NTT commences sales of the network OS Beluganos
Provision of a white-box compatible network OS that achieves a 20% reduction
in TCO１compared to dedicated devices
Tokyo – March 28, 2023 – NTT Corporation (NTT) has developed a network OS compatible withwhite-box devices2, and NTT Advanced Technology Corporation (NTT-AT) will commercialize itthrough the release of their software Beluganos3, an in-house produced network OS for carriers on
March 31. In addition to improving performance, NTT and NTT-AT will boost flexibility and economic
efficiency through their product construction.
1．BackgroundIn recent years, due to the proliferation of IoT (Internet of Things) and faster networks such as 5G,
societies are rapidly transforming to be data-driven, meaning that data determines analysis andactions. The NTT Group is responding to these social trends by utilizing innovative technologies
centered on optics to address the expected increase in data volume and future power consumption.
As a high-speed network and information processing infrastructure enabling large-capacity
communication and ultra-low power consumption, the IOWN concept4 proposed by the NTT Group isfundamental to these endeavors. On March 16, 2023, NTT Group companies launched the first IOWN
service, the All-Photonics Network (APN) IOWN1.05 service. By continuing to develop the IOWN
services, NTT Group companies, including NTT-AT, plan to provide low-power consumption servers
utilizing their newly developed photonic-electronic convergence devices. From the launch of IOWN
2.0 onwards, NTT will apply these photonic-electronic devices not only to networks but to the entire
world of computing. Recently, they have begun releasing IOWN services and products at an earlystage to create new value with partners, with the commercial provision of Beluganos marking thefollowing initiative.
Today's networks often rely on network equipment that integrates hardware and software. This setup
reduces investment efficiency, as customers can only select from a limited product lineup provided
by vendors. NTT’s innovative solutions make these restrictions a thing of the past.
2．Outline of the initiative
Beluganos is a network OS compatible with white-box equipment and based on the technology that
NTT has researched and developed so far in collaboration with IP Infusion, a global partner that also
participates in the IOWN Global Forum6.
Following verification of the network’s high reliability, NTT Communications decided to introduce
Beluganos into their commercial network infrastructure in combination with white box equipment tosupport their network services. Operation of the service will commence on March 31, 2023. From thenon, NTT-AT will provide sales and support for the Beluganos service.
Beluganos utilizes a white-box device to separate hardware and software, making it possible to selectany hardware flexibly, improving investment efficiency compared to conventional network equipmentthat integrates hardware and software, and achieving a 20% reduction in TCO compared to dedicateddevices. In addition, Beluganos features enhanced maintenance, operation, and monitoring functions
necessary for quick response to network failures, resulting in improved operational quality forcustomers of telecommunications carriers and data center operators.

4．Future plans
Through the use of white-box equipment and co-creation with partners, the NTT Group promotes
open innovation and works to transform its own networks and upgrade the networks of its customers.

By strengthening the DevOps system through development, in-house operation, and sales andsupport, NTT will undertake continuous development and continuously upgrade Beluganos.
Furthermore, they will continue to work with global partners to develop and socially implement IOWN
services and products in order to provide low power consumption servers equipped with future
photonic-electronic convergence devices.

Notes
120% reduction in TCO: Total Cost of Ownership. Using white-box equipment and Beluganos instead of conventional
hardware/software-integrated dedicated devices will reduce the total cost of goods and services, including maintenance,by 20%.

4The IOWN Concept: IOWN(Innovative Optical and Wireless Network) is a network and information processing platformthat includes terminals and provides high-speed, large-capacity communication and enormous computational resources
using innovative technologies centered onoptics. Through IOWN, we will contribute to the realization of a prosperous
society by creating various services and new value in a wide range of fields.
5 APN IOWN1.0: the first commercial service implementing the IOWN concept in the All-Photonics Network, which

introduces optics exclusively in all sections of the communication networkhttps://www.ntt-east.co.jp/release/detail/20230302_01.html (in Japanese)

6 IOWN Global Forum: a new forum that brings together people in different industries to promote the development of a

new communication platform that can meet the future demands of data and information processing. This includes thedevelopment of new technologies, frameworks, technical specifications, and reference designs, and particularly of the AllPhotonics Network, which encompasses silicon photonics, edge computing, and wireless distributed computing.
