Broadcom's Jericho4 Revolutionizes AI Networking in Data Centers

Broadcom Launches Jericho4 for Advanced AI Infrastructure

Broadcom Inc. (NASDAQ: AVGO), a leading name in semiconductor solutions, has introduced the Jericho4 ethernet fabric router, marking a significant advance in the field of distributed artificial intelligence (AI) computing. This innovative platform is designed to seamlessly interconnect over a million XPUs across various data centers, pushing beyond conventional limits associated with scaling, and offering exceptional bandwidth, security, and lossless performance.

Scaling Infrastructure to Meet AI Demands

As the sophistication of AI models escalates,, infrastructure demands are increasingly challenging the capabilities of individual data centers. The need for distributing XPUs across multiple sites, each capable of handling substantial power loads, calls for a new breed of routers. Jericho4 is specifically optimized for high-bandwidth transport, robust security, and lossless connectivity, capable of spanning regional distances effectively.

Technological Excellence of Jericho4

The Jericho4 family has been meticulously engineered to enhance Ethernet fabrics beyond the confines of single data centers. Ram Velaga, Senior Vice President at Broadcom's Core Switching Group, elaborates on its design, emphasizing the router’s ability to ensure congestion-free RoCE (RDMA over Converged Ethernet) and the support of a remarkable 3.2 Tbps HyperPort. These features make it pivotal in enabling expansive distributed computing systems that can operate fluidly across racks and multiple data center environments.

With the capability to scale to 36,000 HyperPorts, each rated at a staggering 3.2 Tb/s, the Jericho4 system is equipped with deep buffering, line-rate MACsec encryption, and RoCE transport over distances exceeding 100 kilometers, amplifying its utility for AI applications.

Enhanced Performance and Security Features

Broadcom's 3.2T HyperPort technology amalgamates four 800GE links into a cohesive logical port, eradicating inefficiencies found in load balancing, thereby improving utilization rates by up to 70%. This advancement not only conserves energy but also streamlines traffic flow across expansive fabrics.

Moreover, the Jericho4 architecture employs deep buffering alongside intelligent congestion control mechanisms, guaranteeing lossless RoCE across significant distances. This facilitates the creation of a truly distributed AI environment that is not hindered by power or space limitations found in singular locations.

In terms of security, Jericho4 supports MACsec encryption on all ports, ensuring the protection of data in transit between data centers without compromising performance—even during peak traffic loads. This significant feature underscores Broadcom's commitment to offering robust security solutions.

Field-Ready and Interoperable

Manufactured utilizing a cutting-edge 3nm process, Jericho4 incorporates Broadcom’s advanced 200G PAM4 SerDes technology, which is known for its impressive reach. This design reduces the need for auxiliary components like retimers, contributing to lower overall power consumption, cost efficiency, and enhanced system reliability.

Jericho4 is compliant with specifications set forth by the Ultra Ethernet Consortium (UEC), promoting seamless interoperability across open, standards-based Ethernet AI fabrics. This compliance facilitates smooth integration with a wide range of UEC-compliant network interface cards (NICs), switches, and software applications.

Availability and Future Prospects

Currently, Jericho4 is available for sampling to customers, signaling the dawn of a new era in AI networking.
