A Taxonomy of Grouping Semantics and Mechanisms for Real-Time Transport
                         Protocol (RTP) Sources
               draft-ietf-avtext-rtp-grouping-taxonomy-01

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.
