Services and Applications are Moving to
the Cloud, infrastructure is not elastic
Virtualization has Automated Compute

TO IMPROVE BUSINESS AGILITY
Need to create and deliver revenue opportunity faster and control cost
Connecting Networks, Clouds, VMs
Remains a Very Manual Process.

LIMITATIONS OF CURRENT APPROACHES TO NETWORKING IN THE CLOUD
ORCHESTRATION Lack of networking capabilities in orchestration stacks
AGILITY Physical limitations to how services are deployed and connected.
AUTOMATION Manual service provisioning and upgrade with appliance centric model
SCALABILITY Traditional solutions limit scale of the cloud.

Principles of SDN
6 GENERAL SDN PRINCIPLES
Separate networking software in 4 planes –
Forwarding, Control, Services and
Management
Optimize each network element
Centralize Management, Services and
Control planes Simplifies network design and lowers opex
Adopt Cloud for elastic scale and flexible
deployment, enabling usage-based pricing
Reduce time to services and correlates cost
based on value
Common Platform for network and security
applications and management integration Enables new business solutions
Standard protocols for interoperability across
vendors
Provides choice and lowers cost through
interoperability
Broadly Apply to Network & Security, Enterprise
& Service Provider networks, Mobile & Wireline Flexibility and new business opportunities
Customer benefits
These are the guiding principles behind Juniper’s SDN vision & product roadmap.
