| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Coolstreaming is a mesh based peer-to-peer (P2P) video streaming system in which a source node divides a single video stream into multiple sub-streams. A client-peer node retrieves the sub-streams from multiple parent-peer nodes, combining them into the original video stream. The client-peer node has two buffers, a synchronization buffer and a cache buffer, and arriving data-blocks are synchronized at the synchronization buffer and then forwarded to the cache buffer. In this buffering system, data-block synchronization is important to guarantee video quality. In this paper, we consider the effect of churn on the performance of data-block synchronization scheme with which data-blocks are simultaneously forwarded just after all the data-blocks composing a macro data-block arrive at the synchronization buffer. We assume that data-blocks belonging to a sub-stream arrive at the client-peer node according to an interrupted Poisson process. The synchronization buffer is modeled as a multiple-buffer queueing system with homogeneous interrupted Poisson processes, and the mean forwarding interval is derived. Numerical examples show that the average forwarding interval increases as parent-peer nodes leave more frequently. |
