Broadcom ships single-chip 25.6-Tbits/s router

Broadcom is now shipping the next-generation of its StrataDNX family of single-chip routers. The new Qumran3D single-chip router targets carrier and cloud service providers facing bandwidth, subscriber and services growth.

The Ethernet switch router chip, claimed as the industry’s first built on 5 nm, offers 25.6 terabits per second (Tbits/s) of routing in a fixed form factor. A routing solution, using a single Qumran3D, is expected to save up to 66% more energy and 80% more rack space than previous generations, according to Broadcom.

Delivering a high-performance, low-power and security-rich networking solution , the Qumran3D meets bandwidth and security requirements driven by AI, mobile edge and other high-data deployment, Broadcom said. Applications include core, edge, peering and DCI routers, as well as aggregation systems.

Features include high-speed, high-density port interfaces up to 800GE; a processing pipe addressing any carrier and cloud requirements and futureproofing via Elastic Pipe; carrier-grade hierarchical traffic manager, HBM packet memory and massive on-chip forwarding databases that eliminate the need for companion devices.

Another key feature is dedicated on-chip processing and buffering, with large-scale forwarding, strong security and native line-rate MACsec encryption on all ports. The embedded forwarding databases meet the required scale for any routing environment, with sufficient headroom for continued growth of subscribers and services in the coming decade, according to Broadcom.

In addition, the company reports that theQumran3D’s 256 links of 100G PAM-4 SerDes enable a 25% to 50% reduction in the optical transceivers’ power consumption for the cluster interconnect using linear drive optics. It also supports emerging 800ZR+ optics for DCI and IP over DWDM.

On the security front, the router’s large-scale on-chip policy tables provide privacy and protection to the network and its subscribers. Flexible policy engines, IPsec for connection security and MACsec for line-rate encryption deliver protection to subscribers with millions of private connections, without a performance compromise, Broadcom said.

Broadcom is currently shipping Qumran3D devices to qualified customers.
