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 2020  Graduate Technical English  Spring semester  Graduate, IE  Master's program  2020  回路シミュレーション  Spring semester  Undergraduate, daytime  2020  コンピュータネットワーク  Spring semester  Undergraduate, daytime  2020  通信・ネットワーク  Spring semester  Undergraduate, mainly nighttime  View details...   ■ Education and research activities in foreign countries Lecture on the topic of "Case studies in Internet of Things with Artificial Intelligence"  2021/09-Present  Thailand  Dissertation committee member for PhD thesis  2020/12-Present  USA  A Member of the Board of Examiners of PhD thesis  2020/12-Present  India  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  Performance of Elastic Optical Network with Limited Slicers  Nattapong Kitsuwan and Kaito Akaki  ICE Express  -  2022  Paper  Yes  Resolving Load Imbalance State for SDN by Minimizing Maximum Load of Controllers  Ukrist Srisamarn, Lapas Pradittasanee, Nattapong Kitsuwan  Journal of Network and Systems Management  -  2021  Paper  Yes  Spectrum Allocation Scheme Considering Spectrum Slicing in Elastic Optical Networks  Nattapong Kitsuwan, Kaito Akaki, Praphan Pavarangkoon, Avishek Nag  JOURNAL OF OPTICAL COMMUNICATIONS AND NETWORKING  13/ 7, 169-181  2021/07  10.1364/JOCN.422915  Paper  Yes  Elastic Optical Network with Spectrum Slicing for Fragmented Bandwidth Allocation  Nattapong Kitsuwan, Praphan Pavarangkoon, Avishek Nag  Optical Switching and Networking  38  2020  Paper  Yes  Single Tag Scheme for Segment Routing in Software-Defined Network  Nattapong Kitsuwan, Eiji Oki, Takashi Kurimoto, and Shigeo Urushidani  Springer Telecommunication Systems  74/ -, 173-184  2020  View details...   ■ Research presentations Oral presentation for an academic conference  Caching Scheme Considering Location of Servers in Content Centric Network  IEICE ソサイエタィ大会  1-4  No  K.
