How it works

Kernel Bypass

The traditional approach using Operating Systems network paths, will cause delayspacket drops and jitter. As network speeds continue to grow, kernel bypass for best performing network communication is a must have.


Performance Gain

  • Millions of packets. No Drops. Lowest Jitter

  • Zero Copy || Low CPU overhead

  • Sub microsecond latency.

What's new

New GigE Vision SDK release

  • GenTL consumer integration

  • Leverages Rivermax (TM) Technology by NVidia 

New: ExaNIC X25 25GbE support is here. Stays with the facts of

  • Dropless 

  • Linerate

LIBFSOCK-Proxy Release:

​With the concept of proxy and providers, multi vendor support at application level is achieved.

New: Native tcpdump and Wireshark support for Linux/Windows is here: 

  • Nanoseconds Resolution

  • libpcap/ WinPCap integration

You got a LINERATE play with 

  ---- exanic-replay ---- 

exanic-replay.exe -i 10 -m capture.pcapnp

Reading packets into memory

Read 13000 packets into memory 

Thread 0> Packets: 130000

Thread 0> Skipped Packets: 0 Thread 0> Bytes: 662360000

Thread 0> Rate: 0.21 Mpps

Thread 0> Throughput: 9.382 Gbps in 5.648 secs

Transparent acceleration/API

Choose from binary compatibility using a transparent acceleration mode or tailor your solution by modest changes to the communication layer.

Unique Features

  1. First PTP Grandmaster and Slave Configuration using Hardware based timestamps on Windows

    • Accuracy of a few nanoseconds only​ (Requires Server 2019)

  2. First IP Solution to sink at line rate, no packet drops (any Windows platform)

  3. First ​IP latency solution to break the 1us barrier (any Windows platform)

  4. Supporting 1, 10, 25, - 100GbE - today


Speeds and 


If you think 10GbE is just good enough for you, how about 25GbE or even 100GbE ?

As speeds grow, your timing resolution needs to grow as well. Learn more about high  resolution timestamping in pico seconds


As an independent software vendor (ISV), we have partnerships with various leading vendors.

Some of our solutions come as a bundle.

Featured Product:    FastSockets


Non-kernel bypass via sockets is coming short on high message rates and bandwidth.

Get ready for networks beyond 1GbE !


Our team consists of individuals with a passion on everything related to best in class performance. With a track record of more than 25 years experience, starting in the early 90's with research and application development on parallel computers such as Intel Paragon, Thinking Machines CM-5, Parsytec Gcel-1024, to being contributors to the middleware layers of the largest supercomputers in the world and network interface designers, we conclude that as of today we have a reputation to lose. 

With our innovative and insightful technology, we strive to enhance our users’ every day experiences. Founded in 2020, our incredible team of engineers and programmers have worked tirelessly to bring NEIO Systems, Ltd (f to the forefront of the industry as an Independent Software Vendor (ISV). One of our initial achievements was the delivery of the ExaNIC on Windows Drivers, a dropless 10/25GbE packet capture solution, achieving the lowest latency on Windows with sub microseconds latency. With our GigE Vision SDK we bring zero copy data transfers from Cameras supporting Machine Vision with ZERO CPU load.

We will continue to work relentlessly to become the technological standard, providing big picture insights and solutions for companies of all sizes. Get in touch to learn more.
