Internet Engineering Task Force (IETF) B. Claise Request for Comments: 6313 G. Dhandapani Updates: 5102 P. Aitken Category: Standards Track S. Yates ISSN: 2070-1721 Cisco Systems, Inc. July 2011 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. Status of This Memo This is an Internet Standards Track document.
