Now that we have examined the two flow monitoring protocols in detail, the burning question on the lips of many network admins is: Which protocol is better? Which one should I use? Well, there is really no definite answer. Traffic flows can either be passively monitored by an offline router or switch or actively monitored by a router participating in the network. It answers the questions of "who is using my bandwidth and what are they doing with it?" NetFlow can't tell you about things like application performance, response time, errors, jitter, and packet loss. This will serve as the basis for the NetFlow template used in the export process. NetFlow Traffic Analyzer (NTA) is also available in a standalone module. Sources that include packet data by connecting to a SPAN port or a network TAP are considered internal sources. sFlow: A Technical Review Utilization Measurements The above configuration displayed traffic rates of the same live traffic using NetFlow and sFlow With sFlow, users can quickly detect abnormal flows and locate the source of attack traffic.
