Network software company Arrcus Networks made several important announcements at the Mobile World Congress 2025 (MWC25) show in Barcelona this week. We visited the company several times over the days we were at the show to learn as much as possible about the various announcements. The company announced partnerships with NVIDIA, Actapio, Broadcom, ufiSpace, Liberty Global, Fujitsu, EVIDEN, Philips, and Lanner, many of whom were present when Arrcus made these announcements public. To summarize the four significant announcements, Arrcus announced Telco-Grade AI Ethernet Switch based on NVIDIA Spectrum chips, it enabled Actapio with Next-Generation Networking Fabric to build out AI clusters for Large Language Models, it enabled Liberty Global’s AI-Powered Telco capabilities with advanced video services for public safety and industrial automation, and it collaborated with Lanner to deliver telco-edge networks for the AI and 5G era.
The MWC25 show was all about AI, and Arrcus did not disappoint in its participation because of its announcement that its software is now available on NVIDIA’s Spectrum Ethernet platform to make a telco-grade AI switch. The joint solution is intended to be installed at telco edge, core, data center and cloud locations and the point of making this announcement at MWC25, a telco-oriented show, is that the switch system can be used for networking services like security and DCI and can be adapted for use with AI Inference and then as the market develops, AI-RAN.
Arrcus also announced that it is jointly developing a high-performance, lossless network for GPU connectivity for Actapio, a subsidiary of LY Corporation, for LLM Training on NVIDIA GPUs. As a network software company, Arrcus’s software is operating with Broadcom Tomahawk 5 on hardware built by systems company UfiSpace to connect Actapio’s AI processing clusters. Features available with the combined solution include RoCEv2, PFC, ECN and Dynamic load balancing.
