Abstract

   The Real-time Transport Protocol (RTP) is a common transport choice
   for interactive multimedia communication applications.  The
   performance of such applications typically depends on a well-
   functioning congestion control algorithm.  To ensure seamless and
   robust user experience, a well-designed RTP-based congestion control
   algorithm should work well across all access network types.  This
   document describes test cases for evaluating performances of such
   congestion control algorithms over LTE and Wi-Fi networks.
