Due to the recent prevalence of the Internet, broadcasting continuous media data, e.g., audio and video, on the IP (Internet protocol) networks has attracted great attention. In broadcasting systems, generally, a server broadcasts the same data repetitively. Although the server can deliver the data to many clients concurrently, clients have to wait until their desired data are broadcast. To reduce the waiting time, several researches employ a division based broadcasting system, which reduces the waiting time by dividing the data into several segments and broadcasting precedent segments frequently. These researches often assume that there are many clients and broadcasting delivery is more effective than client-server delivery. However, these researches do not show its concrete availability. In this paper, by designing and implementing a division based broadcasting system called "d-Cast", we discuss the availability for division based broadcasting systems.
