【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 inter-module interconnection structure of modular data center network and the effective organization of the routing module and the efficient communication between different module servers make how to design high bandwidth. The interconnection structure with high fault tolerance and high extensibility to support the construction of large scale and large scale data center has become the most important problem to be solved in modular data center network. In this paper, an inter-module interconnection structure, MDKautzs, is proposed to construct a large scale modular data center. This structure interconnects the module with Kautz graph through a large number of unused switches in the module, and constructs a high bandwidth without any additional high-end switching equipment. Large scale data center network with high fault tolerance and flexible and sustainable expansibility. The construction method, routing strategy and extension method of MDKautz are analyzed. The results of mathematical analysis and simulation experiments show that the new network structure has good topology characteristics and communication performance, and it can effectively support typical applications of high bandwidth and high fault tolerance in data centers.
