We describe a portable and robust software mechanism for adaptive
frame rate control for real time packet video transfer and viewing in
workstation environments. No special hardware or system support is
assumed. Our contributions include (1) a responsive feedback system
for dynamic presentation layer rate control in response to network
load, (2) a simple and effective transport layer flow control scheme
built upon an unreliable network protocol, and (3) data structures and
scheduling support for integrating the rate and flow control
mechanisms. We demonstrate that excellent jitter control is achieved
by gracefully trading image resolution, and loss rates can be
drastically reduced by appropriate flow control.
