数据中心网络的研究进展与趋势

Data Center Network Research Progress and Trends

作为云计算的基础设施和下一代网络技术的创新平台,数据中心网络的研究成为了近年来学术界和工业界关注的热点.文中围绕数据中心网络研究的基本问题,介绍了国际国内的研究现状,包括数据中心网络拓扑设计、传输协议、无线通信、增强以太网、虚拟化、节能机制和软件定义网络(Software Defined Networking,SDN)等,并展望了数据中心网络的发展趋势.

As the key infrastructure of cloud computing and innovation platform for next-genera- tion networking, recently data center network has been a hot research topic in both academia and industry. Based on the fundamental research problems in data center network, we first describe the international and domestic research progress of this area in this paper, including data center network topology design, transport protocol, wireless communication, enhanced Ethernet, virtu- alization, energy saving, SDN （software defined networking）, etc., and then prospect the research trend.
