Abstract
A multicast method, apparatus, and system for a software-defined network are presented, where the method includes creating, by a multicast sending device, a multicast group; managing, by the multicast sending device, a member of the multicast group; and completing, by a multicast routing tree management service module disposed on the multicast sending device or on a SDN controller, planning of a multicast routing tree, and converting the planning of the multicast routing tree into a flow entry modification instruction that can be executed by the SDN controller, so that the SDN controller executes the flow entry modification instruction and instructs an SDN switch using a southbound API to execute, according to a modified flow entry, a multicast task. Therefore, multicast is completed by means of mutual cooperation between the multicast sending device and the SDN network.
