ABSTRACT
While the recent developments in access technologies such as DSL
and cable enable end-users to communicate with each other in the
means of video and voice, there still exist several hurdles in the
sustainability and reliability of Internet communication services.
In this paper, we focus on improving the performance of the de-
livery solutions for interactive media in the best-effort Internet. A
promising approach in satisfying the stringent delay/loss require-
ments of interactive media transmission is to benefit from config-
urable proxies. In this study, we introduce an intermediate-proxy
solution for videoconferencing applications running over the net-
works with large delays. By the Internet experiments between the
U.S. and Europe, we demonstrate the effectiveness and potential
benefits of the proposed approach.
