Abstract: Embodiments herein disclose path selection for data traffic within a software-defined wide area network using traffic metrics. Some embodiments relate to a method that includes polling peers of the SD-WAN for traffic metrics, receiving traffic metrics from at least a portion of the peers, combining the received traffic metrics, calculating performance of a plurality of possible paths from a source node to a destination node, the nodes being within the SD-WAN topology, and selecting a path from the source node to the destination node based on the calculated performance.

Abstract: One embodiment of the present invention provides a switch. The switch includes a processor, a storage device, a multicast management module, and a graceful recovery module. The multicast management module participates in a multicast tree of a multicast group. The graceful recovery module determines a recovery event and constructs a message indicating the recovery event for a second switch. The switch and the second switch belong to a first virtual local area network (VLAN). The graceful recovery module then identifies a completion notification message from the second switch indicating a completion of replaying multicast information stored in the second switch and includes multicast information received from the second switch in a local multicast database.
