A letter from the chair: looking ahead to the rest of 2026 and beyond

Hello NoLimit community,

A warm welcome to all our new members, and my thanks to everyone who has contributed to our growth. The mission has not changed: establish the best Ethernet-based high-performance network for AI and HPC workloads. Together we are making real strides toward that goal, and with the first quarter behind us it is a good moment to look back at how far we have come and forward to what is coming.

Looking back

The past six months have been a period of remarkable growth. We began with a foundational vision and ten companies. Today the foundation counts more than 100 members representing a broad cross-section of the technology industry. That expansion is a testament to how important the mission is to the people wrestling with AI and HPC networking every day.

We made significant progress across the physical, link, transport, and software layers: new congestion management schemes, built-in security, and optimized packet delivery, all critical to the most intensive workloads in history. With more than 25 individual projects feeding the upcoming architecture release, we have shaped a finely tuned Ethernet stack that will serve as a solid foundation for everything that follows.

The momentum is undeniable, and it is a direct result of the working group chairs, draft authors, and volunteers. On behalf of the steering committee, thank you.

Looking ahead

The future of the foundation is bright. As always, our culture encourages collaboration, collegiality, and cross-pollination of ideas across the Ethernet ecosystem. I challenge each of you to help us reach these goals.

In closing

To everyone involved since the beginning, my deepest gratitude. Your work and dedication brought us here, and we are positioned for even greater things in the months ahead. Thank you for your continued support as we work together to make NoLimit the premier networking standard for AI and HPC.

Best regards,
Everett Caldwell
