Semi-flexible grid configuration and two cost metrics are introduced to establish a regularity in frequency assignment and minimize disturbance in the upgrade process; both reduce the fragmentation in frequency assignment and the number of fibers necessary. Various investigations of different configurations elucidate that the number of fibers necessary is reduced about 10-15% for any combination of upgrade scenario, channel frequency bandwidth, and topology adopted.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会","subitem_publisher_language":"ja"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1587/transcom.2021EBP3027","subitem_relation_type_select":"DOI"}}]},"item_9_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright(C)2021 IEICE","subitem_rights_language":"en"}]},"item_9_source_id_7":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"0916-8516","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"HASEGAWA, Hiroshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"YASUDA, Takuma","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"MORI, Yojiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"SATO, Ken-ichi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-05-20"}],"displaytype":"detail","filename":"e104-b_12_1514.pdf","filesize":[{"value":"5.6 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/2002843/files/e104-b_12_1514.pdf"},"version_id":"787324fa-13ff-43a9-9dc9-ace281f10ddc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"semi-flexible grid","subitem_subject_scheme":"Other"},{"subitem_subject":"periodic network upgrade","subitem_subject_scheme":"Other"},{"subitem_subject":"fragment mitigation","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Fragmentation-Minimized Periodic Network-Bandwidth Expansion Employing Aligned Channel Slot Allocation in Flexible Grid Optical Networks","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fragmentation-Minimized Periodic Network-Bandwidth Expansion Employing Aligned Channel Slot Allocation in Flexible Grid Optical Networks","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"17","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-05-20"},"publish_date":"2022-05-20","publish_status":"0","recid":"2002843","relation_version_is_last":true,"title":["Fragmentation-Minimized Periodic Network-Bandwidth Expansion Employing Aligned Channel Slot Allocation in Flexible Grid Optical Networks"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-01-16T04:39:24.128109+00:00"}
