Comparison
Traditional WAN vs Software-Defined WAN (SD-WAN)
An SD-WAN can connect several branch locations to a central hub office. Because it is abstracted from hardware, it is more flexible and available than a standard WAN.
Traditional WAN
The traditional WAN (wide-area network) function was to connect users at the branch or campus to applications hosted on servers in the data center. Typically, dedicated MPLS circuits were used to help ensure security and reliable connectivity. This doesn't work in a cloud-centric world.
vs
SD-WAN
A software-defined wide area network (SD-WAN) is a wide area network that uses software-defined network technology, such as communicating over the Internet using overlay tunnels which are encrypted when destined for internal organization locations.
Product Advantage
Benefit of Software-Defined WAN (SD-WAN)
An SD-WAN can connect several branch locations to a central hub office. Because it is abstracted from hardware, it is more flexible and available than a standard WAN.
Improve Performance
SD-WAN prioritizes critical traffic, optimizing cloud app performance.
Reduce Cost
cuts costs by using local internet, direct cloud access, and reducing WAN traffic.
Boost Security
SD-WAN network protection offers built-in security: NGFW, IPS, encryption, AV, sandboxing.
Increase Operational Agility
SD-WAN prioritizes critical traffic, optimizing cloud app performance.
Simplifying IT Infrastructure
simplifies WAN infrastructure, offloads non-critical apps, and automates monitoring.
Improve User Experience
Improves user experience by dynamically routing traffic based on network conditions.
SD-WAN and MPLS Differentiation

Performance & Availablity
SD-WAN
Simplifying WAN infrastructure, , using broadband to off-load non-critical business apps, automating monitoring tasks, and managing traffic through a centralized controller.
MPLS
Broad application visibility
Consolidated services greatly reduce TCO
Enables MPLS, broadand, LTE for high-speed
Internet traffic backhauled to the data center
Packet routing limits visibility
Expensive to build and maintain
MPLS offers limited bandwidth and single point of failure

Maintenance
Offer scalability and flexibility
- Require more maintenance and work
- Require more level of expertise
- Difficult for additional site maintenance
Performance & Bandwidth
Offer dynamic path selection, Quality of Service and application aware routing
Generally, experience considerable latency due to distance between sites and spikes in congestions that affect performance
Reliability
Offer secured system, failover security feature, Automatically fix a service failure or outage
- Offer secured system
- DOES NOT offer failover security feature
- DOES NOT automatically fix a service failure
Overall Benefit
- More seamless user experience by minimize packet loss
- Support for employees work from anywhere
- Offer Network connection flexibility
Support for Dedicated Internet Access
