Video production sites use general file servers to exchange their video data via high-speed networks. However, these servers doesn't have enough performance to smoothly handle such high-quality video, such as uncompressed HD and uncompressed 4K videos, which have rates of over 1 gigabit data per second. Therefore, we researched PC-cluster-based video stream server system to handle such a high-quality video streams. We have developed video server system with 24-Gbit/s maximum throughput by combining 16 PCs, 8 general storage systems and 20-Gbit/s InfiniBand inter-cluster network. To respond to demands for delivering video data streams to more video production sites, we propose a new communication method over an inter-cluster network that offers higher total throughput. We implemented the new communication method on a PC-cluster-based server system prototype and evaluated system performance. By combining 24 PCs, 12 storages and one InfiniBand switch, we realize 54-Gbit/s throughput video server system. In this paper, we describe the proposed communication method, hardware and software implementation method on PC cluster, as well as evaluation results.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2426","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2413","bibliographicIssueDates":{"bibliographicIssueDate":"2013-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"54"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
