SDN & Agile Controller DCN
Geoff Tayler
18th June 2016
What is SDN ?
The physical separation of the network
control plane from the forwarding
plane, and where a control plane
controls several devices
Software-defined networking (SDN) is an umbrella
term encompassing several kinds of network
technology aimed at making the network as agile and
flexible as the virtualized server and storage
infrastructure of the modern data center
Software-defined networking (SDN) is an
approach to computer networking that
allows network administrators to manage
network services through abstraction of
lower-level functionality.

The goal of Software-Defined
Networking is to enable cloud and
network engineers and administrators
to respond quickly to changing
business requirements via a
centralized control console.
Software defined networking (SDN) is an approach to
using open protocols, such as OpenFlow, to apply
globally aware software control at the edges of the
network to access network switches and routers that
typically would use closed and proprietary firmware

• Long Time to Market
• Hundreds of adjustment / day
• Hard to troubleshoot

What Can It Do ?

Cloud management provides
application definitions (the “defining”
software).
Agile Controller DCN provides for
network policies to be applied to
Applications
Policies are processed to generate
logical topologies
Agile Controller DCN maps logical
Topologies to Physical Network
This remains true even when
workloads are migrated, potentially
even between physical Datacentres

The service management platform converts the
application framework into a logical network.
Logical Network
The controller maps logical networks into
physical networks and delivers services.
