Myth 1

FACT: Like most new technologies, SDN is somewhat misunderstoodand over-hyped! However, it does offer substantial benefits for dynamic virtual networks.

Myth 3

Soft ware Defi nedNetworks Don’t Need

Hardware

FACT: HAH! Software has to run on something! A common corollaryto this myth is that SDN deployments will consist of cheap minimalistplatforms in the field. This too is highly unlikely. Intelligence will still benecessary to communicate with the controller and manage the device.SDN is likely to fuel new hardware innovation.

SDN drivers and impact

Private cloud is not just about cost reduction. Agility will be a key benefit.

By 2020, 50 billion devices will be connected to wireless networks.

SDN market will grow to $2 billion by 2016… driven by the growing need for scalability and network programmability.

What are the benefits of SDN?

• Agility and Manageability• Scalability• Optimal Path Computation• Network Function Virtualization

Agility and Manageability and Scalability

Optimal Path Computation.

Cloud Computing Predictionwhy didn’t it happen?

• Virtualization will be a huge consumer of SDN but it also makes it possible. Virtual Servers present an ideal platform for Network Functions

• Standards are getting better• Open source is a strong and respected development

process• Technological advancements like programmable

Asics and the fact that many vendors have already started down these paths on their own has paved the road to SDN

YOU USED TO GET EXCITEDABOUT NETWORKING?

For the first time in years, networking is driven by new ideas and new technologies. SDN promises to end the stagnation of legacy networking.

REMEMBER WHEN

IT’S THAT TIME AGAIN

“Game Changer”

SDN Offerings can be divided into 4 segments

• Pure Approach Pure Approach 1

Overlay Approach 2

Management Approach 3

Component Approach4

PURE APPROACH

Logical “switch” devices overlay the physical

network

Logical switches define their own

topology

Underlying physical network carries data traffic for overlay

OVERLAY APPROACH

Centralized Management System

Interface to existing control planes

SDN Capabilities are achieved by centrally managing existing individual

Myth 4

It ’s Going to HappenImmediately

FACT: SDN is in its infancy. Standards are going to be debated,defined, and re-defined. Many more test beds will be necessary.It will be adopted step-by-step. “Prime time” is still a couple of years away.

When will SDN Be Widely Adopted to the Point That It Significantly Impacts the Competitive Landscape for Services?

Source: Heavy Reading

• Large distributed Data Centers- Cloud Providers, ISPs, Large enterprises.

• Network Function Virtualization as a component replacement.

• Hybrid Cloud and Disaster Resilient Designs• BYOD and Context Based Networking

Where do we expect to see SDN first?

SDN is the new network BUT SDN is in its infancy-don’t overact to the hype and don’t assume that all information is entirely accurate.

As you deal with the issues that SDN addresses make a point to check up on it over time. The environment is ripe for some very quick development cycles. After all if you are developing solutions designed to help companies react and change quickly you should be able to develop quickly

Unless you are in one of the groups we listed as the initial adopters consider approaching SDN in a functional manner. Purchasing solutions designed for SDN to solve specific needs you have today such as network functions and adopting SDN as your needs and SDN functionality match up

Recommendations

• If you are in one of those early adopter categories or you are just a progressive thing organization with some good ambitions talent. Grab an overlay solution, jump in and get your feet wet.

And keep in touch with UDI.
