sFlow 
sFlow (RFC3176) is a technology for monitoring traffic in data networks containing switches and routers. 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 architecture and sampling techniques used in the sFlow monitoring system were 
designed for providing continuous site-wide (and enterprise-wide) traffic monitoring of high speed switched and 
routed networks.
