sFlow
sFlow is the standard for monitoring high-speed switched and routed networks. sFlow
technology is built into network equipment and gives complete visibility into network activity,
enabling effective management and control of network resources.
technology is built into network equipment and gives complete visibility into network activity,
enabling effective management and control of network resources.
The sFlow monitoring system consists of an sFlow agent (embedded in a switch or router or
in a standalone probe) and a central sFlow collector. The sFlow agent uses sampling
technology to capture traffic statistics from the device it is monitoring. The sFlow datagrams
are used to immediately forward the sampled traffic statistics to an sFlow collector for
analysis.

The sFlow agent uses two forms of sampling: statistical packet-based sampling of switched
