Increasing switch radix is a key part of solving today's network bottlenecks, but getting there requires solving a number of technical challenges.
Next week at #OCPSummit26, Eridu Distinguished Technologist Dan Biederman will be discussing the importance and challenges of precise time in high-radix network switches.
As switch radix increases, networking systems encounter new timing scenarios that are easy to overlook but increasingly important to understand. The topic takes on particular relevance as AI infrastructure demands flatter networks and higher radix to help AI systems scale.

If compute is being redesigned around AI, why is networking still based on the switch architectures and designs that were developed for cloud and SaaS? (Thread follows ⏬)
#AINetworking #AIInfrastructure
ALT Drew Perkins quote: “AI data center networking needs to be rethought from the ground up with a clean sheet of paper--you don’t get to an order-of-magnitude higher scale using off-the-shelf silicon.”
Training and inference clusters continue to scale rapidly in GPU count, memory bandwidth, and east-west traffic. At the same time, model architectures and AI-based workloads are driving ever more data movement between accelerators.
As clusters scale, conventional switch architectures require adding tiers. But more tiers mean more hops, more optics, more power, more latency, and more failure points between GPUs that need to communicate at extremely high rates.
Building a network switch that delivers the order of magnitude advance in radix and throughput that is needed for AI isn't possible by incrementally extending conventional technology.
It's a complex problem that involves solving interrelated challenges in silicon architecture, I/O, packaging, power delivery, optics, system design, and software at the same time. ⏬
Solve those challenges and the benefits compound--a high-radix switch enables flatter fabrics, larger single-hop domains, and fewer network stages across both scale-up and scale-out environments.
If AI compute is scaling by orders of magnitude, the network connecting it has to be designed from the ground up for the same trajectory.

What would it take to break out of today's limits to the size of scale-up domains, reaching thousands of GPUs in a single-hop domain?
If you're headed to OCP Global Summit in two weeks, join Eridu CTO Promode Nedungadi and @delosdata CTO & Co-Founder Dan Daly as they discuss an open architecture for building multi-rack, single-hop domains of over 5000 GPUs.
They'll present an architecture that shrinks collective-communication time, tightens token-generation tail latency, and lets a frontier model fit entirely inside a single domain.

Underutilized GPUs are one of the most significant obstacles to improving performance in AI model training. A recent session at @IEEEHOTI found that improvements in networking could increase GPU utilization by 38%, a significant improvement with a direct impact on training performance, scalability and cost.
Thread with more information follows.
#AInetworking #HotInterconnects2026
ALT A comparison of GPU utilization, showing 64% for a baseline 230T switch and 88% for a Petabit switch, highlighting a 38% improvement.
The scenario: researchers from Turbalance and Lawrence Berkeley National Laboratory ran a deep simulation of the impact of a 1 Pbps network switch on training time for a frontier mixture-of-experts AI model, comparing it to a baseline scenario using a hypothetical 230 Tbps switch.
The training workload: a ~20T parameter MoE model derived from Llama 4 Maverick, with 2,304 experts (16 active).
The approach: Turbalance's trace-driven, discrete-event simulator whose flow-level backend models point-to-point traffic for every collective.
Their results for a maximum expert parallelism scenario:
📊 38% improvement in GPU utilization--from 64% to 88%
⚡ 4.5x faster all-to-all collectives
📈 27.5% faster job completion time
Those results demonstrate how important the network is for training--not only for training performance, but also because it impacts cost and scalability of the infrastructure needed to support training.
That's why Eridu is focused on delivering an order-of-magnitude advance in radix and throughput with a purpose-built network switch that has been designed from silicon to system for the demands of AI. eridu.ai

What will it take to address the rapidly-increasing pressure on the back-end networks that are critical to AI clusters?
A great panel of industry experts from Open Compute Project Foundation, 650 Group and Eridu dove into that topic recently, looking at the growing challenges in networking that result from the exponential growth of AI.
➡️ Why conventional switch architectures are hitting a “network wall” as GPU clusters grow
➡️ Why scale-up networks are moving beyond a single rack toward larger, multi-rack domains with optical interconnects
➡️ What technology innovations are needed to make an order of magnitude advance in switch performance and scale
➡️ How higher-radix switching can create flatter networks with fewer hops, less complexity, and more efficient use of infrastructure
