“Any sufficiently
advanced technology is
indistinguishable from
magic” – Arthur C. Clark
Sometimes it’s too Easy
‘The downside of “Easy Button” is that
it usually doesn’t get considered
“Automation” because you don’t have
to do anything… go figure!’ –
Anonymous Juniper Engineer
What does SDN mean to you?
Gartner
SDN
1. a new approach to designing, building and operating networks that
focuses on delivering business agility while lowering capital and
operational costs. It is far more than just a new set of APIs
designed to replace command line interfaces for managing individual
devices.
2. a shift from (per box) element-based control to network-based
control.

Juniper Automation Heritage
Consistent feature development
From early on we have developed strong
automation features in the very heart of
our platforms, e.g.
•
Network OS
Junos V
Junos
Space
Chef
App Engine
Puppet
XML-RPC / Netconf / DMI
1996
•
Junos Scripting with Op, Event and Commit
Scripts
•
Space with Network Director and Security
Director for network level abstractions
•
Integration with Configuration and Cloud
Management Platforms, to enable end-toend automation
•
Junos SDK
Control

JunosEZ Framework for off box and on box
scripting and integration into existing
customer solutions

What is ZTP? (It’s Not Magic)
The Preboot eXecution Environment (PXE) is a standardized clientserver environment to boot clients from a network. Only a PXE capable
Network Interface Card and small set of protocols such as DHCP and
TFTP are required.
Consistency Matters
Analyst and Academic
research suggests That
70-80% of Networks
are
Vulnerable Due to
Configuration Errors.
Regular Audits for
Consistent Passwords
Non Blank SNMP Community strings
VLAN Consistency
Etc.
75%
The Junos Automation Stack
Tool built into Junos that enable automation
The Junos OS has had automation features consistently
added over the past 15 years.

This heritage of feature innovation has allowed Juniper to
deliver new features by building on top of the abstraction
layer below.

Junoscript
Three (3) key features form the basis for almost all
automation aspects at the platform layer
REST
CLI
jVision
Sensor
XML-RPC
Chassis

XML-RPC in the core of Junos and
Netconf to provide network based
access to the system

Junos Script for automating Operational,
Configuration and Event based tasks

Junos EZ Framework implementing
Python and Ruby based object models
for interacting with Junos using modern
programming languages
SNMP
RO
Data Plane (PFE)
Junos Platform Automation Stack
Scripting
Commit Script
Run every time a user commits the configuration, can
help with automation and consistency
Op Script
Initiated by an operator, help in
troubleshooting, configuration, monitoring
Event Script
Initiated by an event policy and allow
automation and troubleshooting

Automation – The Hard Part
• Not a technical problem, it is cultural
• Automation is business driven
• Intellectually difficult
• An engineer’s value is not how much they type at the keyboard
• Networks are already highly automated, if you think about it
• Nothing good is easy, nothing easy is good
