Implementation and evaluation of division-based broadcasting system for webcast

Due to the recent popularization of IP multicasts, the continuous broadcasting of audio or video media data is attracting great attention. Although servers can concurrently deliver data to many clients, they have to wait until their data are broadcast. In division-based broadcasting, many researches have proposed scheduling methods to reduce waiting time. A division-based broadcasting system has also been proposed to evaluate these schemes. However, this system does not consider several problems that are assumed in actual networks. In this paper, we implement a division-based broadcasting system for webcasts. In our proposed system, we evaluate the effectiveness of reducing both the waiting and interruption times using conventional methods.
