     Evaluating Congestion Control for Interactive Real-time Media
                   draft-ietf-rmcat-eval-criteria-06

Abstract

   The Real-time Transport Protocol (RTP) is used to transmit media in
   telephony and video conferencing applications.  This document
   describes the guidelines to evaluate new congestion control
   algorithms for interactive point-to-point real-time media.
