In Ethernet mode, the CN6000 can pair with switches from other vendors, including Broadcom’s Tomahawk line. Traffic sent over Ethernet still passes through an internal encapsulation layer built around Omni-Path. Spelman said that internal architecture preserves congestion management, credit-based flow control, and packet spraying, aimed at low latency and high message rates even when the wire protocol is Ethernet rather than Omni-Path.
“We have the Ethernet protocol inside the chip, it’s an encapsulation layer, and it races around the chip like an Omni-Path packet, and then it comes back out and is retranslated back out to Ethernet,” Spelman said. “So, you still get some of the benefits of the Omni-Path native architecture, even though on the wire it’s Ethernet.”
Putting compute inside the network
Active Compute Fabric extends Cornelis Networks’ combination of proprietary performance and open standards into scale-up networking. It adds a new element—compute embedded directly into networking silicon—in an approach that differs from the functions found in a typical smart NIC or DPU.
