Multicast is an important communication way, which addresses how to distribute the data from one or many sources to a group of destination computers simultaneously. Recently emerging software-defined networking (SDN) separates the network control plane from the data forwarding plane with the promise to dramatically improve network resource utilization. The multicast in this new network paradigm should be reconsidered according to the new network features. In this paper, we introduce the
