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, J-flow, IPFIX, Appflow, NetStream etc., NetFlow Analyzer analyzes the complete traffic that passes across the network and highlights any unexpected traffic or excess data volume.

Benefits of flow monitoring over others:

  • Details traffic usage by applications, users, protocols and QoS.
  • Faster troubleshooting with conversation level details.
  • Provides real-time diagnostics up to 1 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 NBAR2 that gives payload info within packets for analysis.
  • Detects threats for network security.
