Software-defined wide-area networks (SD-WAN) is an approach to
network
connectivity that improves
application
performance, accelerates productivity and simplifies
network management. SD-WAN uses virtualization technology to apply the benefits of
software-defined networking
to traditional
router-centric,
hardware-based networks to more intelligently direct traffic across a
wide-area network (WAN).

Traditional WAN vs. SD-WAN

The purpose of a traditional WAN is to connect users in branch offices to applications
hosted
in
on-premises
data centers
anytime, anywhere and from any
device. This was achieved by directing
traffic
across routers, usually using a
Multiprotocol Tera Switching (MPLS)
connection. Traffic was directed based on
IP addresses
and
access control lists, with
control
functions distributed across all network routers.

Most apps are now hosted in the cloud due to the adoption of
software-as-a-service (SaaS)
and
infrastructure-as-a-service (Iaa
S
). Traditional WAN architectures can’t efficiently handle this influx of cloud traffic.

This created a need to find new methods for directing traffic, as sending cloud traffic to an on-premises data center before being sent to the internet results in
latency, degraded application performance, costly
bandwidth
and
security vulnerabilities. SD-WAN is application-aware, so it directs traffic across the network based on business requirements for applications, such as priority, performance and
security policies.

SD-WAN is able to host applications on all
platforms, including on-premises data centers, branch offices and
public
or
private clouds. It can also leverage any combination of transport services, including MPLS,
broadband internet
and
4G/5G
LTE.

Improved performance and productivity

More efficient traffic directing means improved application performance.
High availability
with predictable service means teams are able to be more agile with their
workflows. This leads to a better user experience, and ultimately, improved productivity.

Centralized management

SD-WAN decouples the networking hardware, or the data forwarding plane, from the control function to simplify management and operations. A single, centralized dashboard makes it easy to configure and manage the WAN. Policies that govern how applications are delivered to users are defined centrally and assigned automatically across potentially thousands of SD-WAN appliances connected to a network. Admins can also pull reports on application and WAN performance.
