Why flow-based network traffic bandwidth monitoring?

Flow-based monitoring exports flows from routers, switches and firewalls to collect information about traffic that is traversing in the network. Supporting various flows in market such as NetFlow, sFlow, jFlow, IPFIX, Appflow, NetStream etc., NetFlow Analyzer analyzes traffic that flows through the network and highlights any unexpected or anomalous traffic, or excess bandwidth usage.

Benefits of flow monitoring over others:

  • Analyze traffic usage by applications, users, protocols and QoS.
  • Faster troubleshooting with conversation level details.
  • Provides real-time diagnostics with up to one-minute granularity.
  • Requires less data storage as compared to other monitoring techniques.
  • Provides accurate information on bandwidth utilization to make critical decisions.
  • Supports advanced technologies like NBAR that gives payload info within packets for analysis.
  • Detects network security threats.
