In the context of Cisco SD-WAN, what does the acronym REST stand for?

In the context of Cisco SD-WAN, REST stands for Representational State Transfer. This architectural style is used in the design of networked applications and is particularly integral to the way web services communicate over the HTTP protocol.

REST is based on a set of principles that include stateless communication and the use of standard HTTP methods such as GET, POST, PUT, and DELETE. It allows different components of applications to interact in a way that fosters the growth of a robust, scalable, and easily consumable API. Many applications, including those in Cisco's SD-WAN solutions, utilize REST APIs to enable configuration, monitoring, and management of network devices and services in a straightforward manner.

This architecture enables systems to be loosely coupled, simplifying the integration of diverse components and enabling easier maintenance and updates. In Cisco SD-WAN, the use of RESTful APIs facilitates efficient communication between the control plane and the data plane, allowing for better performance and flexibility across the wide area network.
