heal.abstract	In this manuscript, we contribute measurement and modeling results for H.264 encoded videoconference traffic. The analysis of the frame-size autocorrelation function of extensive video data that were gathered during realistic experiments with two popular videoconference terminals (currently the only supporting the H.264 encoder) suggested that H.264 videoconference traffic is fully uncorrelated as a consequence of the constrained (in the loop) operation mode of the encoders. By using this fact and by statistically analyzing the sampled frame-size histogram, we conclude that H.264 traffic can be reasonably represented by a D/G/∞ queue with deterministic arrivals according to the video frame rate and service times that can be fitted by a histogram-based model proposed on a previous study. © 2006 IEEE.	en
