Abstract

   It is evident that to ensure seamless and robust user experience
   across all type of access networks multimedia communication suits
   should adapt to the changing network conditions.  There is an ongoing
   effort in IETF RMCAT working group to standardize rate adaptive
   algorithm(s) to be used in the real-time interactive communication.
   In this document test cases are described to evaluate the
   performances of the proposed endpoint adaptation solutions in LTE
   networks and Wi-Fi networks.  The proposed algorithms should be
   evaluated using the test cases defined in this document to select
   most optimal solutions.
