The main objectives of the dissertation\u003cbr /\u003ewas to provide fairness from various aspects, including rate and distance fairness, to\u003cbr /\u003eOBS networks without degrading the loss probability or throughput.\u003cbr /\u003e　　This dissertation proposes a rate fairness preemption (RFP) scheme to achieve\u003cbr /\u003emax-min fair bandwidth allocation (FBA) or rate fairness in OBS networks. Core\u003cbr /\u003eswitches in RFP do not need to have a function for monitoring both the arrival and\u003cbr /\u003eloss rates of flows. Methods of adaptive and fixed max-min rate allocation are\u003cbr /\u003eintroduced. RFP based on fixed max-min rate allocation is the simplest way of\u003cbr /\u003eachieving max-min FBA in OBS networks because it does not require any additional\u003cbr /\u003econtrol message to update the arrival or fairly allocated rates as required by existing\u003cbr /\u003eFBA schemes. A discrete-time Markov chain-based model for analysis of the burst\u003cbr /\u003eloss probability for flows in RFP-based OBS networks is proposed. The performance\u003cbr /\u003eof RFP was demonstrated through both analyses and simulations.\u003cbr /\u003e　　In addition, this dissertation proposes a technique of deflection routing (DR),\u003cbr /\u003ecalled max-min DR (MMDR), to reduce losses when max-min FBA is achieved in\u003cbr /\u003eOBS networks. The proposed DR strategy can be adapted to preemption-based and\u003cbr /\u003erate-control-based FBA schemes. In this research, we integrated MMDR with RFP\u003cbr /\u003eand derived a new scheme called rate fairness preemption with deflection routing\u003cbr /\u003e(RFP-DR). The simulation results indicate that RFP-DR can isolate and protect\u003cbr /\u003eservices as RFP does, but RFP-DR yields the lower total burst loss probability.\u003cbr /\u003e　　Although FBA can be achieved in OBS networks, the actual transmission rate of\u003cbr /\u003eflows not only depends on the fairly allocated rate but also its burst loss probability\u003cbr /\u003edue to the high-loss characteristic of OBS. The burst loss probability of flows in OBS\u003cbr /\u003enetworks tends to increase with larger hop counts. Therefore, rate fairness or FBA\u003cbr /\u003eshould be provided with distance fairness (fairness among flows with different hop\u003cbr /\u003ecounts) so that we can achieve real fairness in the sense of fair transmission rates.\u003cbr /\u003eConsequently, this dissertation introduces a rate and distance fairness preemption\u003cbr /\u003e(RDFP) scheme to achieve max-min FBA while ensuring distance fairness for traffic\u003cbr /\u003etransmitted under the max-min rate.\u003cbr /\u003e　　The analytical and simulation results indicate that the proposed schemes\u003cbr /\u003eeffectively solve fairness problems in OBS networks without degrading the total\u003cbr /\u003eburst loss probability. In addition, the proposed schemes are simple enough to\u003cbr /\u003eimplement in practical networks because of their low computational complexity.", "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1289号", "subitem_description_type": "Other"}]}, "item_1_select_14": {"attribute_name": "所蔵", "attribute_value_mlt": [{"subitem_select_item": "有"}]}, "item_1_select_16": {"attribute_name": "複写", "attribute_value_mlt": [{"subitem_select_item": "印刷物から複写可"}]}, "item_1_select_17": {"attribute_name": "公開状況", "attribute_value_mlt": [{"subitem_select_item": "要旨のみ公開"}]}, "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": "2009"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "ORAWIWATTANAKUL, Tananun", "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1289_要旨.pdf", "filesize": [{"value": "244.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 244400.0, "url": {"label": "要旨・審査要旨", "url": "https://ir.soken.ac.jp/record/1504/files/甲1289_要旨.pdf"}, "version_id": "32ff31e4-04fc-4505-9af5-5dc2d7f29de0"}]}, "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": "Fairness Provisioning in Optical Burst Switching Networks", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Fairness Provisioning in Optical Burst Switching Networks"}, {"subitem_title": "Fairness Provisioning in Optical Burst Switching Networks", "subitem_title_language": "en"}]}, "item_type_id": "1", "owner": "21", "path": ["19"], "permalink_uri": "https://ir.soken.ac.jp/records/1504", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-06-09"}, "publish_date": "2010-06-09", "publish_status": "0", "recid": "1504", "relation": {}, "relation_version_is_last": true, "title": ["Fairness Provisioning in Optical Burst Switching Networks"], "weko_shared_id": -1}
