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