T-O-F Latency Measurement System | LDA Technologies

Benefits

Note:

* Five nanoseconds, is 4.5 nanoseconds when the client-side interface clock is running faster than 500 Mhz. ** The client-side interface clock is asynchronous and can be as low as 322 Mhz

LightSpeed V2 consists of an LDA TCP Agent library running on a server with a Solarflare™ Onload-enabled adapter and FPGA-based TCP Offload IP cores. The agent library manages TCP sessions, while the offload cores leverage the FPGA’s capabilities for ultra-fast packet delivery.

This product contains technology proprietary to LDA Technologies and patented technology from AMD Solarflare™ (US patents: 9003053, 9600429, 9258390, 9456060).
