Who we are

Cumulus Networks is leading the transformation of bringing open, web-scale networking to organisations of all sizes. Cumulus Linux is an open network operating system for bare metal switches based entirely in Linux.

Cumulus Networks boasts flexibility, efficiency, speed and choice by unifying the stack with Linux. Instead of focusing on siloed solutions Cumulus Networks transforms every stage of the networking lifecycle including architecture, design, build, deployment and operations.


Cumulus Linux

Flexibility and customisability enable networking teams, no matter how large or small, to operate at the scale of cloud giants such as AWS, Microsoft and Google.


NetQ is a telemetry-based fabric validation system that gives you complete visibility and actionable insight from host to switch.

NetQ reduces network management complexity, dramatically improves network uptime, greatly enhances network agility and is a critical step along the journey to intent-based networking.

This modern management system upgrades network operations from a manual, reactive, box-by-box process to an automated, informed and agile one.

Our Advantage

Lower TCO

With Cumulus Networks, companies can reduce CapEx by 45% and OpEx by 74%.

What’s the Increased efficiency

By leveraging solutions such as Zero Touch Provisioning (ZTP) and automation tools (including Ansible, Puppet and Chef), network operators can drastically save time by automating configurations and operations.

These automation capabilities not only save time and enable rapid deployment, but they also reduce network downtime since the lack of manual intervention prevents network errors.

You can now increase the ratio of switches per network operator, allowing your company to grow exponentially and operate at the scale of cloud giants (no matter how big or small your networking team is).

Freedom of choice

Your network’s possibilities don’t have to be limited by proprietary vendors’ decisions.

With 70+ compatible hardware platforms, complete access to the Linux kernel’s offerings and multiple applications to choose from, your network’s design is in your hands.

Complete interoperability

With Cumulus Networks, you’re working with Linux throughout the entire stack. It can integrate with tools and solutions the network team is already using – the same tools that you use elsewhere in your data centre stack can be leveraged within the network since it’s just Linux.

Reduced network errors

Increased automation leads to decreased manual configuration, which means fewer errors in your network.

Cumulus Networks also focuses on creating simplified operations, decreasing room for error and making life easier for networking teams. Zero Touch Provisioning (ZTP), Network Command Line Utility (NCLU), stack unification through Linux and other features keep the network running as intended.

How does our solution work?

  • Ethernet Virtual Private Networks (EVPN) free from layer 2 complexities operates over layer 3 networks.
  • Network Command Line Utility (NCLU) for easy network configuration and operation.
  • OSPF Unnumbered automated configs no longer depending on unique IP addresses.
  • Prescriptive Topology Manager (PTM) verifies connections faster.
  • Virtual Routing and Forwarding (VRF) multiple network paths without switches
  • Lightweight Network Virtualisation (LNV): controller-less VXLAN deployments.
