This document describes two reference video traffic models for
evaluating RTP congestion control algorithms.  The first model
statistically characterizes the behavior of a live video encoder in
response to changing requests on the target video rate.  The second
model is trace-driven and emulates the output of actual encoded video
frame sizes from a high-resolution test sequence.  Both models are
designed to strike a balance between simplicity, repeatability, and
authenticity in modeling the interactions between a live video
traffic source and the congestion control module.  Finally, the
document describes how both approaches can be combined into a hybrid
