There is an ever-increasing demand for cloud computing services, and large-scale datacenters are constantly evolving to meet this demand. As the need for data and data analytics grows, providers are turning to geo-distributed datacenters to provide customers very low latency access to information and computational capability. This results in high capacity, highly-varying inter-datacenter network traffic that must be reliably and cost-effectively accommodated by fiber optic networks. Recent advances in agile and flexible optical networking have made Flexible Optical Networks (FONs) a promising candidate for meeting these dynamic and heterogeneous connection demands. The goal of this project is to develop network design and provisioning strategies for inter-datacenter FONs that can support a wide range of data traffic flow. To address the continued exponential growth in network capacity, the project includes consideration of a novel, flexible, cost-effective optical technology, which introduces a way of bundling large traffic demands together as they get routed through the network. The results of the project will inject leading-edge research into education, and enable more efficient and cost-effective distribution of information between datacenters.The research project addresses challenging problems in the design and operation of multigranular flexible optical networks. The challenges demand the development of new strategies to maximize the utilization of precious network resources. Novel algorithms for network design and resource provisioning will be developed, and will be accompanied by sophisticated mathematical models and bound analysis for performance quantification. The specific research objectives of this project are to: 1. Explore the multigranular FONs design space and evaluate performance and complexity trade-offs, balancing performance against complexity or cost.2. Design algorithms for provisioning bandwidth requests in multigranular FONs.3. Design scalable and flexible algorithms on provisioning virtual network (VN) requests by jointly allocating compute and communication resources in inter-datacenter networks.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

对云计算服务的需求不断增加，大规模的数据中心正在不断发展以满足这一需求。随着对数据和数据分析的需求的增长，提供商正在转向地理分布的数据中心，以使客户对信息和计算能力的延迟访问非常低。这会导致高容量，高度变化的跨性别网络流量，必须由光纤网络可靠地可靠地容纳。 敏捷和灵活的光学网络的最新进展使灵活的光网络（FONS）成为满足这些动态和异质连接需求的有前途的候选人。该项目的目的是针对可以支持广泛的数据流量的数据室内FON制定网络设计和供应策略。为了解决网络容量的持续指数增长，该项目包括考虑一种新颖，灵活，具有成本效益的光学技术，该技术引入了一种将大型交通捆绑在一起的方式，因为它们可以通过网络进行路由。 该项目的结果将向教育注入领先的研究，并在数据中心之间对信息进行更有效和成本效益的分配。该研究项目解决了多毛线灵活光学网络的设计和操作中的挑战性问题。挑战需要制定新策略，以最大程度地利用宝贵的网络资源。将开发用于网络设计和资源提供的新型算法，并将伴随复杂的数学模型和界限分析以进行性能量化。该项目的具体研究目标是：1。探索多元FON的设计空间，并评估性能和复杂性权衡，平衡性能与复杂性或成本。2。设计算法，用于在多氏fons中提供带宽请求。3。通过共同分配了跨语境网络中的计算和沟通资源来设计有关配置虚拟网络（VN）请求的可扩展和灵活算法。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来获得支持的。
