NetFlow is a network protocol widely used to collect metadata about the IP traffic flowing across network devices such as routers, switches and hosts.
NetFlow is a feature that was introduced on Cisco routers to provide the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination of traffic, class of ser...
NetFlow is integrated within the proprietary Cisco IOS installed on the supporting routers and switches by default and works by registering all of the IP traffic that flows in and out of the network through these devices. The information recorded by NetFlow is used for a variety of network ...

Netflow NetFlow is a network protocol developed by Cisco in order to collect and monitor IP network traffic. By utilizing NetFlow, IT teams can analyze traffic flow and determine the traffic source, traffic direction, and how much traffic is being generated. To help you better understand the ...
NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network flow. By analyzing NetFlow data, you can get a picture of network traffic flow and volume. NetFlow is a one-way technology, so when the server responds to the initial client request, ...
NetFlow, introduced by Cisco and adopted by the network device industry at large, today is a widely supported standard used for network monitoring. NetFlow collects IP traffic as it enters or exits an interface, aggregates it into flows based on IP, port, class of service, protocol and source...
View: Netflow formats, configuration, RFC, applications etc. A network flow is a sequence of packets between a given source and destination in one direction only. Cisco routers store and export information about the network flows they handle for network management purposes; high-end routers and sw...
Roland Dobbins, a network engineer in the Internet Services group at Cisco said, “We needed a more granular understanding of how Cisco bandwidth is used,”1. Soon after, Cisco introduced its Netflow Technology in 1996 which allowed for deeper insight, characterization and the ability to further...
Cisco Performance Routing (PfR) is a way of sendingnetwork packetsbased on intelligent path control. Normally, networks use routing protocols to determine the shortest path between an origin and destination. However, the shortest path might be highly trafficked. Instead of picking the shortest path,...
