  • Cloud-end data multicast method and system, and computer device
    Patent number: 10958723
    Abstract: A cloud-end data multicast method includes: obtaining a multicast packet, the multicast packet carrying a tenant identifier, a destination address, and a source address; and searching for a multicast group according to the tenant identifier and the destination address. The multicast group includes multicast members. The method also includes obtaining routes corresponding to the multicast members; generating a routing tree according to the routes corresponding to multicast members; and obtaining member addresses corresponding to the multicast members. The method also includes obtaining an address list containing addresses of target members that are identified to receive the multicast packet by performing address filtering according to the source address and the member addresses; encapsulating the multicast packet; and delivering the encapsulated multicast packet to the target members according to the address list and the routing tree.
