摘要
在新的应用模式下,传统层次结构数据中心网络在规模、带宽、扩展性和成本方面存在诸多不足.为了适应新型应用的需求,数据中心网络需要在低成本的前提下,满足高扩展性、低配置开销、健壮性和节能的要求.首先,概述了传统数据中心网络体系结构及其不足,并指出了新的需求;其次,将现有方案划分为两类,即以网络为中心和以服务器为中心的方案;然后,对两类方案中的代表性结构进行了详细的综述和对比分析;最后指出了数据中心网络未来的发展方向.
Under the new application mode, the traditional hierarchy data centers face several limitations in size, bandwidth, scalability, and cost. In order to meet the needs of new applications, data center network should fulfill the requirements with low-cost, such as high scalability, low configuration overhead, robustness and energy-saving. First, the shortcomings of the traditional data center network architecture are summarized, and new requirements are pointed out. Secondly, the existing proposals are divided into two categories, i.e. server-centric and network-centric. Then, several representative architectures of these two categories are overviewed and compared in detail. Finally, the future directions of data center network are discussed.
