What is netflow traffic

Interested in knowing more? Get in touch with our experts to learn about NetFlow Analyzer's capabilities. Register for a free, personalized demo now! SNMP is one of the oldest and most efficient protocols for bandwidth monitoring. While SNMP is the most relevant option for real-time monitoring, only NetFlow can give you information on what your network is being used for and by whom.

NetFlow is appropriate for complex networks with high traffic as well as anomaly detection. NetFlow Analyzer, our flow-based network management software, integrates NetFlow, sFlow , jFlow , IPFIX, and various other flow formats to provide real-time visibility into network traffic and bandwidth performance.

NetFlow Analyzer helps you diagnose and troubleshoot network slowdown and anomalies—as well as plan your future bandwidth needs—with its detailed reports. Download a free trial of our real-time NetFlow analysis tool now! Investigate the root cause of network issues with QoS related reports and optimize your network performance. Set pre-defined threshold settings based on utilization, duration and frequency to effectively monitor your network.

Monitor critical factors affecting VoIP, Video performance and ensure best-class service levels. NetFlow is widely used for collecting and analyzing network flow data statistics. If we collect NetFlow records from all NetFlow-enabled network devices — routers, switches, etc.

These data points can be used for anomaly detection, monitoring bandwidth usage, capacity planning, and to validate the effectiveness of QoS policy. The first NetFlow version 1 was supported in all the initial NetFlow releases.

Versions 2, 3, and 4 were only usable as internal releases. NetFlow v5 is the most commonly used version because it has a fixed packet format and is still supported by various routers.

Versions 7 and 8 had a few improvements and they are no longer in practice. Meanwhile, NetFlow version 9 is simplified since this version has FNF capabilities enabled and incorporates a dynamic packet format. Nine versions later, NetFlow still gains popularity not only due to its performance in network management, but also as a significant component of security operations.

The primary output of all these NetFlow versions is a flow record. Flow data from multiple devices can also be grouped as per their business functions, thereby generating business-oriented reports. Software Whatsup Gold. SNMP is great for monitoring networked devices and capacity planning, but it lacks in more granular and in-depth traffic and bandwidth usage and utilization. For additional Reading on What Netflow is and How you can use it to monitor and analyze your Network , check out the following Whitepapers for more in-depth reading:.

An Ip Flow is made up of a Set of 5 attributes and can have up to 7 total. History of Netflow As mentioned previously, Netflow was conceived at Cisco Systems, and is now a major standard that is included in almost every business grade router and switch that Cisco and other manufacturers produced.
