Abstract: The present technology discloses methods, systems, and non-transitory computer-readable media for defining, for a network primitive in a network domain, whether the network primitive can receive data carrying an assigned context associated from one or more source nodes through a software-defined wide area network (SDWAN) fabric overlay; advertising a capability of the network primitive, the capability stating whether the network primitive can receive the data carrying the assigned context; and controlling selective transmission of the data carrying the assigned context from the one or more source nodes to the network primitive through the SDWAN fabric overlay based on the capability of the network primitive to receive the data carrying the assigned context.

Abstract: The present disclosure is directed to a centralized control policy for multicast replicator selection. Methods include receiving multicast advertisements from a plurality of edge devices configured with multicast protocol, each multicast advertisement including information indicating whether an associated edge device is a replicator; analyzing multicast advertisements from the plurality of edge devices to identify one or more replicators; receiving a centralized policy configuration associated with at least one control policy that includes a preference related to selection of at least one replicator from the identified one or more replicators, the preference applicable to a defined set of edge devices from the plurality of edge devices; and updating at least one multicast advertisement with the control policy for transmission to the defined set of edge devices, the updated at least one multicast advertisement indicating the preference for replicator selection for the defined set of edge devices based on the control policy.
