ac米兰中国官网 Co., Ltd. (Head office: 2-3, Marunouchi 2-chome, Chiyoda-ku; President: Keiichi Kobayashi) is pleased to announce that it has developed SDN (Software Defined Networking) technology that can use software to create a virtual network in EPON^{(note 1)}devices, which are used in fiber access lines for the Internet and other communications. The company is promoting higher-capacity ac米兰中国官网 lines toward Society 5.0. By automatically controlling the line status according to how the service is used and dynamically controlling the optimal settings according to communications demand in the OLTs (Optical Line Terminals) on the telecommunications company side, this technology will serve as an important element in the sophistication of future network operation and optical access infrastructure.

In the past, optical fiber access lines were mainly used for high-speed internet connection, telephone, and video distribution purposes. In recent years, however, expectations and demand for optical fiber access lines have grown, and they have come to be used in the fronthaul part of mobile and wireless communications, and are expected to be used in IoT infrastructures, mobility infrastructures, and more. With the establishment of the “ac米兰中国官网, Vision 2030,” the Group is promoting R&D in the fusion domains of information and mobility as well as development to increase added value in optical fiber access lines.

The relevant technology aims to achieve virtualization in EPON, which is standardized by the American IEEE (Institute of Electrical and Electronics Engineers). It will serve as the base for the open-source software project VOLTHA,^{(note 2)}
which is promoted by the ONF (Open Network Foundation).^{(note 3)}The development results of this technology have been made available worldwide by the ONF.^{(note 4)}
There are two types of global access networks using ac米兰中国官网s: GPON^{(note 5)}and EPON, which are promoted and formulated by, respectively, the ITU-T (International Telecommunication Union Telecommunication Standardization Sector) and the IEEE. In Japan, the IEEE type is used by communications and cable TV operators. The relevant technology is an ac米兰中国官网 line technology that supports IEEE’s EPON.

Japan and other countries are facing the social issue of a reduced labor force due to an aging population, and this issue is now becoming apparent even in the operation of information and communications networks. It is said that with the current technology and methods, it will be difficult to achieve operation that satisfies the needs of a diverse market. Thanks to this technology, in the future, it will be possible to automate the operation of the optical line terminals of ac米兰中国官网 lines, so the personnel involved in such operation can be placed in sectors with higher added value, which could further boost economic productivity.
