Abstract Abstract
There is an ongoing effort in IETF RMCAT working group to standardize The Real-time Transport Protocol (RTP) is used for interactive
rate adaptation algorithm(s) for real-time interactive communication. multimedia communication applications. These applications are
To ensure seamless and robust user experience, the proposed rate typically required to implement congestion control. To ensure
adaptation algorithm(s) should work well across all access network seamless and robust user experience, a well-designed RTP-based
types. This document describes test cases for evaluating congestion control algorithm should work well across all access
performances of the proposed rate adaptation solutions over LTE and network types. This document describes test cases for evaluating

Sandlund for their valuable comments while writing this draft.
7. IANA Considerations 7. Security Considerations
This memo includes no request to IANA. The security considerations in [I-D.ietf-rmcat-eval-criteria] and the
relevant congestion control algorithms apply. The principles for
congestion control are described in [RFC2914], and in particular any
new method MUST implement safeguards to avoid congestion collapse of
the Internet.
8. Security Considerations The evaluation of the test cases are intended to be run in a
controlled lab environment. Hence, the applications, simulators and
network nodes ought to be well-behaved and should not impact the
desired results. It is important to take appropriate caution to
avoid leaking non-responsive traffic from unproven congestion
avoidance techniques onto the open Internet.
Security issues have not been discussed in this memo. 8. Acknowledgements
