software-defined networks (SDNs) play an important role in reshaping the wide area network (WAN). Therefore, other WAN technologies (such as virtual WANs and hybrid WANs) are often erroneously confused with SD-WAN. While virtual and hybrid WAN technologies have similar goals to SD-WAN, there are important differences to keep in mind when choosing a solution.
SD-WAN is based on the principle of SDN, an architecture that allows centralized control of network behavior using an application programming interface (API). Applying the SDN principle to WAN technology can help connect enterprise networks by determining the best way to route traffic to and between data centers and branch offices. It also provides an affordable alternative to expensive routing hardware.
vWAN is a branch of SD-WAN. The technology is aimed at businesses that want to replace broadband connections with private WANs. The vWAN is used as a local product, including a mix of physical and virtual devices that are launched on the WAN node.
In addition to providing broadband connectivity, encryption is also used to protect vWAN traffic, which involves converting text to code to prevent unauthorized access. In addition, the technology aggregates WAN links, including broadband, allowing multiple public network links to act as one large link. The vWAN can also load balance across multiple communication channels, depending on the state of the links that make up the large link.
