Will SD-WAN replace MPLS?

• SDWAN -Software Define Wide Area Network.
• MPLS  - Multi-Protocol  Label Switching.

As you know that there are a lot of digital transformations happening in recent years and the things have been changing with rapid pace.Starting from the desktop websites to mobile websites and then from mobile apps to cloud apps, OTT media services.But the problem was with the network, its was designed on the basis of hops,device,source and destination based with no visibility to applications.The network was not application centric.

 

In order to meet the current business requirement enterprise network need to be more intelligent,cost-effective and with fast WAN deployments.That's why SDWAN solution came into picture to fill-up this gap.

Let's take an example, In picture shown below you can see a car dashboard. It was late 80's or 90's design which had basic information to reach from Point A to B.You can relate this to MPLS without SDWAN. MPLS will still be there for backbone connectivity.But this design will not meet today's business requirement.
