Junos OS

Network operating system for routing, switching, and security

Simplicity and innovation—they’re what make Junos® operating system so unique. Junos OS is the common language running across our routing, switching, and security devices.

    Overview

    Junos OS is a reliable, high-performance network operating system for routing, switching, and security. It reduces the time necessary to deploy new services and decreases network operation costs. Junos OS offers secure programming interfaces and the Junos SDK for developing applications that can unlock more value from the network.

    Running Junos OS in a network improves the reliability, performance, and security of existing applications. It automates network operations on a streamlined system, allowing more time to focus on deploying new applications and services. And it’s scalable both up and down, providing a consistent, reliable, stable system for developers and operators. This, in turn, means a more cost-effective solution for your business.

    Junos OS is architected with DevOps in mind. With versatile scripting support and integration with popular orchestration frameworks, Junos OS offers flexible options for continuous delivery and DevOps style management. The Junos Continuity features further enhance continuous delivery and efficient software re-qualification.

    Software-Defined Networks (SDN)

    Junos OS provides programmability and controls for SDN through a rich set of protocols and application programming interfaces (APIs). SDN solutions enable automation and orchestration of highly scalable service provisioning alternatives giving service providers increased business agility and the power to create new offerings.

    Fusion

    With Junos Fusion, service providers can reduce network complexity and operational costs by collapsing underlying network elements into a single, logical point of control from Junos OS routing platforms. Junos Fusion is fully interoperable with third-party solutions and is extensible to SDN control.
