How does sFlow compare to other traffic monitoring technologies?
Cisco Netflow® was originally developed as a technique to accelerate IP routing. One feature of Netflow that became popular was its ability to report on expired TCP/IP flows. Unlike Netflow, sFlow was developed exclusively as a monitoring technology. sFlow offers greater scalability and reporting detail; providing detailed, real-time, L2-7 information on traffic throughout the network.
RMON was developed in 1991 to standardize probes that could be attached to shared networks. RMON doesn't scale well in today's high-speed, segmented networks. Most network equipment vendors now implement sFlow, providing greater detail and scalability at a much lower cost.
