Huge data centers increasingly form the heart of the Internet. This project will develop an optical-fiber-based network architecture for data centers, together with associated network control algorithms, that is highly configurable, scalable, and meets the requirements of future data centers. The proposed architecture is hierarchical and uses low-cost passive optics at the lowest levels of the hierarchy, and a combination of electronic and configurable optical switching at higher layers, thus striking a balance between cost and capability of optical systems and devices. Moreover, the use of passive optics significantly reduces energy consumption, which has become an important consideration in large data centers. Our research plan includes both architecture development and algorithm design, including:1. Develop a Wave-Division-Multiplexing (WDM)-based DCN architecture that is low-cost, scalable, and configurable, for meeting the communication requirements of future data centers.2. Develop dynamic reconfiguration algorithms for changing the network topology in response to changes in traffic conditions, in order to reduce the communication load on the network.3. Investigate the use of passive optics in order to reduce energy consumption, and compare different architectural alternatives in terms of energy consumption.The proposed architecture has the potential to dramatically change the way that DCNs are designed, significantly improving their scalability, robustness and energy efficiency. In addition, this investigation will include: (1) dissemination of the results through journal and conference publications to advance the field; (2) incorporation of new theory and algorithms developed through this work into advanced graduate classes; (3) development of experimental projects for undergraduate students; (4) technology transfer to industry (including potential early adoption by an industry partner) and (5) training of graduate and undergraduate students.

庞大的数据中心越来越多地构成了互联网的核心。 该项目将为数据中心开发基于光纤的网络体系结构，以及相关的网络控制算法，该算法高度可配置，可扩展，并满足未来数据中心的要求。所提出的体系结构是分层的，并在层次结构的最低级别上使用低成本的无源光学器件，以及在较高层上电子和可配置的光学切换的组合，从而达到了光学系统和设备的成本和能力之间的平衡。此外，被动光学的使用大大降低了能源消耗，这已成为大型数据中心的重要考虑因素。我们的研究计划包括建筑开发和算法设计，包括：1。开发低成本，可扩展性和可配置的基于Wave-Division-Multiplex（WDM）的DCN体系结构，以满足未来数据中心的通信要求2。开发动态重新配置算法，以响应流量变化而更改网络拓扑，以减少网络上的通信负载3。调查使用被动光学以减少能源消耗的使用，并在能源消耗方面进行比较不同的建筑替代方案。拟议的建筑有可能显着改变DCN设计的方式，从而显着提高其可扩展性，鲁棒性和能源效率。此外，该调查将包括：（1）通过期刊和会议出版物传播结果以推进该领域； （2）通过这项工作开发的新理论和算法的纳入高级研究生班； （3）为本科生开发实验项目； （4）技术转移到行业（包括行业伙伴的潜在提前采用）和（5）培训研究生和本科生。
