While collecting the interface counters every five minutes has proven to be useful in the past, more and more granular information is required from network elements for a series of applications: performance assurance, capacity planning, security, billing, or simply monitoring. However, the amount of information has become so large that, when dealing with highly granular information such as Flow information, a push mechanism (as opposed to a pull mechanism, such as Simple Network Management Protocol (SNMP)) is the only solution for routers whose primary function is to route packets. Indeed, polling short-lived Flows via SNMP is not an option: high-end routers can support hundreds of thousands of Flows simultaneously. Furthermore, in order to reduce the export bandwidth requirements, the network elements have to integrate mediation functions to aggregate the collected information, both in space (typically, from different linecards or different Exporters) and in time.

     Export of Structured Data in IP Flow Information Export (IPFIX)


   This document specifies an extension to the IP Flow Information    Export (IPFIX) protocol specification in RFC 5101 and the IPFIX    information model specified in RFC 5102 to support hierarchical    structured data and lists (sequences) of Information Elements in data    records.  This extension allows definition of complex data structures    such as variable-length lists and specification of hierarchical    containment relationships between Templates.  Finally, the semantics    are provided in order to express the relationship among multiple list    elements in a structured data record.
