Broadcom Unveils Jericho4 Ethernet Fabric Router: Interconnects Over 1 Million Processors
Broadcom’s Jericho4 Ethernet fabric router interconnects distributed AI computing clusters across distances exceeding 100km, addressing AI compute bottlenecks. It supports over a million XPUs across geographically dispersed data centers, featuring a HyperPort interface with up to 36,000 ports and 3.2 Tbps bandwidth each. Jericho4 extends RDMA over Converged Ethernet (RoCE) support and integrates line-rate MACsec encryption. Adhering to UEC specifications and utilizing standard Ethernet packets, it simplifies integration and improves bandwidth utilization by up to 70%.
