Exablaze's ExaNIC X10 is an ultra-low latency network interface card which delivers low latency: 780ns application to application for small Ethernet frames (using the native API) and under a microsecond for small TCP and UDP payloads (using the transparent socket acceleration library). The ExaNIC X10 also has built-in bridging functionality which allows it to function as a miniature switch, avoiding the extra latency of a switch in some common use cases. Additionally, with hardware-based time stamping of every packet to 6 nanoseconds resolution, users can rethink their approach to measurement and latency management. The card features an SMA connector which can accept a PPS in or drive PPS out to further improve the accuracy of timestamps taken throughout the system.
