Abstract: Abstract Efficient multicast support is very important in data center (DC) networks, as many big data systems in data centers are bandwidth-hungry. Multicast implementations in DC networks are usually overlay-based. The major challenges are how can we accurately infer the topology of DC networks with both wired and wireless millimeter wavelength (MMW) links and how to design multicast algorithm for these topologies. In this paper, we first use hierarchical clustering to accurately infer the topology. Then, we propose the Inter-Rack First Multicast (IRFM) algorithm to match the fan-in nature of DC topologies. Evaluation results demonstrate that IRFM is $$3.7{-}11.2{\times }$$3.7-11.2× faster than naive multicast implementations in the pure wired case, and $$4.8{-}14.6{\times }$$4.8-14.6× faster in the case of MMW enhancement.
