[SD-WAN vs MPLS vs SDN] | Pros and Cons

MPLS is a technique, not a service. It was started at the turn of the century, and it works to address determine efficient routes for packets that enter a network. Using MPLS, a packet will go into the network and be assigned to a specific FEC. It's a layer 2.5 service, and it's not as modern as SD-WAN.
