How does it work?
• The sFlow exporting router monitors traffic traversing it
• The router becomes an Exporter of sFlow data.
• It forwards information to the sFlow Collector
• Collector stores, correlates and presents the information about
• Traffic bottlenecks in networks?
• Applications responsible for bandwidth utilization?
Definitions
NetFlow —NetFlow is a traffic profile monitoring technology
J-Flow —Juniper's implementation of NetFlow.

Collector —Application listening on a UDP port for sFlow datagram.
Exporter —Network element that sends the sFlow datagram.
Conversations — IP communications between two network nodes.
Flow —A flow is a unidirectional stream of packets between two network nodes.
Setup
If they are not already set up to emit flow information, set up devices themselves to emit flow data.
Consult the manuals for your devices for instructions about how to do this.
