sFlow vs NetFlow: What's the Difference?
In any given network, switches, routers, and firewalls may support different flow protocols. After all, there’s NetFlow, sFlow, IPFIX, and J-Flow, to name a few. With so many options, you may be wondering “Which flow protocol should I use?” It’s a common question, and it has a relatively simple answer: While some devices support multiple protocols, a device typically only supports one type of flow protocol, so you should use the protocol your device and collector supports.
