Network administrators have to cope with a lot of difficulties to support the request. They have to learn configuration based on product's manual. Implementation of a new solution is difficult due to the limitation of product operating system. We study network technologies to make the network easier to be controlled, implement, and less complex. Software Defined Networking SDN separates the network control and data forwarding planes. This allows network engineers and administrators to respond quickly to changing requirements of the network from a centralized controller. The network administrator can avail of improved network programmability to flexibly control the physical switches from the controller, which runs all the intelligent control and management software, regardless of the vendor or the model of the switches used. OpenFlow is a widely known protocol for SDN networks that enables the controller to interact with the forwarding plane of the switches and thus make adjustments to the network. The hardware switches can also use OpenFlow messages to inform the controller when a packet arrives with no specified forwarding instructions. The forwarding instructions are based on a flow entry. The controller specifies the set of parameters and how packets that match the flow entry should be processed. Optical packet/burst switching Optical packet switched networks are emerging as a serious future candidate for the evolution of optical telecommunication networks to support high-throughput services such as voice over IP (VoIP) and high quality video streaming on demand. In an optical network with optical packet switches interconnected with optical fibers running wavelength division multiplexing (WDM), packets are transmitted from source to destination without any optical-electrical-optical (O/E/O) conversion. Buffering at intermediate nodes is eliminated. The use of optical buffering through fiber delay lines (FDLs) to delay a packet for a specified amount of time while waiting for a future transmission may not feasibly to provide a large delay time. Network control and management In an IP network, a packet travels from source to destination using a routing table to guide a route. The routing table is dynamically configured using a routing protocol based on traffic condition. Adopting a suitable routing scheme can gain higher network throughput.    ■ Classes responsible within the university 2017  回路シミュレーション  Spring semester  Undergraduate, daytime  2017  大学院技術英語  Spring semester  Graduate, IE  2017  コンピュータネットワーク  Fall semester  Undergraduate, daytime  View details...   ■ Current research areas Theory of informatics  Information network    ■ Research keywords Software-defined network  Optical communications  Network control  Communication protocols    ■ Published papers Paper  Yes  Designing a Hadoop System Based on Computational Resources and Network Delay for Wide Area Networks  Tomohiro Matsuno, Bijoy Chand Chatterjee, Nattapong Kitsuwan, Eiji Oki, Malathi Veeraraghavan, Satoru Okamoto, and Naoaki Yamanaka  Springer Telecommunication Systems  -/ -, ---  2018  Paper  Yes  Heuristic Approach to Determining Cache Node Locations in Content-Centric Networks  Nattapong Kitsuwan, Hiroki Tahara, and Eiji Oki  IEEE Access  6/ -, 1542-1549  2017  2169-3536  10.1109/ACCESS.2017.2779452  Paper  Yes  A Disjoint Path Selection Scheme to Minimize Required Spectrum Slots in Elastic Optical Networks  Yuto Kishi, Nattapong Kitsuwan, and Eiji Oki  IEICE Transactions on Communications  J100-B/ 7, 458-468  2017  Paper  Yes  Performance of Throughput-based Q-routing  Nattapong Kitsuwan, Takumi Neda, and Eiji Oki  IEICE Communications Express  6/ 3, 137-141  2017  Paper  Yes  Computation Method for Betweenness using Graph Compression  Kazuharu Aramaki, Nattapong Kitsuwan, and Eiji Oki  IEICE Letter  J100-B/ 11, 934-939  2017/11  View details...   ■ Research presentations Oral presentation for an academic conference  Disjoint path selection in elastic optical networks  IEICE Technical Report, Photonic Network  116/ 386  No  Yuto Kishi, Nattapong Kitsuwan, and Eiji Oki  2018/03  Oral presentation for an academic conference  Implementation Technique for Traffic Splitting in OpenFlow Networks  IEICE Technical Report, Network System  No  Kazuharu Aramaki, Nattapong Kitsuwan and Eiji Oki  2017/10  Oral presentation for an academic conference  Disjoint path selection scheme in elastic optical networks considering modulation techniques  IEICE Technical Report, Photonic Network  116/ 386  No  Yuto Kishi, Nattapong Kitsuwan, and Eiji Oki  2017/01/11  Oral presentation for an academic conference  A Task Allocation Scheme in Hadoop Clusters Considering Computational and Network Resources for Wide Area Networks  IEICE Technical Report, Photonic Network  116/ 307  No  T.
