Supports full line-rate capture with High Resolution Timestamps (HPT). High-speed capture can be performed to both standard PCAPs (with nanosecond resolution) and enhanced PCAPs (with picosecond resolution) using the Exact Capture software. Timestamps are also delivered directly through intuitive C- and Python-based APIs.
Scalable and programmable
For demanding capture applications, load balancing automatically distributes flows across a collection of receive queues to make the most of CPU parallelism. For those who need more control, flow steering directs traffic to specified threads or cores based on programmable rules.
Industry-standard synchronization
The Cisco Nexus NIC HPT Pulse-Per-Second (PPS) input can be used to synchronize the HPT clock with a PPS source such as a Grand Master and/or GPS receiver to within 1ns, allowing users to meaningfully compare captured timestamps across multiple servers and/or geographic locations. The Cisco Nexus NIC HPT can also generate PPS output to master other devices in a rack and hardware assists Precision Time Protocol (PTP IEEE1588) packets for 2ns time synchronization across machines.
Ultra-low-latency performance
The Cisco Nexus NIC HPT is also an ultra-low-latency network interface card. Designed from the ground up to minimize latency, the Cisco Nexus NIC HPT delivers great performance.
Easy to use
The Nexus NIC HPT transparent socket acceleration library allows applications to benefit from the low latency of kernel bypass, in most cases without modifications to the applications. For the most latency-sensitive applications, a library allows for direct low-level access to the Nexus NIC hardware and includes simple functions for sending and receiving Ethernet frames.
