Launch of IOWN Network Solution for 400Gbps High-Speed Inter-Data Center Connections that Reduces Construction and Operation Costs by 50% and Power Consumption by 40%

Integration of technology of NTT’s IOWN and IP Infusion, a leading US software company

SANTA CLARA, Calif.--(BUSINESS WIRE)--The IOWN Network Solution (400G) (hereinafter, The Solution) combines the IOWN-related technologies of NTT Corporation (NTT) and those of IP Infusion Inc. (IP Infusion) (*1), a leading software company in the United States, to realize high-speed, high-capacity, and low-power consumption communication.

NTT and ACCESS Co., Ltd. (ACCESS) (*2) have been strengthening the collaboration of the R&D and productization of network OS as well as sales and support in the global market through a capital and business alliance (*3) to develop the IOWN.

Today, nine companies, NTT, NTT Advanced Technology Corporation (NTT-AT), ACCESS, IP Infusion, Broadcom Inc. (Broadcom), Edgecore Networks Corporation (Edgecore), UfiSpace Co., Ltd. (UfiSpace), Fujitsu Optical Components Ltd. (FOC), and NEC Corporation (NEC), announced that they are ready to provide the solution to realize 400Gbps high-speed data center connectivity by their close collaboration, with their technologies and products. This solution will be sold by NTT-AT and IP Infusion.

This solution allows customers such as data center operators and telecommunication carriers to construct simple and lower-cost inter-data center networks based on 400G ZR/ZR+ for high-speed and long-distance transmission. This will contribute to a 50% reduction in the construction and operation costs of the network equipment (*4), a 40% reduction in power consumption (*4), and rack space.

1. Background

The rapid increase in power consumption has become a social issue as the data amount in data centers increases due to the development and spread of the usage of generative AI and machine learning. As the data amount is expected to increase further, there are growing expectations for low-cost construction of high-speed connections between data centers to distribute expanding data calculation processing and low-power consumption.

In constructing high-speed data center connections, software-hardware integrated network devices with a limited number of optical transceiver options are usually used in the current network, which poses a problem in terms of investment efficiency. In response, there is a need to improve investment efficiency through software and hardware disaggregation and the flexible selection of optical transceivers.

2. IOWN Network Solution (400G) Overview

This solution provides a switch/router capable of long-distance transmission at 400Gbps. Its software and hardware are disaggregated, consisting of a network OS (software), white box switches/routers (hardware), and a 400G ZR/ZR+ optical transceiver (optical transceiver). Depending on needs, customers can combine optical transceivers that comply with the open standard and are fully validated.

Features of IOWN Network Solution (400G)

1. FOC and NEC optical transceivers are equipped with NTT Innovative Devices Corporation's Photonics-Electronics Convergence devices that achieve low-power and stable transmission performance and comply with the open standard specifications.
2. A switch/router is realized by combining Network OS and white box switch/router, and customers can select the appropriate combination from the multiple white box switches/routers and optical transceivers to meet their needs. (Fig. 2)
3. Combining the transponder functions in switches/routers reduces procurement and maintenance costs, power consumption, rack space usage, and construction lead time (Fig. 3).
4. Network OS combines NTT and ACCESS/IP Infusion technologies to provide a rich set of functions that contribute to advanced maintenance and operation quality improvement of customer networks.

3. Solution Providing Formation

This solution includes components with one-stop and total support, from construction to 24/7 maintenance and operation (refer to Figure 4).

5. Future Developments

NTT, NTT-AT, ACCESS, IP Infusion, Broadcom, Edgecore, UfiSpace, FOC, and NEC will keep collaborating with their technologies and products to meet the needs for high-speed and large-capacity connections between data centers, high-speed and large-capacity back-end networks in data centers, and reduction of power consumption.

In addition, we will meet the needs for the advancement of data center-related networks, such as the realization of high-capacity, low-delay, and low-power communication between data centers and various sites by connecting to IOWN APN.
