In this dissertation, \u003cbr /\u003ewe address the issue how to provide QoS control and improve performance in OBS \u003cbr /\u003enetworks . \u003cbr /\u003e   In order to provide proportional differentiated services without or with absolute \u003cbr /\u003econstraints in bufferless OBS networks, a Dynamic Wavelength Selection (DWS) \u003cbr /\u003escheme is introduced to assign more and longer periods of wavelengths to higher \u003cbr /\u003epriority classes dynamically and efficiently due to wavelength-sharing. The inte- \u003cbr /\u003egration of DWS scheme and another proposed Delayed Burst Assignment (DBA) \u003cbr /\u003escheme improves the burst loss performance by giving the burst head packet (BHP) \u003cbr /\u003etwo opportunities of scheduling its data burst (DB). \u003cbr /\u003e   Furthermore, we propose two novel burst assembly algorithms with traMc shap- \u003cbr /\u003eing functions to reduce the variance of assembled traffc and improve the burst \u003cbr /\u003eloss performance, which are named advanced timer-based and sliding window-based \u003cbr /\u003eassembly algorithms. \u003cbr /\u003e   Finally, an edge buffering based OBS layer fast error recovery scheme is pro-- \u003cbr /\u003eposed to improve the TCP performance over OBS networks, in which lost bursts are \u003cbr /\u003eretransmitted at edge nodes without being reassembled. \u003cbr /\u003e   In general, all the proposed schemes solve many of the fundamental issues faced \u003cbr /\u003eby optical burst switching networks, thereby making OBS more practical and efii- \u003cbr /\u003ecient in the near future.\u003cbr /\u003e", "subitem_description_type": "Other"}]}, "item_1_description_18": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_1_description_7": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "総研大甲第1049号", "subitem_description_type": "Other"}]}, "item_1_select_14": {"attribute_name": "所蔵", "attribute_value_mlt": [{"subitem_select_item": "有"}]}, "item_1_select_8": {"attribute_name": "研究科", "attribute_value_mlt": [{"subitem_select_item": "複合科学研究科"}]}, "item_1_select_9": {"attribute_name": "専攻", "attribute_value_mlt": [{"subitem_select_item": "17 情報学専攻"}]}, "item_1_text_10": {"attribute_name": "学位授与年度", "attribute_value_mlt": [{"subitem_text_value": "2006"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "DU, Ping", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "0", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-02-17"}], "displaytype": "simple", "download_preview_message": "", "file_order": 0, "filename": "甲1049_要旨.pdf", "filesize": [{"value": "269.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 269500.0, "url": {"label": "要旨・審査要旨", "url": "https://ir.soken.ac.jp/record/859/files/甲1049_要旨.pdf"}, "version_id": "467ecd43-923a-4851-90ba-e69ab035581e"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-02-17"}], "displaytype": "simple", "download_preview_message": "", "file_order": 1, "filename": "甲1049_本文.pdf", "filesize": [{"value": "31.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 31600000.0, "url": {"label": "本文", "url": "https://ir.soken.ac.jp/record/859/files/甲1049_本文.pdf"}, "version_id": "fa662610-11b1-4fe9-829a-05cbcd353a82"}]}, "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": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "QoS Control and Performance Improvement Methods for Optical Burst Switching Networks", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "QoS Control and Performance Improvement Methods for Optical Burst Switching Networks"}, {"subitem_title": "QoS Control and Performance Improvement Methods for Optical Burst Switching Networks", "subitem_title_language": "en"}]}, "item_type_id": "1", "owner": "1", "path": ["19"], "permalink_uri": "https://ir.soken.ac.jp/records/859", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-02-22"}, "publish_date": "2010-02-22", "publish_status": "0", "recid": "859", "relation": {}, "relation_version_is_last": true, "title": ["QoS Control and Performance Improvement Methods for Optical Burst Switching Networks"], "weko_shared_id": -1}
