The data center landscape is undergoing a seismic shift. Driven by the explosive growth of hyperscale cloud computing, artificial intelligence (AI) and high-performance computing (HPC), Ethernet speeds are accelerating beyond 800G to 1.6T and even 3.2T. This evolution is fueled by breakthroughs in optical connectivity and the adoption of advanced silicon nodes (3 nm and 2 nm), enabling pluggable optical modules that support applications from short-reach (less than 10 km) to long-haul (greater than 500 km).

As Ethernet scales to Terabit speeds, the need for robust, low-latency and power-efficient security solutions becomes paramount. Traditional security architectures based on acceleration struggle to keep pace with these performance demands, creating a critical need for MACsec/IPsec solutions that can be integrated into Ethernet ports and operate at full line-rate across multiport and multi-rate environments.
The Rambus Multi-Channel Engine MACsec-IP-364 (+363) is purpose-built to meet the demands of next-generation Ethernet. It delivers full line-rate MACsec and optional IPsec support for 1.6T and 3.2T Ethernet ports, offering a highly scalable and configurable solution for securing high-speed data traffic.
Key capabilities
The MACsec-IP-364 (+363) engine is ideal for a wide range of applications, including:
Its multi-channel architecture supports up to 64 ports, with pooled classification and transformation resources that optimize multiport designs. The companion MACsec-IP-363 classifier enables autonomous MACsec processing or can be paired with external classifiers for customized deployments.
Rambus provides a comprehensive integration package, including:
This ensures a smooth path from evaluation to deployment, backed by world-class support from Rambus MACsec experts.
As Ethernet continues its march toward Terabit speeds, security must evolve in lockstep. The Rambus MACsec-IP-364 (+363) engine delivers the performance, flexibility and scalability needed to secure the next generation of data center infrastructure — without compromising on latency, power or throughput.
