Abstract:
This document describes a protocol independent encoding for flow
characteristics (a.k.a. metadata). A flow is defined as a set of IP
packets passing through a network in a given direction. All packets
belonging to a particular flow have a set of common properties (e.g.
IP, port, transport). Flow metadata exposes key characteristics of
the flow such as the originating application, the type of media in
use (e.g. audio, video) and others as defined in
[I-D.eckert-intarea-flow-metadata-framework]. The flow
characteristics are expressed in terms of information elements.
These information elements are signaled either out of band or in band
but always along the same path of the flow associated with the
application.
[I-D.eckert-intarea-flow-metadata-framework] defines the overall
framework for flow metadata and the definition of the flow
characteristics, whereas this document captures the encoding of these
characteristics. The mapping of flow metadata encoding to different
signaling protocols is outside the scope of this document.
