Control Network Traffic

Network Traffic Management - The Easy Way

How Does PRTG Help You to Control Network Traffic?

PRTG uses SNMP, packet sniffing, and NetFlow to measure network traffic. SNMP, the most basic method, allows you to watch the total traffic flowing through your network and to classify it by port (port monitoring). For a more detailed network traffic classification, you can use packet sniffing or NetFlow / sFlow: these methods also enable you to watch network traffic broken down by IP address or protocol, and to generate toplists.

More than 500,000 administrators rely on PRTG Network Monitor every day - to control network traffic, monitor servers, and improve network performance.

Benefits of Network Traffic Control

This way, you can see what is using your Ethernet bandwidth, e.g. Internet surfing, VoIP traffic, ftp downloads, etc. This helps you to exercise effective network traffic control: you will be able to detect possible network bottlenecks at an early stage, turn off applications that use a lot of bandwidth traffic when you need the resources for other applications, limit the bandwidth available for each PC, etc. Controlling network traffic will also show you when you should buy additional bandwidth, or whether your current resources will be sufficient when you are planning to deploy new systems, for example VoIP telephony.
