Data Center Multicast with High Stability

Multicast benefits data center group communication in both saving network traffic and improving application throughput. The SLA (Service Level Agreement) of cloud service requires the computation correctness of distributed applications, translating to the requirement of reliable Multicast delivery. In this paper we present INICE, a high stable Multicast approach for data center network. The key idea of INICE is to minimize the impact of end host instability on the Multicast performance, by computing the link weight with node stability. A Multicast tree-aware backup overlay is purposely built on hierarchical clustering of stable nodes. INICE proposes feasible and highly efficient node clustering algorithm, and guarantees the out-degree of node being a constant. The backup overlay multicast tree is organized in such a way that it causes little multicast tree rebuilding. We extensively evaluate the INICE algorithm by theoretical analysis and experiments.
