ENABLING NETWORK AUTOMATION

WITH JUNOS OS DATASHEET

Product Description

The market environment is transforming. Increasing dependence on cloud-native

applications, the continued growth of geographically distributed data center and branch

offices, and the emergence of Internet of Things (IoT) and 5G technologies have all placed

significant demands on the networking environment, driving the need to simplify

configuration, integration, and management. Service providers and enterprises require an

operating system that automates network processes, streamlines service deployment, and

analyzes real-time network data consistently across a diverse and growing number of

network devices and geographical locations.

Juniper Networks® Junos® operating system is the single network OS that powers Juniper’s

broad portfolio of physical and virtual switching, routing, and security products. Built with

open programmability and an intent-based automation framework as the core principles,

Junos OS is the first modular network operating system that provides clear separation

between control, management, and data planes. It is also the first network OS with open

interfaces, versatile scripting support, and open-source frameworks, enabling service

providers, enterprises, and developers to implement a DevOps approach that automates

complex network operations to improve service agility.

Featuring a modular design, Junos OS includes Junos Node Slicing, a market-leading

innovation for virtualization and optimization. By decoupling network software from the

underlying network infrastructure while allowing control, management, and administration

isolation, Junos Node Slicing enables the convergence of multiple concurrent network

functions on a single chassis, maximizing network utilization while creating segmented

services for customer satisfaction.

Architecture and Key Components

Junos OS consists of the following key automation components:

• Automation Frameworks: Junos OS supports a wide range of open-source

automation frameworks, including Puppet, Chef, Ansible, and Salt. This allows the

seamless integration of Junos OS-powered network devices with network systems

management infrastructure. Junos OS also supports PyEZ, a micro framework for

Python developed by Juniper, which enables remote automated device management.

• Programmability: The Juniper Extension Toolkit (JET) API is a simple framework

providing seamless programmability access to control, management, and data plane

services via a rich set of APIs. Decoupled from Junos OS releases, the JET API is

consistent across the entire Juniper portfolio regardless of Junos OS devices or an

external server attached to a Junos OS device.

• Telemetry: Junos OS incorporates Junos Telemetry Interface (JTI), a highly scalable

distributed network analytic engine designed to gather, aggregate, and stream

accurate, real-time network data and event states. JTI delivers the required enhanced

visibility into the network to identify, isolate, and resolve potential issues based on

real-time network statistics and events with minimal human interaction.
