Welcome to Cumulus Networks

We are transforming networking with Cumulus Linux, the industry’s first, full-featured Linux operating system for networking hardware. Cumulus Linux is a complete network operating system, based on Debian wheezy. Unlike traditional embedded platforms, Cumulus Linux provides a complete environment pre-installed with scripting languages, server utilities, and monitoring tools. Management tasks are accomplished via SSH using standard Linux commands or over a serial console connection.
