Due to the recent spread of different styles of watching movies, streaming using Peer-to-Peer (P2P) technology has attracted great attention. In P2P streaming systems, to distribute the network load, since peers from which the user receives data are selected at random, clients have to wait until their desired data are delivered. Therefore, many researches are attempting to reduce the waiting time. However, due to the complexity of implementation, they usually evaluate these methods using machine simulations. In actual environments, interruption time is not always reduced by increasing the number of clients who deliver data. To evaluate the availability of P2P streaming systems, implementing a P2P streaming system is crucial. In this paper, we design and implement a P2P streaming system. With our implemented system, we consider situations in which the proposed system is effective.
