What is SD-WAN?
A software-defined wide area network (SD-WAN) replaces conventional, static, manually configured network infrastructures. As digitalization demands ever-higher bandwidths, highest network availability and data security, as well as fast time-to-service requirements, an SD-WAN offers significant advantages for the networking of distributed enterprise sites. It uses Internet-based simple wide area networks (WANs) to rapidly provide digital services. On-site visits by qualified technicians at multiple company locations are no longer necessary.
