| Network flow is defined as a unidirectional sequence of packets between given sourceand destination endpoints. Network flows are highly granular: flow endpoints areidentified both by IP address as well as by transport layer application port numbers.(NetFlow also uses IP Protocol, ToS,and the input interface port to uniquely identifyflows.) Conventional network layer switching handles incoming packetsindependently, with separate serial tasks for switching, security, services, and trafficmeasurements applied to each packet. With NetFlow switching, this process isapplied only to the first packet of a flow. Information from the first packet is used tobuild an entry in the NetFlow cache. Subsequent packets in the flow are handled viaa single streamlined task that handles switching, services, and data collectionconcurrently. |
