Virtualization and Cloud
Adoption – 60% of all
enterprises will have adopted
some form of cloud computing
in 2013 (Gartner), re-
engineering the way they
architect their infrastructure
and orchestrate the network
to deliver applications.
Cost Containment – there
is a big network component
to the consolidation and
optimization initiatives
undertaken to help scale
IT within budget.
Big Data – generating value
from all the enterprise data is
the challenge, and it’s only
going to get bigger (consider IP
Traffic alone is Growing at an
Annual Compound Growth Rate
at 29% through 2016 (Cisco
Visual Networking Index). The
network will need to be more
reliable, resilient and flexible.

SDN Definition
1. Separates the network’s control (brains)
and forwarding (muscle) planes
2. Provides a centralized view of the overall
network
3. Utilizes programmatic application
interfaces (APIs)
4. Enables efficient orchestration and
automation of network services

6. SDN Promises
Agility: enabling organizations to rapidly deploy
applications, services, and infrastructure to meet needs
Scale: automate and optimize new and existing
applications and services
Innovation: allowing organizations to create and deliver
new types of applications, services and business models
SDN Opens the Network Up for Innovation

It replaces static, inflexible and complex networks, with networks that
are agile, scalable and innovative.

SDN?

Let’s Look at Some Use Cases Being Deployed Now…

8. Why SDN Is Used
To Slice up the Network for
More Flexible Configurations
Dynamically Segregate
Topologically-Equivalent
Networks Across a Data Center
Scale the Network Beyond the
Typical Limits of VLANs
(approx. 4,000 today)
Benefits
Maximize Utilization of Data
Center Resources: 20-30%
Better Use
Faster Turnaround Times when
Creating Segregated Networks –
Automated APIs Can Be Used to
Create New Networks in Minutes
Versus Weeks
Data Center – Slice Up the Network in Virtualized
and/or Multi-Tenant Environments

9. Why SDN Is Used
To Create Location-Agnostic
Networks Across Data Centers
To Create Location-Agnostic
Networks Across Racks
To Leverage VM Mobility and
the Dynamic Reallocation of
Resources
Benefits
Simplified Applications Are More
Resilient, Without Complicated
Coding
Improved Recovery Times in
Disasters
Better Use of Resources, as VMs
are Transparently Moved to
Consolidated Workloads
Data Center – Stretch the Network in a Virtualized
Environment

10. Why SDN Is Used
Speed Troubleshooting
Gain Visibility
For Any Port in a Multi-Switch
Deployment, Without the Use
of Multiple, Expensive Network
Packet Brokers (NPB).
Benefits
Dramatic Savings: $50-100K per
24 to 48 switches in the
infrastructure
Cost Reductions: Less Overhead
in Initial Deployment, No Need to
Run Extra Cables from NPBs to
Every Switch
Data Center/Campus Access Networks – Gain
Visibility with Tap Aggregation

11. Why SDN Is Used
To Bypass Expensive Inspection
Devices When Moving Large
Amounts of Trusted Data
Provide Dynamic, Yet
Authenticated Programmable
Access to Flow-Level Bypass,
Using APIs to Network Switches
and Routers
Benefits
Savings: Hundreds of Thousands of
Dollars in Unnecessary Investment in
10Gbps or 100Gbps L4-7 Firewalls,
Load-Balancers and IPS/IDS that
process traffic.
Maximize Utility of Inspection
Devices: Focusing Them on Traffic
that Poses a Risk to the Network
Reduce Operational Expenses:
Automate and Orchestrate Delivery
Across All Resources
Edge – Dynamic WAN Re-Routing
