Broadcom has commenced shipments of its Jericho4 ethernet fabric router, a specialized platform crafted for the burgeoning demands of distributed artificial intelligence infrastructure. The Jericho4 is engineered to interconnect more than one million XPUs over several data centers, marking a significant leap over traditional scaling limitations with an emphasis on bandwidth, security, and truly lossless performance. This release positions Jericho4 as a core component in Broadcom´s broader portfolio, which also includes the Tomahawk 6 and Tomahawk Ultra chips, targeting high-performance computing and artificial intelligence networking.
The exponential growth of artificial intelligence models, both in size and complexity, is rapidly surpassing the constraints of individual data centers—driven by power, cooling, and physical infrastructure limits. To meet this challenge, compute resources must now be distributed across facilities, each drawing anywhere from tens to hundreds of megawatts. Such scale creates an unprecedented need for new classes of routers that blend extremely high throughput with robust, secure, and lossless transport over distances spanning multiple sites and even regions.
The Jericho4 aims to address these challenges with its 51.2 Tbps of aggregate bandwidth and advanced security features, including 3.2 Tbps HyperPorts for ultra-fast connectivity. Its architecture is specifically designed to overcome scaling bottlenecks and eliminate network loss—even under the pressures of interconnected, high-throughput artificial intelligence workflows. With this launch, Broadcom reinforces its intent to provide comprehensive hardware solutions for the evolving landscape of distributed computing in artificial intelligence and high-performance computing environments.
