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.”

CAPE CANAVERAL, Fla. (AP) — An ailing astronaut returned to Earth with three others on Thursday, ending their space station mission more than a month early in NASA’s first medical evacuation.

SpaceX guided the capsule to a middle-of-the-night splashdown in the Pacific near San Diego, less than 11 hours after the astronauts exited the International Space Station.

“It’s so good to be home,” said NASA astronaut Zena Cardman, the capsule commander.

It was an unexpected finish to a mission that began in August and left the orbiting lab with only one American and two Russians on board. NASA and SpaceX said they would try to move up the launch of a fresh crew of four; liftoff is currently targeted for mid-February.

Cardman and NASA’s Mike Fincke were joined on the return by Japan’s Kimiya Yui and Russia’s Oleg Platonov. Officials have refused to identify the astronaut who had the health problem or explain what happened, citing medical privacy.

While the astronaut was stable in orbit, NASA wanted them back on Earth as soon as possible to receive proper care and diagnostic testing. The entry and splashdown required no special changes or accommodations, officials said, and the recovery ship had its usual allotment of medical experts on board. It was not immediately known when the astronauts would fly from California to their home base in Houston. Platonov’s return to Moscow was also unclear.

NASA stressed repeatedly over the past week that this was not an emergency. The astronaut fell sick or was injured on Jan. 7, prompting NASA to call off the next day’s spacewalk by Cardman and Fincke, and ultimately resulting in the early return. It was the first time NASA cut short a spaceflight for medical reasons. The Russians had done so decades ago.

The space station has gotten by with three astronauts before, sometimes even with just two. NASA said it will be unable to perform a spacewalk, even for an emergency, until the arrival of the next crew, which has two Americans, one French and one Russian astronaut.
