A Taxonomy of Grouping Semantics and Mechanisms for Real-Time Transport
Protocol (RTP) Sources
draft-ietf-avtext-rtp-grouping-taxonomy-04
Abstract
The terminology about, and associations among, Real-Time Transport
Protocol (RTP) sources can be complex and somewhat opaque. This
document describes a number of existing and proposed relationships
among RTP sources, and attempts to define common terminology for
discussing protocol entities and their relationships.
