Software-Defined Networking (SDN) Use
Cases
How Service Providers Are Using SDN
© 2013 SDNCentral. All Rights Reserved. SDNCentral Confidential
First, Let’s Define SDN
© 2013 SDNCentral. All Rights Reserved. SDNCentral Confidential
SDN is a New Way to Design, Build and Operate
Networks
Copyright 2013. All Rights Reserved.3
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

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
Copyright 2013. All Rights Reserved.4
It replaces static, inflexible and complex networks, with networks that
are agile, scalable and innovative.
Why Are Service Providers Interested in
SDN?
© 2013 SDNCentral. All Rights Reserved. SDNCentral Confidential
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.

Reduce CAPEX and OPEX and Grow Revenue and ARPU
So, What Are Service Providers Doing with
SDN?
© 2013 SDNCentral. All Rights Reserved. SDNCentral Confidential
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)
Benefits
Reduced 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
10Copyright 2013. All Rights Reserved.
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
12Copyright 2013. All Rights Reserved.
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
13Copyright 2013. All Rights Reserved.
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

  • 3. SDN is a New Way to Design, Build and Operate Networks Copyright 2013. All Rights Reserved.3 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 SDN Controller/ Network Operating System App App App App OpenFlow Packet-Forwarding Hardware OpenFlow compliant OS Packet-Forwarding Hardware OpenFlow compliant OS Packet-Forwarding Hardware OpenFlow compliant OS Well-defined Open API
  • 4. 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 Copyright 2013. All Rights Reserved.4 It replaces static, inflexible and complex networks, with networks that are agile, scalable and innovative.

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.

  • 9. So, What Are Service Providers Doing with SDN? © 2013 SDNCentral. All Rights Reserved. SDNCentral Confidential Let’s Look at Some Use Cases Being Deployed Now…
  • 10. 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) Benefits Reduced 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 10Copyright 2013. All Rights Reserved.
  • 11. 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.
  • 12. 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 12Copyright 2013. All Rights Reserved.
  • 13. 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 13Copyright 2013. All Rights Reserved.
  • 14. 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 14Copyright 2013.
