在过去的十年中，由于数据量和类型的爆炸性增长，世界各地建造了许多数据中心。成本和能耗已成为构建这些数据中心的最重要挑战。今天的数据中心使用商品计算机和交换机，而不是高端服务器和互连来提高成本效益。在本文中，我们提出了一种新的互连网络称为<italic>交换立方连通圈（ExCCC）</italic>。<italic>ExCCC</italic>网络是<italic>交换超立方体（EH）</italic>网络的扩展，通过将每个节点替换为循环。<italic>EH</italic>网络基于从<italic>超立方体</italic>网络中删除链接，这使得<italic>EH</italic>网络在扩展时更具成本效益。在分析<italic>了ExCCC</italic>的拓扑特性后，利用<italic>ExCCC</italic>架构的优势，采用商用交换机构建了一类新的数据中心网络模型<italic>ExCCC-DCN</italic>。分析和实验结果表明，所提出的<italic>ExCCC-DCN</italic>模型在总成本、功耗、可扩展性和其他静态特性方面明显优于四种最先进的数据中心网络模型。它同时实现了低成本、低能耗、高网络吞吐量和高可扩展性的目标。
Over the past decade, many data centers have been constructed around the world due to the explosive growth of data volume and type. The cost and energy consumption have become the most important challenges of building those data centers. Data centers today use commodity computers and switches instead of high-end servers and interconnections for cost-effectiveness. In this paper, we propose a new type of interconnection networks called <italic>Exchanged Cube-Connected Cycles (ExCCC)</italic>. The <italic>ExCCC</italic> network is an extension of <italic>Exchanged Hypercube (EH)</italic> network by replacing each node with a cycle. The <italic>EH</italic> network is based on link removal from a <italic>Hypercube</italic> network, which makes the <italic>EH</italic> network more cost-effective as it scales up. After analyzing the topological properties of <italic>ExCCC</italic>, we employ commodity switches to construct a new class of data center network models, namely <italic>ExCCC-DCN</italic>, by leveraging the advantages of the <italic>ExCCC</italic> architecture. The analysis and experimental results demonstrate that the proposed <italic>ExCCC-DCN</italic> models significantly outperform four state-of-the-art data center network models in terms of the total cost, power consumption, scalability, and other static characteristics. It achieves the goals of low cost, low energy consumption, high network throughput, and high scalability simultaneously.
