EdgeOS: Ubiquiti network operating system for routers and switches

Introduction

In today's business and service provider networks, a robust, flexible and low-cost operating system is essential to ensure infrastructure performance and security. EdgeOS, developed by Ubiquiti Networks, has been positioned as a Linux-based solution that combines the power of a grade-carrier operating system with an intuitive management interface. This post explores in detail what EdgeOS is, its main features, architecture, cases of use and how it can benefit network administrators and IT professionals.

What is EdgeOS?

EdgeOS is the operating system that drives the devices of the EdgeRouter and EdgeSwitch series from Ubiquiti. It is based on the Vyatta distribution, in turn derived from Debian Linux, and provides a complete routing environment with support for advanced protocols such as BGP, OSPF, RIP, MPLS and VPN IPsec / SSL. Unlike the operating systems owned by many manufacturers, EdgeOS offers access to the Cisco Junos command line (CLI), which facilitates the transition for engineers used to these environments.

Key features

• Advanced routing:It supports dynamic protocols (OSPF, BGP, RIP) and static, as well as rules-based routing policies.
• Integrated security:Firewall static, VPN IPsec and SSL, basic intrusion detection and filtered content.
• Quality of service (QoS):Priority lines, spinning and policing to optimize the traffic of voice, video and data.
• Consolidated management:HTML5 and CLI-based web interface complete, with scribing support using Bash and Python.
• Escalability:From small office routers to carrier level devices capable of handling hundreds of thousands of packages per second.
• Updates and community:Regular releases, active package repository and a user community sharing scripts and configuration templates.

Underlying architecture

EdgeOS runs on a modified Linux kernel, with a control plane using Vyatta's routing suite. The data plane is based on the DPDK (Data Plan Development Kit) forwarding plane in the latest models, which allows high performance without relying exclusively on the general CPU. The separation between control plane and data plane improves stability and allows software updates without interrupting forwarding traffic.

Typical cases of use

• SMEs:EdgeRouter routers offer secure WAN connectivity, VPN site-to-site and bandwidth management at a reduced cost.
• Internet Service Providers (ISP):The EdgeRouter Pro and EdgeRouter 12 models can act as BRAS or aggregation routers, supporting BGP and MPLS for layer 2 and layer 3 services.
• Educational and laboratory environments:The ease of installation and compatibility with simulation tools make EdgeOS a popular option for network practices.
• IoT and edge computing implementation:The ability to run Docker containers or custom scripts allows you to process data near the source.

Advantages against proprietary alternatives

• Zero license cost:There are no subscription fees; the only cost is hardware.
• Transparency and personalization:By being Linux-based, administrators can modify scripts, add Debian packages and create custom solutions.
• Low learning curve for Cisco / Juniper professionals:CLI follows a structure similar to Junos, which reduces training time.
• Frequent updates and community support:Monthly launches include security improvements and new features.

Comparison with other network operating systems

When EdgeOS is compared to systems such as Cisco IOS / XR, Juniper Junos or MikroTik RouterOS, some differences stand out:

• Cost:EdgeOS is free in terms of license, while IOS and Junos require expensive licenses.
• Flexibility:The possibility of installing Debian packages provides flexibility that owner systems do not match.
• Performance:In comparable hardware, EdgeOS and RouterOS offer similar performance, although Junos can have an advantage in scalability of carrier-grade.
• Ecosystem:Cisco and Juniper have an extensive hardware ecosystem and professional support; EdgeOS is more dependent on the community and Ubiquiti distributors.

First steps with EdgeOS

To start working with EdgeOS, follow these basic steps:

1. Download the latest image from the Ubiquiti site and record it on a microSD card or a USB based on your router model.
2. Connect the device to your management network and access the default IP address (usually 192.168.1.1) via a browser.
3. Use the initial configuration wizard to define the WAN, LAN, admin credentials and basic services such as DHCP and DNS.
4. Explore the CLI using SSH or console to configure advanced protocols (OSPF, BGP, VPN).
5. Save the configuration and make a regular backup by the commandsaveor through the web interface.

Best management practices

• Keep the system up to date: subscribe to the launch announcement and apply security patches monthly.
• Segments traffic using VLans and applies firewall policies specific to each area.
• Use the remote log (syslog) to centralize logs and facilitate audit.
• It implements two-factor authentication (2FA) for SSH access and web interface where possible.
• Documents all changes with a version control system (e.g. Git) by saving the configuration files/etc/config/.
• Monitor CPU and memory using tools likeshow system resourcesand sets alerts when critical thresholds are exceeded.

Conclusion

EdgeOS represents a powerful and cost-effective option for those looking for a network operating system that combines the robustness of grade solutions with Linux flexibility. Its wide range of features, from dynamic routing to VPN and QoS, makes it suitable for various scenarios, from small offices to service providers. By adopting EdgeOS, managers can reduce operational costs, increase customization capacity and keep up with an active community and frequent updates. If your infrastructure requires a router or switch able to grow with your needs without tying to expensive licenses, EdgeOS deserves serious consideration.
