A Survey of Multicast in Software-Defined Networking
Weidong Gu, Xinchang Zhang, Bin Gong, Lu Wang · Advances in engineering research/Advances in Engineering Research · 2015
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 multicast technique in SDN, including SDN-based Multicast in Datacenter, Multicast Routing in SDN and Multicast Tree Packing in SDN.We believe that the multicast technique in SDN, especially the multicast tree packing, has better potential performance than that in traditional network.
