Software-defined Wide Area Network (SD-WAN)

An SD-WAN is a software-based wide-area network (software-defined wide area network) and thus a virtual WAN network. Companies are extremely flexible with the SD-WAN because they can securely connect users with different applications via LTE and other broadband services. The SD-WAN controls the data traffic within the WAN centrally and securely. The key benefits of an SD-WAN are that it reduces costs through independent data transmission, provides high flexibility between users and applications, is user-friendly with respect to various cloud applications, and greatly simplifies cloud-based management. SD-WANs fully support applications from local data centers, cloud services or SaaS services such as Dropbox or Office 365, and also ensure high performance of the applications.
