Rate control on correlation coefficient of network delay

The demand to access multimedia data such as live video is increasing due to the spread of broadband access network. However, the Internet only provides so called best-effort service. The network condition of the Internet shows fluctuation. Delivering video without any control causes degradation of the final video quality. In this paper we propose a stream-rate control algorithm RC³ that uses correlation of network delay to evaluate available bandwidth. We show performance of RC³ derived from simulations.
