Placing multicast proxies on the Internet can largely
reduce the delivery delay of Internet live media streaming using
overlay multicast mechanisms. In this paper, we propose a new
approach to address the issue of proxy placement in an overlay
multicast network. The task is to decide an optimal placement
of multicast proxies in the overlay multicast network so as to
minimize the average end-to-end delay of the overlay skeleton tree
subject to out-degree balancing constraint and maximum delivery
delay bound. We present two heuristic methods for this proxy
placement problem. Experimental results demonstrate that proxy
placement due to our proposed approach can greatly improve the
overlay multicast routing performance. In comparison with an
existing approach commonly used for replica placement in content
distribution networks, our proposed approach significantly
improves the end-to-end latency performance of overlay multicast
networks, and is not much sensitive to network dynamics.
