Dynamic establishment of application-specific network tunnels between network devices by an SDWAN controller

Abstract:

Systems and methods for dynamically establishing network overlay tunnels between edges within different groups of a network architecture are provided. According to an embodiment, a Software-Defined Wide Area Network (SDWAN) controller associated with a private network, receives a request to initiate a dynamic Virtual Private Network (VPN) link for a network session between a source edge and a destination edge. The SDWAN controller determines configuration information for each of the source edge and the destination edge, which includes VPN and SDWAN configuration information determined based on pre-configured rules managed by the SDWAN controller for generating the dynamic VPN link between the source edge and the destination edge. The SDWAN controller directs the source edge and the destination edge to set up a VPN overlay tunnel in accordance with the determined configuration information by pushing the determined configuration information to each of the source edge and the destination edge.
