This paper proposes P2P live-streaming system suitable for private distribution. This system constructs distribution network considering transmission bandwidth of each node. In particular, the system carefully selects a certain number of broadband nodes and set them around the distributor’s node in P2P network. A set of the selected broadband nodes plays a role of virtual distributor with large amount of transmission bandwidth and provides contents to peers instead of origin. The original contribution of our proposed system includes double mesh P2P network structure for scalable and efficient private live-streaming services, and its detailed design description. In this system, network bandwidth is used effectively. As a result, the private distribution can be provided with higher scalability. With extended simulation experiments, we confirmed that the proposed system presents about half load of distributor compared with the existing system.
