Abstract

   There is an ongoing effort in IETF RMCAT working group to standardize
   rate adaptation algorithm(s) for real-time interactive communication.
   To ensure seamless and robust user experience, the proposed rate
   adaptation algorithm(s) should work well across all access network
   types.  This document describes test cases for evaluating
   performances of the proposed rate adaptation solutions over LTE and
   Wi-Fi networks.
