This memo proposes an extensible Real-time Transport Protocol (RTP)
monitoring framework for extending the RTP Control Protocol (RTCP)
with a new RTCP Extended Reports (XR) block type to report new
metrics regarding media transmission or reception quality.  In this
framework, a new XR block should contain a single metric or a small
number of metrics relevant to a single parameter of interest or
concern, rather than containing a number of metrics that attempt to
provide full coverage of all those parameters of concern to a
specific application.  Applications may then "mix and match" to
create a set of blocks that cover their set of concerns.  Where
possible, a specific block should be designed to be reusable across
more than one application, for example, for all of voice, streaming
audio, and video.  This document is not an Internet Standards Track 
specification; it is published for informational purposes.
