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 Definition1. 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

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

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

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
BenefitsSimplified 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

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

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
BenefitsSavings: 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
