SD-WAN stands for Software-Defined Wide Area Networking. It is an approach to network connectivity that uses software to centrally manage and control network traffic across a wide area network (WAN). The goal of SD-WAN is to simplify the management and operation of a WAN by separating the networking hardware from its control mechanism, which is typically accomplished through software-defined networking (SDN).

SD-WAN technology provides several benefits, including the ability to route traffic over multiple paths, enabling network administrators to choose the best path for each type of traffic based on factors such as network availability, latency, and packet loss. This can result in better performance, higher bandwidth utilization, and improved reliability.

In addition, SD-WAN can help organizations reduce their WAN costs by leveraging multiple types of connections, such as broadband and cellular, instead of relying solely on expensive dedicated lines. It can also improve network security by implementing policy-based routing and encryption, as well as providing better visibility and control over network traffic.

Overall, SD-WAN has become an increasingly popular technology for organizations looking to modernize their WAN infrastructure and simplify network management
