The backbone of IT infrastructure is evolving towards a service-oriented model, in which distributed resources (software services, virtualized hardware infrastructure, data repositories, sensors, and network overlays) can be composed as a customized IT service on demand. In particular, cloud computing infrastructure services manage a shared ``cloud'' of servers as a unified hosting substrate for diverse scientific applications, using various technologies to provision servers and orchestrate their operation. At the same time, high-speed networks increasingly offer dynamic provisioning services at multiple layers. Network-connected clouds offer a general, flexible, and powerful model to scale up computing power for data-intensive science applications running at multiple cloud sites. The software produced in this project offers interfaces and control policies for application-driven orchestration of federated clouds interconnected by advanced networks.The project develops software to link cloud computing clusters to other cyberinfrastructure resources through dynamically provisioned networks. A principal focus is to extend popular cloud infrastructure software with hooks to connect provisioned machine instances running in the cloud to external resources through dynamic circuit networks. The project enables cloud applications to dynamically request compute resources at multiple points in the network, together with bandwidth-provisioned network pipes to interconnect them and link them with other services and data repositories. The orchestration framework is based on the Open Resource Control Architecture (ORCA), an extensible platform for dynamic leasing of resources in a shared networked infrastructure. The resource allocation policies are enabled through semantic resource descriptions and extended intelligent SPARQL queries. Driving applications for this project are MotifNetwork, IMG/JGI and Supernova Factory and sensor networks linked to cloud resources (CASA). Development and demonstrations leverage the Breakable Experimental Network (BEN, a multi-layer optical network testbed located in North Carolina), NLR and ESNet.

IT基础架构的骨干正在发展为面向服务的模型，其中分布式资源（软件服务，虚拟性硬件基础架构，数据存储库，传感器和网络叠加层）可以按需构建为自定义的IT服务。 特别是，云计算基础架构服务管理服务器的共享``云''作为统一的托管基板，用于多种科学应用程序，使用各种技术来提供服务器并协调其操作。 同时，高速网络越来越多地在多层提供动态的配置服务。 网络连接的云提供了一个通用，灵活和强大的模型，可扩展在多个云站点运行的数据密集型科学应用程序的计算能力。该项目中生产的软件提供了通过高级网络互连应用程序驱动的联合云的界面和控制策略。该项目开发软件，通过动态提供的网络将云计算簇与其他网络基础结构资源链接到其他网络基础结构。 主要重点是扩展具有挂钩的流行云基础架构软件，以通过动态电路网络连接云中运行的已提供的机器实例与外部资源。 该项目使云应用程序能够在网络中的多个点动态地请求计算资源，以及带宽提供的网络管道，以互连并将其与其他服务和数据存储库联系起来。 编排框架基于开放资源控制体系结构（ORCA），这是一个可扩展的平台，用于在共享网络基础架构中动态租赁资源。 资源分配策略是通过语义资源描述和扩展智能SPARQL查询启用的。该项目的驾驶应用程序是Motifnetwork，IMG/JGI和Supernova Factory以及链接到云资源（CASA）的传感器网络。开发和演示利用了可损坏的实验网络（BEN，位于北卡罗来纳州的多层光网测试台），NLR和ESNET。
