"Software-defined Wide Area Network (SD-WAN) is a modern WAN solution that simplifies network management and provides integration with the cloud. SD-WAN is an application of Software-defined networking. SD-WAN has grown with SDN in recent years and adoption of SD-WAN started when its implementation showed tangible results. SD-WAN adoption has grown in the enterprises and they are reaping the benefits of using SD-WAN over the Traditional WAN technologies. Let's have a look at how an SD-WAN implementation in a business can be beneficial. To determine that we will be using an example of an organization, we will try to understand why it is beneficial and in some cases critical to adopt the new technology rather than investing in the existing MPLS infrastructure. By transferring these functions to software and a central controller, SD-WAN virtualizes networking services and reduces the complexity of configuring and managing enterprise networks. This new solution can also serve as a replacement for MPLS, which has been in use since the 1990s. As a result, there is a need to analyze these SD-WAN solutions, which is the objective of this Capstone project. This project will look at one of the most prevalent networking technology in today’s networking world, i.e., Software-Defined Wide-Area Network (SD-WAN). Various vendors have designed and improved their SD-WAN solutions in recent years. The analysis will be based on a review of white papers, vendor documentation and research papers. The goal is to provide a thorough analysis of these SD-WAN Solutions offered by these vendors and to discuss SASE which could be the new best thing to revolutionize enterprise networks."
