Furukawa Electric Co., Ltd. announced on January 15, 2021 that it has developed SDN (Software Defined Networking) technology that creates a virtual network using software for EPON devices currently used for optical fiber access lines such as Internet communications.The capacity of optical fiber access lines is increasing toward the society of Society 5.0, and this technology uses the line status as the service usage in the optical line terminal OLT (Optical Line Terminal) on the telecommunications company side. It is said that it will be an important factor for future network operation and sophistication of optical access infrastructure, such as automatic control according to the situation and dynamic control to the optimum setting according to the communication demand.The technology developed this time is a technology for realizing virtualization in EPON standardized by the IEEE (Institute of Electrical and Electronics Engineers), and is an open source called "VOLTHA" promoted by ONF (Open Network Foundation). It is the base.The development results of this technology are published worldwide on ONF.Local 5G security with Trend Micro Mobile Network Security ™
