Here are some of the pros and cons of each technology as we pit SD-WAN vs. MPLS in a battle of network traffic protocols.

Okay so I see no pros for MPLS, however cons seem to be, it really is overpriced and controlling.
Unlike MPLS, SD-WAN comes with no bandwidth penalties. Customers can upgrade easily by adding new links, with no changes necessary to the infrastructure or network. Perhaps the greatest selling point for SD-WAN is the ability to cost-effectively mix and match network links according to content type or priority. Both Internet broadband and 4G LTE are less expensive than MPLS, so customers can choose those links instead of the expensive MPLS network for certain types of lower-priority traffic.
