In higher traffic networks, the number of flows to be generated can be proportionally adjusted, thus reducing the consumption of resources that are already being expropriated by other functions and services.and services that have been commandeered by other functions and services.Records are a combination of key fields and non-key fields. In FlexibleNetFlow, records are appointed as flow monitors to define the cache used to store flow data. In the Packet ID field of an IP packet, or the Key field as it applies to a flow and a device, there are seven default attributes whose values can be used to determine whether information about a packet sent within the network is unique. Fields such as TCP tag, subnet mask, number of packets, and number of bytes are all key fields. However, these non430 Chapter 11 Network and Host Insight Techniqueskey fields are also captured and exported through NetFlow or IPFIX.Each packet will contain several FlexibleNetFlow keyword fields, and a NetFlow-enabled device forwards thevalues of these fields. The device looks for a set of IP packet attributes for the flow and determines if the packet information is unique. Flexible
