论文摘要
如今，数据中心（DC）拥有数以万计的服务器和开关，并通过高速通信链接互连。随着云DC的迅速增长，在大小和数量上，已经采取了巨大的努力来有效地设计网络并管理这些DC内的流量。但是，几乎没有努力衡量，理解和融合这些DC的网络级流量的行为。在本文中，我们旨在对这些DC研究提出系统的分类学和调查。具体而言，我们的调查首先将直流网络流量行为分解为两个主要阶段，即（1）数据收集方法和（2）研究结果，然后对每个阶段的最新研究进行了分类和讨论。最后，该调查强调了与DC网络流量有关的研究挑战，需要进一步的研究调查。
Data centers (DCs) nowadays house tens of thousands of servers and switches, interconnected by high-speed communication links. With the rapid growth of cloud DCs, in both size and number, tremendous efforts have been undertaken to efficiently design the network and manage the traffic within these DCs. However, little effort has been made toward measuring, understanding and chattelizing how the network-level traffic of these DCs behave. In this paper, we aim to present a systematic taxonomy and survey of these DC studies. Specifically, our survey first decomposes DC network traffic behavior into two main stages, namely (1) data collection methodologies and (2) research findings, and then classifies and discusses the recent research studies in each stage. Finally, the survey highlights few research challenges related to DC network traffic that require further research investigation.
