数据中心中的组播通信因其对社交网络服务和文件分发的需求而受到极大关注，例如面向虚拟机的操作系统更新。多播通信提供了高效的网络资源使用的优点。据作者所知，只有可行性和可扩展性的问题已被处理在已发表的论文在数据中心的多播通信。数据中心网络通常以高利用率运行，因此拥塞控制是最重要的技术问题之一。这也是组播通信的情况下，但还没有发表任何论文有关组播拥塞控制在数据中心。本文提出了一种新的多播拥塞控制算法DCMC（Data Center Multicast Congestion Control）。DCMC是一种端到端的组播拥塞控制，它根据拥塞最严重的接收方的估计吞吐量来调整发送速率。通过基于方程的接收机吞吐量估计来选择最严重拥塞的接收机。我们的仿真结果表明，DCMC可以实现TCP友好，即公平性，与DCTCP保持高链路利用率。
Multicast communications in data center has gotten great attention with its requirement for social networking services and file distribution, such as OS update towards virtual machines. Multicast communications offer advantage of efficient network resource usage. To the best of authors' knowledge, only feasibility and scalability issues have been treated in published papers for multicast communications in data centers. Data center networks generally operate at high utilization, so congestion control is one of the most important technical issues. This is also the case for multicast communications, but there have not been published any papers related to multicast congestion control in data centers. In this paper, we propose a new multicast congestion control, DCMC (Data Center Multicast Congestion control). DCMC is an end-to-end multicast congestion control and adjusts the sending rate to the estimated throughput of the worst congested receiver. The worst congested receiver is selected by equation-based estimation of receiver's throughput. Our simulation results show that DCMC can achieve TCP friendliness, i.e. fairness, with DCTCP with keeping high link utilization.
