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

Virtualization and Cloud Adoption –looking at ways to better utilize resources and embrace new architectures to achieve greater flexibility and scale.
Mobility – need to keep up with exponential demands and opportunities created by mobile adoption; mobile data growth rates exceeded 800% in 12 months. (Cavell)
Visibility and Control – need to understand and manage, in detail, their user’s behavior to create more accurate forecasting and more efficient content distribution strategies.

Let’s Look at Some Use Cases Being Deployed Now…
Why SDN Is Used
Accommodate Self-Service L4-7 Service Selection
To Create Dynamic Chains of L4-7 Services on a Per Tenant Basis
Accommodate Policy-Based L4-7 Service Selection (e.g. Turning on DDoS Protection in Response to an Attack or DPI in Mobile WAN
environments)
BenefitsReduced Provisioning Times: from
Weeks to Minutes
Improved Agility
Self-Service Supports New Revenue and Service Opportunities, with Substantially Lower Costs for
Service
Data Center/Service Provider DMZ/WAN – Service Insertion

Why SDN Is Used
Replace Existing Customer Premises Equipment (CPE) with
Lightweight Versions – in Combination with NFV Initiatives
Move Common Functions and Complex Traffic Handling into
Points-of-Presence (POP) or the Data Center
Benefits
Increase Usable Lifespan of On-Premise Equipment
Improve Troubleshooting: Less Truck Rolls
Flexibility to Sell New Services to Business and Residential
Customers
Virtual Edge (Residential and Business) – On-Premise Upgrades
11Copyright 2013. All Rights Reserved.
Why SDN Is Used
Enable Programmatic Controls on Carrier Links to Request Extra Bandwidth When Needed (e.g. Disaster Recovery; Backups)
Benefits
Reduced Operational Expenses: Allowing Customer Self-Service
Improved Agility: Saving Weeks of Manual Provisioning
Bandwidth on Demand

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
Edge – Dynamic WAN ReRouting

Why SDN Is Used
Create Dynamic Interconnects at Internet Exchanges
Between Enterprise Links or Service Providers Using Cost-Effective, High-Performance
Switches
Benefits
Reduce Operational Expenses: Ability to Instantly
Connect and Enable Self-Service Reduces Time and
Effort Associated with Creating Cross-Organization
Interconnects
WAN – Dynamic WAN Interconnects
