Multicast method, device, equipment and computer storage medium

The embodiment of the invention relates to the technical field of communication, and discloses a multicast method, which comprises the following steps of: determining virtual machine information of a target virtual machine; the virtual machine information is converted into virtual port information corresponding to a preset SDN controller; sending the virtual port information to the SDN controller, so that the SDN controller adds the target virtual machine into a multicast group of a virtual multicast network corresponding to the target cloud platform; the virtual multicast network is pre-constructed by the SDN controller according to network configuration information; the network configuration information is obtained by converting logic network information of a target cloud platform; the target cloud platform comprises the target virtual machine. According to the embodiment of the invention, the processing efficiency of the multicast service in the cloud environment is improved. 本发明实施例涉及通信技术领域，公开了一种组播方法，该方法包括
