The 2013 Software-Defined Network Summit (SDN) was held in Hsinchu, Taiwan on October 9th, 2013. This year, the 2013 SDN Summit was co-organized by the National Center for High-performance Computing (NCHC), the Computer Society of the Republic of China (CSROC), the Alliance of Cloud Computing Technologies and Applications (ACCTA), and the Industrial Technology Research Institute (ITRI). As part of the conference, the NCHC invited scholars to share their latest R&D in SDN and to present their SDN research results. Both developed and ongoing SDN-related issues were featured at the 2013 SDN Summit.

SDN is an emerging network architecture that provides an opportunity for enterprises and users to simplify network management as well as to reduce the costs associated with networking equipment. Many large enterprises such as Google, Facebook, Yahoo, and Microsoft have invested in the SDN architecture in recent years, and as a result, are driving this trend in networking reform. In order to face the challenges that SDN presents, the NCHC has developed a transnational SDN testing platform. The NCHC also collaborates with domestic academic research institutes to share SDN resources via the Taiwan Advanced Research and Education Network (TWAREN) over which the SDN architecture and OpenFlow technologies are jointly researched. Via these efforts, the NCHC hopes to drive domestic technological development and achieve international SND standards.

During the conference, the NCHC’s Director Ce-Kuen Shieh explained how SDN separates the control and data transfer functions of the networking equipment so that the networking devices, once considered nothing more than a "black box" to people, can now be creatively utilized by anyone and everyone. The International Data Corporation (IDC) puts the output value of SDN at an estimated US $360 million this year alone. At the same time, it estimates that that figure will grow tenfold in the next three years. This serves to illustrate the high expectations of all SDN-related sectors.

The NCHC began developing SDN technologies in 2010. It built Taiwan’s first SDN testbed which linked to the USA's International Global Environment for Network Innovations (iGENI) and the Research Infrastructure for large-Scale network Experiments (RISE) testbed on Japan's Gigabit Network (JGN-X). The NCHC also developed numerous SDN-based networking technologies in collaboration with National Cheng Kung University (NCKU), National Central University (NCU), National Kaohsiung University of Applied Sciences (NKU), National Taiwan University of Science and Technology (NTUST), National Chiao Tung University (NCTU), and Chunghwa Telecom Laboratories. Utilizing this collaborative foundation, the NCHC hopes to jointly create a vision for SDN together with academia.

During the conference, Professor Han-Chieh Chao, President of National Ilan University and the Chairman of the CSROC, spoke on the opportunities and challenges that SDN offers. He explained that while technology changes rapidly, "pure" hardware cannot be adjusted, therefore, virtualization technologies can be useful tools in overcoming this bottleneck. The core value of SDN is to optimize network bandwidth via virtualization and utilize network bandwidth to its fullest extent, however, there remain numerous challenges in the development of SDN architecture such as the compatibility between individual products, the integration of SDN in different units, the profit distribution among telecommunication operators after commercialization, and security and privacy issues derived from the control of packages. It is undeniable that SDN is the wave of the future and that it will drive explosive progress in the field of networking. It is hoped that all sectors will accept this great challenge!

Dr. Te-Lung Liu of the NCHC also shared his experience on the establishment and management of a large SDN testing environment. The NCHC proposed a solution for large multi-domain management on its SDN testbed and presented it at both the GENI Engineering Conference (GEC) and the Supercomputing Conferences in 2011 and 2012 (i.e. SC11 and SC12). It illustrated the cross-unit, cross-nation, and cross-ocean operation possibilities of SDN. Dr. Te-Lung Liu also shared his opinion on the future trends of SDN which include interface standardization and innovative applications and services.

Next, Dr. Yu-Huang Chu of Chunghwa Telecom Laboratories, Professor Jiann-Liang Chen of NTUST’s Science and Technology Department of Electrical Engineering, Professor Chu-Sing Yang of NCKU's Department of Electrical Engineering, Deputy Director Li-Der Chou of the NCHC, Deputy Chief Hung-Chi Hsu of the ITRI Information and Communications Research Laboratories Broadband Network and System Integration Technology Section, and Director Shieh-Yuan Wang of NCTU's Institute of Computer Science and Engineering shared their latest developments in cloud-based SDN applications, SDN services, and SDN key control technologies. These talks spurred many in-depth discussions on the core aspects of R&D in SDN.

Finally, representatives of Accton Technology, Brocade, Cisco Systems Taiwan, EstiNet Technologies, and Xinguard, as well as the Industrial Economics and Knowledge Research Center (IEK) of ITRI, discussed the current status of SDN in industry. They unanimously agreed that SDN was no longer limited to research within laboratories and that it will become a star within the industrial sector as well. In the very near future, it is expected that domestic academia and industry will join in the continued development of SDN.

The NCHC possesses strong technological capabilities and a wealth of experience. In addition to assisting with the domestic establishment of an SDN environment, the NCHC will jointly expand platform functions in response to different demands, so as to drive research in domestic academia and development and testing in the industrial sector. The NCHC hopes that this will inspire academia and the industrial sector to become more creative and develop more applications that will benefit the general public.
