The pseudo full-map directory scheme is one of the schemes which reduce the size of the directories. In this scheme, a hierarchical multicast scheme is used combined with other schemes such as multicast to neighbors and 1-to-1 communications. In this report, we examine some hierarchical multicast schemes for the pseudo full-map directory scheme.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"216","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"209","bibliographicIssueDates":{"bibliographicIssueDate":"1994-07-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"66(1994-ARC-107)","bibliographicVolumeNumber":"1994"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
