However, this Technology has its limitations, leading many organizations to search for alternative options for their WAN connections. The big advancement in Software defined networking SDN contributed in the rise of a new technology known as Software-defined WAN (SD- WAN), which enables organizations to remove the constraints of legacy networking technologies and create a flexible, reliable, and high-performance network. This project deals with the implementation of both MPLS VPN Layer 3 network and SD-WAN network architecture using Riverbed Steelconnect SD-WAN products then testing the functionality and comparing the performance of both of them and analyze if SD-WAN delivers the promised benefits.enMulti-Protocol Label Switching (MPLS)SD-WAN (Software-Defined Wide Area Networks)SD-WAN solutions: transition to next generation WANThesis
