Videoconferencing over an intermediate-proxy

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 delivery solutions for interactive media in the best-effort Internet. A promising approach in satisfying the stringent delay/loss requirements of interactive media transmission is to benefit from configurable proxies. In this study, we introduce an intermediate-proxy solution for videoconferencing applications running over the networks with large delays. By the Internet experiments between the U.S. and Europe, we demonstrate the effectiveness and potential benefits of the proposed approach.
