随着现代数据中心网络（DCN）的快速部署，已经观察到关于DCN架构、拥塞通知、TCP Incast和功耗的许多问题。在本文中，我们提供了一个全面的调查，在DCN的最新研究活动，重点是网络架构设计，拥塞通知算法，TCP Incast和功耗。我们详细描述了一个典型的现代DCN的体系结构。此外，我们调查的挑战，典型的基于树的分层DCN架构今天遇到的最佳DCN架构的要求，我们提出的DCN架构分为交换机为中心的拓扑结构和服务器为中心的拓扑结构。一节还专门描述一些新提出的DCN架构。我们提出了一个简短的概述TCP Incast问题沿着与以前提出的解决方案。我们还回顾了最近的节能解决方案，以最大限度地减少DCN的功耗。最后，我们概述了未来可能的研究课题在DCN。
With rapid deployment of modern data center networks (DCNs), many problems with respect to DCN architecture, congestion notification, TCP Incast, and power consumption have been observed. In this paper, we provide a comprehensive survey of the most recent research activities in DCNs, with emphasis on the network architecture design, congestion notification algorithms, TCP Incast, and power consumption. We describe in detail the architecture of a typical modern DCN. Furthermore, we investigate the challenges of the typical tree-based hierarchical DCN architecture encountered today and the requirements for the optimal DCN architecture, and we classify the proposed DCN architectures into switch-centric topology and server-centric topology. A section is also devoted to describe some newly proposed DCN architectures. We present a brief overview of the TCP Incast problem along with previously proposed solutions. We also review the recent energy-efficient solutions to minimize the power consumption in DCNs. Finally, we outline possible future research topics in DCNs.
