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

Junos Space Centralized, Automated Network Management

• Extract services from network and

security devices by creating

service VMs

• Leverage cost and sourcing

advantages of x86 servers

• Enable dynamic scalability and

enhanced service agility

• Leverage existing investment in

the Mx to offload services to the

Mx, while running these services

on x86

Applications

• Centralize controller to have a

broad view of the network and

holistically optimize traffic flow

• Service chaining enables multiple

network and security services to

dynamically connect in series and

be inserted into traffic flows

• Increase network agility and

decrease provisioning time

• SDN controller is logically

centralized but can be physically

distributed
