Features

Benefits

Junos Node Slicing

Converges multiple concurrent network functions on a single chassis to accelerate service deployment, reduce capital outlay, and improve

operational efficiency.

Seamless integration with a wide range of open-

source automation frameworks

Enables implementation of a DevOps approach to automate complex network operations and business- critical services.

Juniper Extension Toolkit (JET) API

Offers a simple and programmable framework that provides open access to control, management, and data planes.

Junos Telemetry Interface (JTI) scalable

distributed network analytic engine

Streams accurate real-time network data, providing service assurance with enhanced visibility to identify, isolate, and resolve potential

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

Junos Continuity

Makes adding new hardware a plug-and-play, non-service impacting event, eliminating device reboots during network updates.

High Availability

Junos OS supports high availability (HA), enabling service providers

and enterprises to avoid extended maintenance windows and

prolonged service impacts. Junos Continuity eliminates the device

reboot and network OS upgrade typically required during the

installation of new hardware such as line cards. Junos Selective

Update allows users to apply a patch (hotfix) on an installed version

of Junos OS running on a Juniper device without any service

disruption.

Superior Performance

By supporting full symmetric multiprocessing (SMP), Junos OS

enables the operating system to utilize all CPU cores on the

Routing Engine. The result is a flexible, scalable, and powerful

network infrastructure with the multicore capabilities of the

networking devices.

Security

Junos OS incorporates many advanced security features that

minimize network vulnerability. The Secure Boot feature certifies

that Junos OS devices boot with only an authentic, untampered

version of the Junos OS. It also ensures that devices boot an image

that has not been tampered with. The built-in security features

provide a secured and trusted chain of software development,

safeguarding device integrity from factory to the branch site.

Specifications

Junos OS encompass a comprehensive set of automation features

and support for open-source framework and standard protocols.

Automation features and open-source support are available across

Juniper’s product portfolio, including the Juniper Networks MX

Series 3D Universal Edge Routers, PTX Series Packet Transport

Routers, ACX Series Universal Access Routers, EX Series Ethernet

Switches, QFX Series Switches, SRX Series Services Gateways, and

T Series Core Routers.

Junos Automation Scripts

Junos Automation Scripts consist of:

• Op-Scripts: Used to perform operational tasks on demand

• Event-Scripts: Used to instruct Junos OS to perform actions in

response to system events

• Commit-Scripts: Used to instruct Junos OS to perform actions

at or during commit time

• SNMP Scripts: Provide the flexibility needed to support

custom MIBs

Fast Programmatic Configuration (eDB)

A fast, ultra-low-latency database for programmatic configuration,

eDB resides on Junos OS to help with programmatic changes that

are verified and monitored externally. SDN controllers and external

applications alike can benefit from this fast channel to make control

and data plane configuration changes on devices running Junos OS.

gRPC

General-purpose remote procedure call (gRPC) is an open- source,

BSD-licensed HTTP/2 RPC framework developed and used by

Google to handle remote procedure calls. gRPC enables the easy

creation of high-performance, scalable APIs and microservices in

many popular programming languages and platforms.

HTTP(s)

HTTP is a protocol used for communication, usually with Internet

resources or any application with a Web browser client. HTTPs

enables communication over an encrypted connection.

Juniper Extension Toolkit

The Juniper Extension Toolkit (JET) is a next-generation solution

that makes programming Junos OS simple, flexible, and extensible.

JET is based on four fundamental components: JET APIs, Python,

JavaScript Object Notation (JSON), and Fast Programmatic

Configuration (or eDB).

JET APIs

JET offers a set of APIs that are consistent across any Junos OS

supporting JET. JET APIs are language-agnostic and can be

accessed by any programming language. Applications developed

using JET APIs are also binary-compatible and can be executed

across any platform running a Junos OS release supporting JET.
