Next-Generation Routing for the AI Era
Broadcom has announced the release of its Jericho4 ethernet fabric router, a breakthrough platform engineered to power next-generation, distributed
AI infrastructure across vast data center environments[1][2][4]. With data centers increasingly encountering scaling limitations as artificial intelligence models and workloads become larger and more interconnected, Jericho4 stands out by enabling seamless, high-speed interconnections between over one million XPUs (accelerators such as GPUs and TPUs) distributed across multiple locations[1][2].
Unmatched Bandwidth and Lossless Performance
Jericho4 delivers 51.2 Tbps deep-buffered Ethernet, designed for lossless, low-latency networking that is optimized expressly for AI workloads that must span racks, clusters, and geographically separated facilities without compromising performance or reliability[2]. Each Jericho4 system can scale up to 36,000 HyperPorts, operating at 3.2 Tb/s per port, with deep buffering to support demanding
AI workloads and lossless RoCE (RDMA over Converged Ethernet) transport over 100 kilometers or more[1][2].
Key Features and Differentiators
- HyperPort Technology: Consolidates four 800GE links into a single logical port to reduce load balancing inefficiencies and maximize network utilization by as much as 70%
- Deep Buffering: Ensures zero data loss during congestion events, which is critical for distributed AI computation[1][2]
- Line-rate Security: Features line-rate MACsec encryption for maximum data security across long distances
- Advanced Congestion Control: Intelligent congestion management enables lossless RoCE transport across metropolitan and regional networks[1][2]
Enabling the Future of Distributed AI Infrastructure
As
AI models push the boundaries of what's possible, the need to interlink data centers—each drawing tens or hundreds of megawatts of power—has grown urgent. Jericho4 is designed to address these unique challenges by optimizing for massive scale and distributed environments rather than the confines of single-location infrastructure[1][2][4].
Ram Velaga, Senior Vice President and General Manager of Broadcom’s Core Switching Group, highlighted that the Jericho4 family unlocks the potential for scale-out Ethernet fabrics, supporting continuous, low-latency performance for distributed
AI clusters spanning vast geographic distances[2].
Market Impact and Strategic Momentum
Broadcom's AI networking technologies, including its Jericho routers, have solidified its position as a leader in the evolving data center networking space, supporting the world’s largest
AI clusters used by partners like Alphabet, Microsoft, and Meta[3]. The company is rapidly expanding its influence, with management projecting over 1 million AI chip clusters deployed by 2027 and strong financial performance driven by explosive AI segment growth[3].
