Evaluation of P2P streaming systems for webcast

Abstract

Due to the recent spread of streaming delivery of movies, streaming using Peer-to-Peer (P2P) streaming technology has attracted much attention. In P2P streaming systems, to distribute the network load, peers from which the user receives data is selected at random. For this, clients have to wait until their desired data is delivered. Therefore, there are many researches to reduce the waiting time. However, because of the complexity of the implementation, they usually evaluate these methods using computer simulations. In actual environment, indeed, interruption time is not always reduced by increasing clients to deliver data. To evaluate the effectiveness of P2P streaming systems, it is important to implement an actual P2P streaming system. In this paper, we evaluate a P2P streaming system. By using our implemented P2P streaming system, we investigate situations that its system is effective. As a result of our evaluation, we confirmed that interruption time is reduced effectively.
