Overview of sFlow
Definition
Sampled Flow (sFlow) is a traffic monitoring technology that collects and analyzes traffic statistics.
Purpose
Enterprise networks differ from carrier networks in that they are smaller, more flexible, and more likely to be attacked. Due to these characteristics, enterprise networks have problems with service exceptions. Enterprise users require a traffic monitoring technique on interfaces of devices to locate unexpected traffic and the source of attack traffic in a timely manner so that they can quickly rectify faults to ensure stable running of the network.
sFlow is developed to achieve the preceding purpose. sFlow provides interface-based traffic analysis, facilitating preventive maintenance on enterprise networks.
