Analysis about Benefits of Software-Defined Wide Area Network: A New Alternative for WAN Connectivity

Abstract

This article is based on conducting research to analyze the benefits of emerging trends in communications and networking technology, such as software-defined wide area networks. Using Waterfall as a methodology, the main objective is to carry out a technical comparison at the design and configuration level, creating a virtual environment that simulates traditional and SDWAN (Software-Defined Wide Area Network) infrastructures. The results obtained verify that the benefits of SDWAN maintain business continuity, anticipate situations in which the infrastructure can act intelligently, optimize connectivity while maintaining security, and provide improvements in the management of the entire infrastructure. People will be able to see the results obtained between both technologies and validate the benefits that SDWAN offers.

Functional segments and software defined trends in enterprise networks

“…Virtual networks also called as overlays are created over the physical network to improve the network utilization and quickly create connections between end points. The network controller, which is programmed in such a way that it has a complete view of the network architecture, oversees continuously assessing the status of the links and dynamically determining which route should be used to send the data [37]. The challenge in traditional WAN was that it was not aware of the application and could not prioritize packet transfer through links at real time.…”
