However, the existing peer to peer streaming system has problems which cannot switch stream contents smoothly because a peer finds the parent peer which can send new stream contents only after decision of switching. In this paper, We present the design, implementation, and evaluations of a peer to peer media streaming system with smooth switching. In this system, peers construct backup routes beforehand and use one in case of switching stream channels. Each peer which has similar contents forms a group and constructs the backup routes on the other.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"66","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"61","bibliographicIssueDates":{"bibliographicIssueDate":"2009-02-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"21(2009-IOT-4)","bibliographicVolumeNumber":"2009"}]},"relation_version_is_last":true,"weko_creator_id":"10"}}
