This is being led by the SEBA project of the Open Network Foundation (ONF), an organization that promotes the spread of SDN.The purpose is to virtualize optical access technologies such as PON (Passive Optical Network) and G.fast, and in addition to FTTH, mobile backhaul and fronthaul (connection part between master station and slave station of mobile phone base station) Is also envisioned.In this SEBA activity, the open source project "VOLTHA (Virtual OLT Hardware Abstraction)" is promoting the virtualization of PON.Major carriers such as AT & T in the US, Deutsche Telekom, and NTT are participating.The purpose is to execute the functions of optical access equipment such as optical network units (OLT / ONU) on general-purpose servers / devices or in the cloud so that they can be controlled from the SDN controller.The aim is to automate PON control Optical access is used for Internet connections, IP phones, IPTV / video distribution, etc., but its applications will diversify with the spread of IoT / AI services.Mr. Takuzo Matsumoto of Furukawa Electric says that virtualization of PON is indispensable in such a world.Based on VOLTHA, Furukawa Denko has developed SDN technology that virtualizes OLT / ONU used for EPON (Ethernet PON), which is the mainstream in Japan, and builds a virtual network by software.This makes it possible to automatically control the line status according to how the service is used, and to dynamically change and optimize the settings according to demand.In the existing system, different OLT / ONU devices are used for each service, and specialized engineers perform the setting work on site.Hardware is standardized by virtualizing this.According to Mr. Kenichi Goto of Furukawa Electric, "OLT / ONU is becoming a white box as well as data center switches," and the virtualized EPON that runs on such general-purpose hardware can be centrally integrated from the SDN controller. Allow control.The ultimate goal is to realize dynamic control by linking higher-level applications, operating systems, AI and SDN controllers.Local 5G security with Trend Micro Mobile Network Security ™
