s network traffic management
Network traffic management with Paessler PRTG uses network monitoring tools and in-depth bandwidth monitoring and network traffic analysis to ensure the continuous optimization of your network operations. Maximize the performance and security of existing networks, and identify network-intensive activities that can be incorporated into network planning and growth strategies.
Insufficient network performance
Monitor network devices such as routers, switches, or firewalls that are not configured properly, as well as application performance, which can quickly compromise your entire network.
This usually results in slow data transmission or network resources being no longer accessible. PRTG helps prevent downtime and enhance end-user experience.
Impairment of Internet access
Prevent poor network performance, which not only affects data traffic within a network, but also the access to resources on the Internet.
In fact, this can cause cloud-based applications to react very slowly or to be no longer accessible. Use PRTG to ensure uninterrupted Internet access and maximum productivity.
Disruptions of communication
Avoid problems in the local network of your company – and possibly remote locations linked through your WAN which can also be impacted.
It helps you avoid loss of access to centrally stored data or databases and collaboration platforms. This helps ensure the smooth workflow of employees who work on the road or in their home office.
What traffic monitoring looks like in PRTG
Diagnose network issues by continuously tracking traffic flows in your IT infrastructure. Show bandwidth usage, latency, VoIP and quality of service (QoS) stats, unusual traffic patterns, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot network congestion and other performance issues.
Start monitoring & managing network traffic with PRTG and see how it can make your network more reliable and your job easier.
Easy as 1-2-3: Manage your network traffic with PRTG
Monitor your entire network
By monitoring your network and its individual devices, you can quickly get an overview of the data traffic and also analyze it in more detail, as required.
Break traffic down, for example, by IP address, port, and protocol to get the insights you need. To do so, PRTG uses common technologies such as SNMP, flow (NetFlow, jFlow, sFlow, IPFIX), or packet sniffing.
Create reports to gain an overview
PRTG also provides you with reports according to your needs. This allows you to view and analyze your network traffic over a longer period of time.
This is especially helpful when there is a high volume of data traffic outside of working hours that would otherwise have gone unnoticed.
Manage your network traffic
PRTG helps you make better, more informed decisions with data generated by the sensors and analyzed reports.
For example, if increased traffic occurs at certain times, you can now define the cause and take appropriate action. This also empowers you to make better long-term resource planning decisions.

Managing network traffic: FAQ
What is network traffic management?
Network traffic management refers to the techniques, processes, and tools used to monitor, control, and optimize the flow of data across a network. Its goal is to ensure efficient data transmission, prevent congestion, maintain security, and provide a high quality of service (QoS) for all users and critical applications.
Key aspects of network traffic management include:
- Traffic monitoring: Network traffic is continuously monitored to detect patterns, usage levels, and potential bottlenecks. Tools like packet sniffers or flow analyzers collect data on the volume and type of traffic, sources, destinations, and performance metrics.
- Traffic classification: Identifies different types of traffic (e.g., video streaming, web browsing, email) to apply appropriate rules for managing their flow.
- Traffic shaping: Controls the rate at which data is sent across the network to avoid congestion. This technique smooths out bursts of traffic to ensure steady transmission.
- Prioritization (QoS): Some types of data, like voice or video, are given higher priority over others like file downloads to ensure real-time applications run smoothly.
- Load balancing: Distributes traffic evenly across multiple servers or network paths to avoid overloading a single resource.
- Rate limiting: Restricts the amount of bandwidth certain users or applications can consume, preventing them from hogging network resources.
What are the benefits of network traffic management?
Network traffic management offers several key benefits that help improve the performance, security, and reliability of a network. These benefits are crucial for businesses, service providers, and individuals who rely on stable and efficient network connectivity.
- Reduced congestion: By controlling and distributing traffic loads effectively, network traffic management prevents network congestion, allowing for smoother data flow and faster response times.
- Optimized bandwidth usage: Ensures that available bandwidth is used efficiently, preventing overuse by a single user or application and allowing more traffic to pass through without performance degradation.
- Prioritization of critical applications: Network traffic management allows administrators to prioritize important applications (like video conferencing, voice calls, or business-critical apps) over less critical traffic, ensuring smooth operation even during periods of high demand.
- Enhanced network security: Continuous monitoring of traffic patterns helps detect abnormal or malicious activities (such as Distributed Denial of Service (DDoS) attacks or data breaches), enabling rapid responses.
- Traffic filtering: Firewalls, intrusion detection/prevention systems, and deep packet inspection (DPI) can block harmful traffic before it reaches the network or causes damage.
- Preventing bandwidth abuse: Limiting bandwidth for certain users or applications prevents intentional or accidental overuse, which can weaken the overall security of the network.
Can PRTG manage network traffic?
PRTG is no classic network traffic management tool. However, it can support you with in-depth network traffic monitoring and traffic classification so that you have the data you need to implement informed traffic shaping, rate limiting, and prioritization.
Which protocols does PRTG use for network traffic monitoring and management?
PRTG uses common protocols and technologies such as SNMP (Simple Network Management Protocol), flow (NetFlow v5 and v9, jFlow, sFlow, IPFIX), and packet sniffing to analyze network traffic and identify the top talkers in a network.
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.
