The assembly of packet data into Flows serves a variety of different purposes, as noted in the requirements [RFC3917] and applicability statement [RFC5472] for the IP Flow Information Export (IPFIX) protocol [RFC7011]. Aggregation beyond the Flow level, into records representing multiple Flows, is a common analysis and data reduction technique as well, with applicability to large-scale network data analysis, archiving, and inter-organization exchange. This applicability in large-scale situations, in particular, led to the inclusion of aggregation as part of the IPFIX Mediation Problem Statement [RFC5982], and the definition of an Intermediate Aggregation Process in the Mediator framework [RFC6183].

Flow Aggregation for the IP Flow Information Export (IPFIX) Protocol
This document provides a common implementation-independent basis for the interoperable application of the IP Flow Information Export (IPFIX) protocol to the handling of Aggregated Flows, which are IPFIX Flows representing packets from multiple Original Flows sharing some set of common properties. It does this through a detailed terminology and a descriptive Intermediate Aggregation Process architecture, including a specification of methods for Original Flow counting and counter distribution across intervals.
