Broadcom’s Jericho3-AI: High-Performance Fabric for AI Networks

Broadcom has introduced Jericho3-AI, a high-performance fabric aimed at reducing the time it takes for artificial intelligence (AI) workloads to complete a task. Jericho3-AI offers features like congestion-free operation, flawless load balancing, Zero-Impact Failover, and ultra-high radix, making it a game-changer in the AI networking space. With AI usage set to surge in the coming years, Jericho3-AI will enable network administrators to manage the constantly growing workloads posed by AI demands.

Jericho3-AI delivers 40% less power per gigabit and provides 26 petabits per second of Ethernet capacity, almost four times as much as the previous generation, while also allowing for the lowest total cost of ownership (TCO). The fabric is designed to provide optimal load balancing, end-to-end traffic scheduling, congestion-free operation, and zero-impact failover capability, specifically for AI applications.

With the ability to grow connections to 32,000 GPUs, each with 800Gbps, in a single cluster, Jericho3-AI offers ultra-high radix, providing the fastest task completion times. The fabric is expected to deliver the highest performance while also providing the broadest ecosystem of hardware and software vendors and a great degree of flexibility in network topologies and deployment options.

Bob Wheeler, Chief Analyst at Wheeler’s Network, said, “Jericho3-AI offers a high-bandwidth, low-latency, and low-power choice for networks connecting tens of thousands of GPUs, revolutionizing the economics of building and maintaining AI clusters for this exciting new era.”

The launch of Jericho3-AI is a significant milestone in the AI networking space, according to Broadcom, as it provides the highest performance fabric for AI networks. Arista, which runs the Arista 7800R3 supporting the growth of AI workloads and network traffic at petabit scale, is also excited to collaborate with Broadcom and drive the AI revolution.
