Here is an updated version of the video-traffic-model draft. 

The main changes are in Sec. 5, where we've updated the statistical models of both transient and steady-state behaviors based on the collection of empirical data presented during the Interim meeting (see slides at

In addition, this revision contains some editorial changes and notational clean-ups throughout. 

As always, review comments are welcome as we consider this work to be fairly mature at this stage.

   This document describes two reference video traffic source models for
   evaluating RMCAT candidate algorithms.  The first model statistically
   characterizes the behavior of a live video encoder in response to
   changing requests on target video rate.  The second model is trace-
   driven, and emulates the encoder output by scaling the pre-encoded
   video frame sizes from a widely used video test sequence.  Both
   models are designed to strike a balance between simplicity,
   repeatability, and authenticity in modeling the interactions between
   a video traffic source and the congestion control module.
