There are very few technologies out there that have the
potential to change the way we work and make indelible impacts on businesses in
significant ways. SD-WAN or Software Defined Networking is one of them. This
technology is basically the entire intelligence behind routing and switching.
In addition data movements and digital voice traffic is confined within the
software but removed from hardware that is responsible for controlling network
What does Software Defined Network have to do with it?
This might seem like a very small
change; all you have to do is move the entire routing and switching system from
its original position. In other words, you are altering the intelligence as
such, just relocating it. However, this small difference has massive
consequences; it allows you to virtualize the functions of the network
intelligence which in turn allows you to achieve a number of things. For one
thing, you can swap intelligent routers and switches across your network with
simpler ones that are easier to operate and without the need of other functions
that are present in the devices.
Doing this can simplify
configuration which basically means that it will allow you to use cost
effective devices. One other advantage of software defined networking is that
it can also provide a centralized location for:
tables and intelligence
network intelligence from hardware to software
Besides ease of access, the switching
networks this way allows more flexibility as well as consolidation. All
alterations are applied in a single central location but perhaps the best
benefit of this is the way it supports virtual environments and businesses.
With cloud based technology, private and public, enterprises could transform
the way they operate by creating flexible solutions to meet their requirements and
can even add, remove and adjust new elements in their infrastructure without
disruption and according to demand.
Software defined networking
allowed network and virtual environments to integrate with each other which was
not possible before. Doing this allows the network to adjust according to
demands as and when they crop up.
However, the software benefits
more than just the environment it is in. It also has significant value when it
comes to networking in wider networking. SD-WAN provides businesses more
configuration options for not only the devices utilized in their network, but
the entire network itself. In other words, using SD-WAN businesses can use different
networks that they did not have access to before. For instance, in a
traditional network, users could forward traffic over a number of different
networks. In short, they can send important traffic over a MPLS network and
less important traffic over a wireless one which is comparatively inexpensive.
Some technologies based on SD-WAN
can take this on a whole different level via algorithmic nodes which can be
integrated as an application type function. If these can be integrated into
software, the benefits will literally be endless.
Besides small businesses, SD-WAN
setups are also highly beneficial for medium sized businesses which more often
than not lack the in-house IT networking that could manage their infrastructure.
