What role does the vEdge play in the SD-WAN architecture?

In the context of an SD-WAN architecture, the vEdge devices primarily serve within the Data Plane. The Data Plane is responsible for the actual forwarding of data packets across the network, handling the transmission of user data between branch locations and the data center or cloud environments. vEdge routers, as part of this plane, facilitate the efficient routing and switching of traffic based on policies established by the network administrator.

These devices utilize various techniques to optimize data transmission, including path selection, traffic engineering, and real-time monitoring of WAN performance metrics. By processing user data traffic and applying the policies defined in the Control Plane, vEdge routers ensure that traffic flows efficiently, improving user experience and the overall performance of applications.

In contrast, other components in SD-WAN architecture serve different purposes: the Orchestration Plane is responsible for the deployment and management of the network; the Control Plane facilitates policy distribution and monitoring; and the Management Plane focuses on system management functions such as configuration and logging. Understanding these roles clarifies why the vEdge's position in the Data Plane is pivotal for effective SD-WAN operation.
