Broadcom has began transport the Jericho4 Ethernet cloth router, which has been engineered to help next-generation distributed AI infrastructure throughout knowledge centres.
In response to Broadcom, the product facilitates the interconnection of a couple of million XPUs by overcoming conventional scaling constraints with superior bandwidth, safety, and efficiency.
Jericho4, alongside Tomahawk 6 and Tomahawk Extremely, types a part of Broadcom’s networking portfolio designed for high-performance computing and AI.
Broadcom said that the rising complexity of AI fashions calls for infrastructure past a single knowledge centre’s capabilities. Distributing XPUs throughout a number of websites necessitates routers optimised for high-bandwidth, safe transport over intensive regional distances.
The Jericho4 system scales to 36,000 HyperPorts, every with a capability of three.2 Tb/s. That is facilitated by deep buffering, line-rate MACsec, and distant direct reminiscence entry over Converged Ethernet (RoCE) transport throughout distances exceeding 100km.
Broadcom’s HyperPort expertise consolidates 4 800GE hyperlinks into one logical port to enhance utilisation and streamline site visitors circulation, growing effectivity by as much as 70%. The Jericho4 is alleged to make sure lossless RoCE over prolonged distances by way of clever congestion management and deep buffering, thereby assembly the calls for of distributed AI infrastructures with out energy or house limitations.
Incorporating MACsec encryption on each port at full velocity maintains knowledge safety between knowledge centres with out impacting efficiency, mentioned the corporate.
The machine is manufactured utilizing a 3nm course of and incorporates Broadcom’s superior 200G PAM4 SerDes, lowering part dependency and enhancing system reliability by way of decrease energy consumption.
Complying with Extremely Ethernet Consortium (UEC) requirements, Jericho4 facilitates interoperability with an ecosystem of UEC-compliant gadgets. This ensures seamless integration inside open Ethernet AI materials, mentioned Broadcom.
Jericho4 presents functionalities equivalent to built-in accelerators for service service administration, enabling management throughout vast space networks, which is essential for service networks. The machine helps scalable Ethernet charges and provides built-in encryption capabilities for safe off-premise connectivity.
The router is tailor-made for diverse environments like service networks, campus settings, and cloud purposes. Its superior options embody low-power excessive bandwidth reminiscence packet reminiscence that enhances site visitors buffering and ensures zero packet loss even in congested networks.
Additional increasing Broadcom’s choices, the Tomahawk Extremely swap started transport in July 2025. This product delivers a swap latency of 250 nanoseconds, achieves a throughput of 51.2 terabits per second, and helps as much as 77 billion packets per second.
