Open Networking

What is Open Networking?

Open Networking is to network devices what Windows or Linux is to computers. Just as these operating systems transformed how we use computers, Open Networking revolutionizes the way we manage network switches and routers. It brings the principles of openness and customization to network infrastructure, allowing more flexibility and innovation in how networks are designed and operated.  

Using Open Networking isn’t about learning something completely new; it’s about applying what you already know about networks in a more flexible way. It’s like learning a few new tricks on a system you’re already familiar with. So, if you understand the basics of networking, adapting to Open Networking is straightforward. It’s not a big leap; it’s just a new, smarter way to handle your network devices, offering more customization and efficiency.

What does Open Networking give you? You win independence as you can choose your hardware switch and router vendor independently. You win full control as the operating system can be tweaked to whatever you like it to be. You win the possibility to add your own tools, programs and develop your network to be as efficient as you wish it to be.

You gain a community and become an innovator, enabling you to collaborate on forward thinking ideas and business concepts for a brighter future.

With Open Networking, you achieve freedom,

and freedom is the only way to do it better.

So let’s make it better, together!

The Open Networking Software

Choose from a range of Network Operating Systems and Software Tools – from Open Source to Commercial Solutions.

One of the most important advantages of Open Networking is the switch adapting to different roles by simply changing the switch operating system and software tools. Sometimes, Windows is the best choice but sometimes, you might prefer Linux.

  • Did you know that Open Networking is using Linux based Operating Systems for Layer 2?

  • Did you know that Open Networking is using Linux based Operating Systems for Layer 3?

  • Did you know that you could build a Network Packet Broker on the same Hardware?

  • Did you know that Open Networking Operating Systems mostly use modern Container based Designs?

  • Did you know that you have the choice to configure your Open Networking Switch without any Linux experience? Simply use an industry standard CLI that you know already.

  • Did you know that you will get a unified management framework with modern API Interfaces like REST, GNMI, CLI, Shell? This will ensure that no matter which method you choose to configure your switch, you will always get the same result.

  • Did you know that Operating System Support is available 24x7?

  • Did you know that you could add your own containers to extend the network stack capabilities yourself?

  • Did you know that you could build your own applications and add-ons yourself (monitoring, DHCP etc.)?
