sFlow Monitoring
sFlow (sampled folw) is a real-time packet sampling method. sflow analyzes end-to-end
and network flow traffic characteristics in Ethernet network, as well as collects MIB infor-
mation to monitor the device.
In other words, in order to process the Flow by hardware, it operates only by sampling
method in consideration of a lot of data amount and processing overhead. This device
operates traffic monitoring via sflow without network degradation.
