1. Introduction
The IP Flow Information Export (IPFIX) Information Model [RFC7012]
provides a set of abstract data types (ADTs) for the IANA "IPFIX
Information Elements" registry [IANA-IPFIX], which contains a rich
set of Information Elements for description of information about
network entities and network traffic data, and abstract data types
for these Information Elements. The IPFIX Protocol Specification
[RFC7011], in turn, defines a big-endian binary encoding for these
abstract data types suitable for use with the IPFIX protocol.
However, present and future operations and management protocols and
applications may use textual encodings, and generic framing and
structure, as in JSON [RFC7159] or XML. A definition of canonical
textual encodings for the IPFIX abstract data types would allow this
set of Information Elements to be used for such applications and for
these applications to interoperate with IPFIX applications at the
Information Element definition level.
Note that templating or other mechanisms used for data description
for such applications and protocols are application specific and,
therefore, out of scope for this document: only Information Element
identification and value representation are defined here.
