Abstract: Systems and methods are provided for reducing WAN bandwidth consumption used by multicast for large scale software-defined branch deployments. In particular, a cloud-based multicast orchestrator may be implemented as part of an SD-WAN service. This cloud-based multicast orchestrator may orchestrate routes for multicast traffic between a multicast source and the various branches of the large scale software-defined branch deployment. This cloud-based multicast orchestrator may orchestrate routes for multicast traffic which reduce/optimize WAN bandwidth consumption. In combination with the cloud-based multicast orchestrator, examples may utilize a branch gateway hierarchy which designates one branch gateway a “leader” for a given multicast stream to further reduce WAN bandwidth consumption used by multicast.

Abstract: Examples described herein relate to a centralized overlay multicast orchestrator in a software-defined wide area network (SD-WAN). The overlay multicast orchestrator receives and maintains state information from multicast agents deployed on overlay network nodes. Based on the state information, the overlay multicast orchestrator identifies a first set of overlay network nodes connected to a source and a second set of overlay network nodes connected to hosts requesting a multicast stream. The overlay multicast orchestrator computes and distributes a multicast tree representing a path for transmission of the multicast stream to the requesting hosts.
