Evolution of SD-WAN
In 1997, the first IETF MPLS working group was
formed. MPLS technology was evolving very fast
and everyone in the industry was busy in writing
standards for Layer-3 VPN, Traffic engineering
and other areas in MPLS. Internet was growing
faster than ever and by Year-2000 MPLS became a
de-facto standard for connecting critical network
for organizations.

Amendment of SD-WAN
In 2018, right around 2 decades later, enormous
information, AI, and man-made reasoning have
become the dominant focal point and it has
presented new difficulties to network designers.
Requests on current networks are developing
quicker and huge networks are watching
exponential development rate regarding
transmission capacity because of distributed
computing, cell phones, and video utilization. A
portion of these patterns helped the advancement
of SD-WAN for example Software-Defined Wide Area
Network. According to investigators, SD-WAN
market is anticipated to grow multiple times by
2021.

Key drivers of SD-WAN

• IoT (Internet of Things) is demanding all-time
  high visibility and analytics into thousands of
  devices connected to any network.
• SD-WAN provides a central management dashboard
  to all your devices and provides a rich
  experience.
• Security is not anymore appliance-based as most
  of the applications are moving to cloud.

• SD-WAN can help you to provide consistent and
  unified security to all your network.

Key drivers of SD-WAN

• SD-WAN provides improved application performance
  and quality of service for remote and branch
  workers through intelligent path selection or
  Application Aware Routing.
• Policy creation and activation were never so easy
  in the past.
• Reduced cost in comparison to MPLS WAN links as
  SD-WAN allows you to leverage lower-priced
  broadband and LTE connections.
• SD-WAN is really helping in those scenarios as it
  comes with built-in DIA (direct internet access)
  features.

SD-WAN Architecture

SD-WAN
Architecture 
SD-WAN architecture can be divided into three
layers i.e. Infrastructure Layer, Controller
Layer, and Application Layer. This
architecture is based on standard
software-defined networking and SD-WAN is built
with similar objectives.

Business Impact of
SD-WAN

• In past, there have been many innovations which
  are cutting-edge in terms of technology but
  unfortunately, they dont add great value to the
  business. It is possible due to higher initial
  cost to use those technologies or they are far
  too complex for wider usage.
• SD-WAN is not only good in theory but it is
  making a major transformation in the industry. It
  is visible from the fact that Cisco is planning
  to bring SD-WAN to 1-million ISR routers as per
  recent blog.
