By managing the delay,bandwidth, and packet loss parameters, it allows us to allocate our available resourcesbetween applications in a reasonable way. In today's life, it is general that manyapplications run at the same time. As a critical type of resource, bandwidth would beshared without principle which leads to interference. Therefore, “important”applications cannot get enough bandwidth to transmit data. To solve these problems,the end-to-end bandwidth resource allocation scheme is proposed to support Quality ofService (QoS) for various types of traffic based on the user QoS demand.The main goal of this system is to provide high QoS performance for highpriority flows. In order to meet this goal, this system considers the flow priority and thedynamic characteristics of the network. In addition, feasible paths are calculated for allthe traffic flows that can satisfy the user bandwidth demands. In order to mitigate theflow performance degradation and congestion, the controller checks the linkbandwidths by reserving the required bandwidths for incoming flows. If the linkbandwidth is smaller than the predefined threshold value, the link is defined as thebottleneck link and reroute the highest priority flow from the bottleneck link to analternative link that has enough bandwidth for the rerouting flow. Furthermore, toimprove the performance and to ensure the QoS of the high priority flows, a queuemechanism is used which is provided by the OpenFlow at the data link level. Thisresearch will try to accommodate as much traffic as possible, and study the effect ofrouting on a rather general mix of QoS traffic types.The effectiveness of the proposed scheme is described on the emulated SDNnetwork. The proposed scheme is compared with the conventional shortest pathscheme, multipath routing scheme in the various network topology. Furthermore, theperformance of the proposed scheme is compared with the popular flow schedulingscheme Hedera in the data center network topology. The improvement of QoS traffictype is quantified in terms of throughput, delay, jitter and packet loss rate, respectively.Based on the experiments, the researcher observed that the proposed method(QoS_based Traffic Engineering Approach) QT offers a significant improvementcompared to a static, traditional IP network and the multipath network environment byivproviding better performance in terms of packet loss rate for the QoS traffics and greatimprovement in link utilization."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value":[]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-01-22"}],"displaytype":"preview","filename":"QoS-Based Traffic Engineering in Software Defined Networking.pdf","filesize":[{"value":"3601 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/4555/files/QoS-Based Traffic Engineering in Software Defined Networking.pdf"},"version_id":"ec3d8f85-60e3-4a8b-aad2-269f18025e98"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"","subitem_journal_title":"","subitem_pages":"","subitem_volume":""}]},"item_1583103147082":{"attribute_name":"Conference papers","attribute_value_mlt":[{"subitem_acronym":"","subitem_c_date":"","subitem_conference_title":"","subitem_part":"","subitem_place":"","subitem_session":"","subitem_website":""}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{"subitem_book_title":"","subitem_isbn":"","subitem_pages":"","subitem_place":"","subitem_publisher":""}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_awarding_university":"Unversity of Computer Studies, Yangon","subitem_supervisor(s)":[{"subitem_supervisor":""}]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Thazin, Nwe"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Thesis"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2019-11"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"http://onlineresource.ucsy.edu.mm/handle/123456789/2477"},"item_title":"QoS-based Traffic Engineering in Software Defined Networking","item_type_id":"21","owner":"1","path":["1597824322519"],"publish_date":"2020-01-22","publish_status":"0","recid":"4555","relation_version_is_last":true,"title":["QoS-based Traffic Engineering in Software Defined Networking"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-03-24T23:12:37.132423+00:00"}
