摘要： 在分析现有数据中心网络结构的基础上，提出一种容错的数据中心网络结构DCUBE。采用模块化方式定义增强扩展性，通过对服务器结点的失效处理提高容错性，利用服务器之间的并行路径，提高结点之间的带宽吞吐量。实验结果表明，DCUBE能较好地满足数据中心对网络结构的要求，而且可提供更高的带宽吞吐量。

Abstract: This paper proposes a fault-tolerant data center network structure——DCUBE. It uses modular definition way to enhance extensibility. It makes the server nodes failure treatment to improve fault tolerance, and adopts the parallel path between to improve the bandwidth throughput between the nodes. Experimental results show that DCUBE can better satisfy the network architecture requirements of data center, fault-tolerant, and it can provide high throughput.

Key words: cloud computing, data center network, modular, fault-tolerant extensibility, bandwidth throughput
