NoLimit releases Architecture 1.0, transforming Ethernet for AI and HPC at scale
Architecture 1.0 opens a new era of interoperable, high-performance Ethernet innovation.
San Francisco. The NoLimit Foundation today announced the release of Architecture 1.0, a comprehensive Ethernet-based communication stack engineered for the demands of modern AI and HPC workloads. The release marks a critical step in redefining Ethernet for next-generation, data-intensive infrastructure.
Architecture 1.0 delivers a high-performance, scalable, interoperable solution across every layer of the stack, including NICs, switches, optics, and cables, enabling seamless multivendor integration and accelerating innovation throughout the ecosystem.
By promoting open, interoperable standards that prevent vendor lock-in, the architecture is driving industry-wide adoption. With implementations and compliance programs already in progress, the foundation is paving the way for a unified, accessible ecosystem across the sector.
The release is the result of an outstanding collaboration among AI, HPC, and networking experts, system and silicon vendors, and network operators. It incorporates a wealth of knowledge and ideas about applications, transport protocols, congestion control, direct memory access, Ethernet link and PHY technologies, and network security. It is a landmark for the industry and a substantial boost to Ethernet's role in AI and HPC.
Addressing critical infrastructure needs
- Modern RDMA for Ethernet and IP. Intelligent, low-latency transport for high-throughput environments.
- Open standards and interoperability. No vendor lock-in, and faster innovation across the ecosystem.
- End-to-end scalability. From routing and provisioning to operations and testing, the architecture scales to millions of endpoints.
Designed for real-world integration
Built on the globally adopted Ethernet standard, Architecture 1.0 simplifies deployment across the full technology stack, from hardware to applications. Its familiarity, combined with robust tooling, makes it especially valuable to cloud infrastructure operators, hyperscalers, DevOps teams, and AI engineering leads looking for a low-friction adoption path.
This release is a major milestone in the foundation's mission to redefine Ethernet for the age of AI and high-performance computing. It is the product of unprecedented collaboration across the industry, and it delivers the low-latency, high-bandwidth, intelligent transport that the most demanding workloads of today and tomorrow require. The 1.0 release is a beginning, not an end.
