Figure 1: Scope of Arrcus Network OS Software

As AI continues to be deployed throughout society and the services available become more sophisticated, AI-related data traffic is increasing exponentially. This trend is driving a growing need for network infrastructure that can seamlessly connect data centers, cloud platforms, 5G/6G networks, and edge environments.

Arrcus develops advanced routing and switching platforms based on Ethernet networking technology and provides industry-leading networking software that meets the diverse needs of network operators and enterprise customers.

The Network Operating System (OS) software developed by Arrcus can operate in a unified manner across data center clusters, from the edge to multi-cloud environments, enabling faster deployment and centralized management. It does not require dedicated hardware and can run on generic “white box” components, allowing for the placement of white box hardware equipped with the optimal silicon components. Customers that have implemented this software have achieved over 40% reduction in total cost of ownership (TCO) across multiple use cases.

Under this partnership agreement, 1Finity will offer the complete range of Arrcus solutions as its business partner, and will jointly develop go-to-market plans to expand its business globally with a primary focus on Japan, targeting network operators, enterprise customers and data center operators. In addition, the collaboration will extend to business partners on a global scale, not limited to the Fujitsu Group, and build comprehensive total solutions covering network design to maintenance and operation by managed service collaboration to provide optimal value to customers.

Fujitsu will leverage its global customer base to provide flexible and scalable solutions that can adapt to rapidly changing market needs, while combining the Arrcus business model with Fujitsu's strengths in AI services and computing technologies to become a next-generation infrastructure service provider for the global market.

Shekar Ayyar, Chairman & CEO, Arrcus Inc. comments:

“Flexible networks that combine innovation in software, silicon, and optics are of critical importance for AI data centers and 5G/6G connected inference edges. We are super excited to announce our strategic partnership with Fujitsu and 1Finity to bring our combined strengths for Fujitsu internal use as well as for enterprises, service providers, and cloud/neo-cloud operators worldwide.”

Masaaki Moribayashi, Corporate Executive Officer, Fujitsu Limited, Representative Director, CEO, 1Finity Inc. comments:

“As the amount of AI-related data transfer increases in both volume and complexity, the role of networks has become more important than ever before. Arrcus's products, including its Network OS Software, are innovative and offer exceptional performance which will help us to provide optimal network solutions and meet our customers' needs. We look forward to achieving breakthroughs in networking through this partnership.”
