ExaNIC X10-HPT
DUAL-PORT 10GbE NIC, WITH HIGH PRECISION TIMESTAMPING TO 250 PICOSECOND RESOLUTION
The ExaBlaze ExaNIC X10-HPT is the world’s first network interface card capable of timestamping Ethernet packets to sub-nanosecond resolution. Packets can be captured at line rate, with the arrival time of the first bit of each packet recorded with a granularity of 250 picoseconds.
For clients at the forefront of the latency race, this technology provides invaluable new insights. For example, the precise latency of a network device can be determined for each input packet – even for very low latency devices – rather than relying on statistical averages or vendor claims.
