摘要 数据中心网络的性能在很大程度上决定云计算的性能,但随着应用需求的不断提高,数据中心网络中的服务器数量变得越来越庞大。如何将大量服务器连接起来,从而构建一个性能良好的数据中心网络,是提升云计算性能所面临的一个挑战。传统的树型数据中心网络存在带宽瓶颈和单点失效等问题,目前提出的DCell、BCube和FiConn等数据中心网络具有较大的带宽和容错性,但DCell和FiConn在交换机失效时服务器间的容错路径长度较大;而BCube在规模较大时对交换机性能有较高要求。综合上述考虑,基于具有优良性能的交叉立方体,我们提出了一种新的以服务器为中心的数据中心网络,称为BCDC。进一步,我们研究了BCDC网络的顶点度数,通信算法以及容错路由算法。另外,我们分析了BCDC上路由算法的性能及时间复杂度并进行相应的模拟实验。该研究将为新型数据中心网络的设计和实现提供重要依据。

Abstract: The capability of the data center network largely decides the performance of cloud computing. However, the number of servers in the data center network becomes increasingly huge, because of the continuous growth of the application requirements. The performance improvement of cloud computing faces great challenges of how to connect a large number of servers in building a data center network with promising performance. Traditional tree-based data center networks have issues of bandwidth bottleneck, failure of single switch, etc. Recently proposed data center networks such as DCell, FiConn, and BCube, have larger bandwidth and better fault-tolerance with respect to traditional tree-based data center networks. Nonetheless, for DCell and FiConn, the fault-tolerant length of path between servers increases in case of failure of switches; BCube requires higher performance in switches when its scale is enlarged. Based on the above considerations, we propose a new server-centric data center network, called BCDC, based on crossed cube with excellent performance. Then, we study the connectivity of BCDC networks. Furthermore, we propose communication algorithms and fault-tolerant routing algorithm of BCDC networks. Moreover, we analyze the performance and time complexities of the proposed algorithms in BCDC networks. Our research will provide the basis for design and implementation of a new family of data center networks.
