First, Let’s Define SDN


SDN is a New Way to Design, Build and Operate Networks

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

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


Why Are Service Providers Interested in SDN?


They Want to Drive Down Costs and Monetize their Networks

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.

So, What Are Service Providers Doing with SDN?


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


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
