8. First, Why SDN?
Networks are an order of magnitude larger; automation has lagged
SDN solves inflexibilities and inefficiencies that inhibit scale & automation

9. What is SDN and What are Its Benefits?
SDN Definition
SDN Benefits
Centralization of control of the
network via the
Efficiency: optimize existing
applications, services, and
infrastructure
Separation of control logic to offdevice compute, that
Scale: rapidly grow existing
applications and services
Enables automation and
orchestration of network services via
Open programmatic interfaces
Innovation: create and deliver new

27. SDN Perspectives in 2013
Our learnings from client engagements & operating SDNCentral
Open Source
• Limited developer communities / concentrated at few companies
• Usually controlled by single commercial entity. Potentially risky
• Lack of reference implementation slowing down OpenFlow
Established
Vendors
• Scrambling to claim everything new is ‘SDN’
• Spotty and inconsistent support for SDN
• Not one vendor / product fits all customers or specific problems.
Start Ups
Customers
• Attempt to sell packaged products at a stage where value is created by custom
solutions
• Few or no production customers
• Early adopters looking to reap competitive advantage via SDN
• Financials, Web 2.0, Service Providers
• Most revenue is professional services driven

28. Pitfalls to Avoid
Mistakes we see clients making and have provided advice on
Attempting to Run before
Crawling
Believing people who say
they know how to solve
your problem
Lack of clear business objective /
problem statement
Usually set up to sell products
Failure to manage expectations
Product designed 2–3 years back
before problems and use cases were
well understood
Failure to understand limitations of
current software & hardware
Forces you on a path with solution
that was never designed for your use
case in mind

29. So, What to Do in 2013?
Learn and read-up on SDN
Establish a valid business use-case where SDN can bring value
Work with trusted vendors and advisors to design a POC
Use learnings to determine appropriate next steps in late 2013, early 2014,
when vendor products mature

30. Questions to Ask Prospective SDN Vendors
How to separate SDN reality from SDN and vendor hype in an early market.
•
•
•
How many current trials do you
have running??
Who are your typical customers?
Are you SP or Enterprise focused?
•
How what use-cases / solutions do
you support? Which one are you
focused on?
•
•
•
•
How many production / paid
deployments?
Do you provide products or
services?
How much money have you raised
& when?
Where does <insert your company
name > sit on your priority list?
