A network orchestrator capable of selecting a primary virtual internet gateway (VIG) is provided. During operation, the network orchestrator can monitor roundtrip times for multiple packets between a primary VIG and a branch gateway, and between a secondary VIG and the branch gateway. The network orchestrator can determine a first forecast roundtrip time associated with the connection between the primary VIG and branch gateway, and a second forecast roundtrip time associated with the connection between the secondary VIG and the branch gateway. The network orchestrator can then select a new primary VIG based on the first and second forecast roundtrip times.

Adaptive routing of branch traffic in software-defined wide area network (SDWAN) deployments

A network orchestrator may receive from a branch gateway (BG) an indication that the BG has joined a wide area network (WAN). The network orchestrator may assign, based in part on first load information of a first virtual internet gateway (VIG) and second load information of a second VIG, the first VIG as a primary VIG for the BG. The network orchestrator may also transmit a first redistribution cost to the first VIG. The network orchestrator may also transmit a second redistribution cost that is greater than the first redistribution cost to the second VIG.
