The existing taxonomy of sources in the Real-time Transport Protocol (RTP) [RFC3550] has previously been regarded as confusing and inconsistent. Consequently, a deep understanding of how the different terms relate to each other becomes a real challenge. Frequently cited examples of this confusion are (1) how different protocols that make use of RTP use the same terms to signify different things and (2) how the complexities addressed at one layer are often glossed over or ignored at another.

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


   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.
