While it’s true that Software Defined Networks (SDNs) continue to grow and
get the majority of the buzz in the news these days, another technology
called Application Defined Networks (ADNs) is starting to make its presence
known in the business world as well and it has the potential to really take
off. Based on what I know about Application Defined Networks (ADNs) this
technology has the ability to fill some of the gaps that Software Defined
Networks (SDNs) present.
Application Defined Networks (ADNs) and Software Defined Networks (SDNs)
are both based on similar concepts but solve separate ends of a complex
problem. Application Defined Networks (ADNs) allow enterprises to securely
reach and consume economic benefits of cloud services, where Software
Defined Networks (SDNs) are resident. Software Defined Networks (SDNs)
primary focus is inside the data center to allow for greater dynamic
allocation of network resources to deal with spikes in resource demands.
Software Defined Networks (SDNs) have not addressed the complex task of
facilitating secure access to the cloud data centers faced by multi-site
enterprises. Application Defined Networks (ADNs) primary focus is
virtualizing the edge of the data center creating secure access to the
cloud services. Application Defined Networks (ADNs) focus on the millions
of brick and mortar enterprise locations need to resolve the core security,
performance, and reliability conflicts that are limiting application
expansion to data centers.
For the purposes of my comment, an application can basically be defined by
a business need and may include things like payment, loyalty, guest access
Wi-Fi, point-of-sale support, tank monitoring, etc.
In short, an Application Defined Network (ADN) simplifies security by
establishing discrete independent networks that do not require complex
security rules to partition traffic types. It is designed so that specific
security and performance policies can be established at the application
level versus the network interface level which allows for applications with
contrasting security policy requirements to be completely isolated from one
another and facilitated with customized security features. It eliminates
the need for new application specific devices to securely petition discrete
application networks and eliminates future capital costs. If an Application
Defined Network (ADN) is breached by an outside party, the ability of the
breach to bleed between applications is virtually eliminated due to each
application having customized security and performance policies.
After comparing both of these technologies, I feel that Application Defined
Networks (ADNs) have an advantage over Software Defined Networks (SDNs)
simply because Software Defined Networks (SDNs) have not addressed the
complex task of facilitating secure access to the cloud or data centers for
multi-site enterprises. Most businesses today have multiple locations over
a large geographic area and this is exactly what Application Defined
Networks (ADNs) are designed to handle.
Thank you for basic introduction about SDN… Very good………
Eli any opinions on Alcatel/Lucents SDN offering? Thanks
An exceptional way of explaining things… that’s for sure.
Thank you eli
You explain things so well. You need a TV show.
Great :))
Awesome way of explaining.. You are blessed with Teaching skills.. Thanks.
great video Eli
Awesome video on SDNs. Now I’m pretty clear what SDN is.. Thanks Eli..
thank you Eli.. you gave very clear view of SDN’s, i want to see myself as
a programmer to that control plane, but i am really confused, can you
please tell me how to start
SDN tech
Thanks for the explanation
this seems to me to be similar to Cisco software on things like catalyst
6500 series etc where the supervisor is separated and the network is
tightly controlled for the network and the Unified Network architecture is
this similar or a simpler version for SOHO /SB use? especially some of the
newer stuff i have seen in there VOIP stuff (doing same sort of stuff as
your angry wife example) thanks for the video
Great explanation Eli, thank you. For a person working at one of those
networking companies you mentioned, your method of explaining SDN provides
great clarity on what it is and is not.
