Abstract:
1. A method performed by a multicast cloud controller (“MCC”) in a cloud system to manage multicast traffic in a cloud network, the MCC coupled to at least one virtualized server for hosting one or more virtual machines (“VM”), wherein the virtualized server comprises at least one virtual switch (“VS”) that supports multiprotocol label switching (MPLS) and the virtual switch is coupled to a top of rack switch (“TORS”) that supports MPLS, the method comprising the steps of: receiving a leave group message at the MCC from a VM identifying a multicast group, where the VM is from a set of VMs of a tenant that are subscribed to the multicast group; deleting a flow table entry and output group at a VS of the VM, the flow table entry for forwarding outbound multicast traffic from the VM for the multicast group; deleting an action in an input group at the VS to forward incoming packets to the VM; and deleting a rule to drop loop back traffic from a TORS for the VM.
