Broadcom Unveils Innovation, Launches Industry’s First On-Chip Neural Network Switch

Broadcom recently announced the launch of the Trident 5-X12 chip, which is equipped with a new NetGNT (Network General Neural Network Traffic Analyzer) on-chip neural network inference engine

NetGNT is different from traditional packet processing. It is able to work in parallel, enhancing standard packet processing pipelines. Traditional pipelines can only process one packet/path at a time, while NetGNT, as a machine learning inference engine, can be trained to identify various traffic patterns across the entire chip.

It is understood that the Trident 5-X12 chip has powerful software programming functions and on-site upgrade functions, providing a bandwidth of up to 16.0 Terabits/second, which is the two core components of the Trident 4-X9. times. In addition, the new chip also supports 800G ports, can directly connect to Tomahawk 5, supports 1RU data center ToR, and is configured with 48 200G downlink ports and 8 800G uplink ports

Trident 5-X12 Other key benefits include 25% lower power consumption per 400G port, adoption of Broadcom's 100G-PAM4 SerDes technology, and support for DACs and linear optics up to 4m. In addition, the chip supports the transition to next-generation CPU and GPU servers using 400G network cards, introducing NetGNT to enable new features and improve network efficiency and performance

The new chip also adds The enhanced telemetry function provides real-time in-depth understanding of network operations and provides more data support for training NetGNT. Meanwhile, Trident 5-X12 increases forwarding/policy scaling to support growing network sizes while maintaining legacy API compatibility with current Broadcom switch chips.

Trident The 5-X12 is fully programmable in the Network Programming Language (NPL), allowing field upgrades to add new telemetry, security and traffic engineering capabilities. NPL vs. current Trident 4 series compatible, this series has been widely used in customized switch applications independently developed by customers. In addition, Trident 5-X12 also supports enterprise-level SONiC and SAI, which can be quickly and seamlessly integrated into the data center operation framework, providing users with more flexible and efficient solutions.
