SD-WAN applies SDN technology to WAN connections, including MPLS. It offers many advantages over MPLS. It increases visibility, performance, scalability, and control by removing geographic boundaries. It offers a higher level of security and no bandwidth penalties.
However, while MPLS costs more and not as modern as SD-WAN, it provides efficient delivery of packets. It is a layer 2.5 service and has the ability to maintain the quality of real-time protocols.
SDN focuses internally within the LAN but offers some advantages over MPLS. The advantages of SDN include providing a clear and broad view of the entire network. It can also include changes that will increase the efficiency and speed of the network. Furthermore, the clear visibility of the entire network protects it from security breaches.
