NetFlow is often used for flow data analytics. It tracks and records all traffic as it enters and exits an interface. NetFlow was created by Cisco and is the most commonly used flow technology. It also helps you weed out performance and security issues within the network by analyzing network device traffic (i.e., traffic through routers, switches, firewalls, and servers).īenefits of using network traffic monitoring:

Monitoring network traffic provides improved visibility and invaluable insights that are highly beneficial to understanding your network's behavior.

Network traffic monitoring is the process of analyzing the traffic that flows across a network by keeping track of its source its destination and the applications, ports, and protocols involved in the conversation.

Busy/heavy traffic: Traffic that consumes a high amount of bandwidth.

Non-real-time traffic: Traffic consumed by an application for day-to-day activities.

Real-time traffic: Traffic that is time-sensitive and requires high-quality data transmission.

During data transmission, traffic data from the source gets divided into individual packets and is reassembled at the destination later. The data transferred is comprised of packets, which are the fundamental units of network data transfers. Network traffic is the total data moving through a network from a source to a destination at a given point in time.
