> 中文摘要: 模块化数据中心网络的模块间互联结构和路由负责模块的有效组织以及不同模块服务器间的高效通信,使得如何设计具有高带宽、高容错和高可扩展能力的互联结构以支持大规模、超大规模数据中心的构建,成为模块化数据中心网络需要解决的首要问题.提出了一种构建超大规模模块化数据中心的模块间互联结构MDKautz.该结构通过模块内大量未被使用的交换机预留高速端口将模块以Kautz图互连,在无需额外增加任何高端交换设备的前提下,构造出具有高带宽、高容错和灵活可持续扩展性的超大规模数据中心网络.对MDKautz的构建方法、路由策略以及扩展方法进行了分析.数学分析和模拟实验结果证明了该新型网络结构具有良好的拓扑特性和通信性能,可有效支持数据中心高带宽、高容错的典型应用.
Abstract:The modular data center networks comprise inter-and intra-module networks. The structure and routing of inter-module networks take charge of organizing modules, and communicating among servers in different modules. Thus, it is the most important issue to design an inter-module structure with high bandwidth, high fault-tolerance, and flexible scalability to build the mega-modular data center. In this paper, an inter-module network structure called MDKautz is proposed for building the mega-modular data center. MDKautz uses Kautz as the basic interconnection topology among modules, and builds the mega-modular data center network with high bandwidth, high fault tolerance and good scalability without the need of any additional high end switches. The method for how to constructing, routing and expanding in MDKautz are analyzed. Mathematical analysis and experiment results show that MDKautz has a good topology characteristic and communication performance, and can effectively support the typical applications with high bandwidth and high fault tolerance in data center.
