ABSTRACT
The Software-defined wide-area network (SD-WAN) controller must be able to quickly interconnect with operations and business support systems (OSS/BSS) and third-party application systems like the public Clouds. For enterprise end users, the adoption of SD-WAN is also a value evolving process. Whereas SD-WAN was initially thought of an overlay that abstracts the transport network and provides direct and cost-effective links to the Cloud for branches, it is evolving to be more about a robust digital platform for application-driven policy routing, analytics, and enhanced security. Some industry standard and protocols that allow multivendor SD-WAN integration and interoperability are still due. A comprehensive Industry survey found significant difference between pre and post SD-WAN adoption for enterprises. Their teams need to build up expertise in jobs including access links aggregation, SD-WAN solution deployment and management, and multiple Wide-area network services and partners management on the network.
