               A Taxonomy of Semantics and Mechanisms for
               Real-Time Transport Protocol (RTP) Sources

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 properties and
   relationships among RTP sources and defines common terminology for
   discussing protocol entities and their relationships.
