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