How to test the performance of RAT?
To evaluate the conformance of RAT to the RTP spec you may use crtpdump or rtpdump (part of Henning Schulzrinne’s rtptools package) to observe the behaviour. To evaluate the loss mitigation functions of RAT it should be run against a packet reflector that can add jitter, loss, and packet duplication. The source code for the application we use for this can be found here.
