Initially, this approach was primarily used for capacity analysis to understand the sources and volumes of traffic. Over time, its scope has broadened to include deep packet inspection for firewalls and traffic anomaly analysis for intrusion detection systems. Here are some top network traffic analysis tools: <ul style=";font-family:Arial;"> <li style="font-size: 18px; ;font-family:Arial;"> ManageEngine NetFlow Analyzer (Editor’s Choice) : This tool supports various flow protocols like NetFlow, IPFIX, sFlow, and J-Flow, extracting data from switches and routers. It is available on Windows Server, Linux, and AWS, and offers a 30-day free trial. </li> <li style="font-size: 18px; ;font-family:Arial;"> ManageEngine OpManager Plus : An enhanced version of the standard OpManager network performance monitor, it includes traffic analysis.

It runs on Linux. </li> <li style="font-size: 18px; ;font-family:Arial;"> SolarWinds NetFlow Traffic Analyzer : A leading tool that works with NetFlow, J-Flow, sFlow, NetStream, and IPFIX for packet capture. </li> <li style="font-size: 18px; ;font-family:Arial;"> Elastic Stack : A comprehensive suite of data capture and analysis tools, featuring Elasticsearch and Kibana. </li> <li style="font-size: 18px; ;font-family:Arial;"> Plixer One : A security-focused traffic analyzer that samples traffic from multiple network locations simultaneously. </li> <li style="font-size: 18px; ;font-family:Arial;"> Open WIPS-ng : A wireless network protection system that incorporates traffic analysis. </li></ul> At the basic level, packet sniffers copy passing traffic into files, which then need to be processed to gain meaningful insights into traffic patterns. On the more advanced side, complex systems sample traffic from several points in the network simultaneously, consolidating the data to detect unusual user behavior. While the network provides live data, network traffic analysis tools rarely operate in real-time . They typically wait until a series of packets have been captured and stored before processing. This means NTAs function at the application layer rather than the network layer, providing a better overview of network activity. The information at the network layer is often insufficient for identifying overall traffic patterns and detecting malicious activities that are spread across multiple packets or involve actions from different sources. Network traffic analysis can offer rapid feedback, but it is generally "nearly live" rather than real-time. Security applications require streams of data to detect threats, and for capacity planning, accuracy in projections is more important than immediacy.
