Broadcom recently unveiled the Jericho4 Ethernet fabric router, a cutting-edge platform designed to meet the evolving needs of distributed AI computing. This next-generation system is now available for commercial use, offering solutions to the scaling challenges faced by traditional data center networks. With the Jericho4, high-bandwidth, secure, and lossless interconnectivity can be achieved across geographically dispersed infrastructures, catering to the growing complexity and size of AI workloads.
In response to the increasing demand for distributed compute power in AI models, Broadcom has developed the Jericho4 as a game-changing solution. This innovative platform serves as a cornerstone for wide-area, Ethernet-based AI fabrics, facilitating seamless connectivity across various data center environments. With the capability to interconnect over one million XPUs, Jericho4 leverages Broadcom’s high-performance networking portfolio, including Tomahawk 6 and Tomahawk Ultra.
Jericho4 boasts impressive features such as 3.2 Tbps HyperPorts, which enhance bandwidth utilization by aggregating four 800GE links into a single logical port. This architecture significantly improves load-balancing efficiency and optimizes traffic flows across distributed environments. Additionally, the platform introduces critical innovations like deep buffering for reliable lossless Remote Direct Memory Access over Converged Ethernet (RoCE) and line-rate MACsec encryption for enhanced security under heavy traffic loads.
According to Ram Velaga, Senior Vice President and General Manager of Broadcom’s Core Switching Group, Jericho4 is specifically engineered to extend AI-scale Ethernet fabrics beyond the confines of a single data center. With its congestion-free RoCE support and advanced HyperPort capabilities, Jericho4 offers the performance required for distributed AI computing at a massive scale. Manufactured using a 3nm process and incorporating Broadcom’s 200G PAM4 SerDes technology, Jericho4 delivers high efficiency while minimizing the need for external components like retimers, resulting in lower power consumption and increased reliability across complex network setups.
Moreover, Jericho4 is designed for seamless interoperability, adhering fully to standards set by the Ultra Ethernet Consortium (UEC). This ensures easy integration into open, standards-based Ethernet networks, enabling compatibility with a wide range of network interface cards (NICs), software stacks, and switching equipment. By launching the Jericho4, Broadcom aims to establish itself as a leading technology provider for AI data centers grappling with the challenge of interconnecting massive compute resources across dispersed environments. With a fabric that scales seamlessly across geographic distances without compromising performance or security, Broadcom is addressing a critical bottleneck in the next era of high-performance distributed computing.
