In today's Internet, a single service provider rarely has purview over an entire end-to-end path; this situation hinders the deployment and adoption of new network services. The PI propose to design and prototype a new network architecture, Cabo (Concurrent Architectures are Better than One), which resolves this problem by separating infrastructure providers (who own and manage the physical network infrastructure) from service providers (who deploy end-to-end services to users). Using Cabo, service providers will reserve network resources (i.e., virtual nodes and links) on equipment that may span one or more infrastructure providers. The separation of network service providers from infrastructure providers also allows a single service provider to construct end-to-end services; it also allows a service provider to operate multiple virtual networks, each of which is tailored to a specific application. For example, one virtual network may provide strict security guarantees but may not provide complete reachability to all destinations, while another virtual network may guarantee global reachability for applications that do not require strong security guarantees. The outcome of this project will be: (1) the design and implementation of a substrate that service providers can use to deploy new network architectures and services, and (2) investigation of example scenarios where Cabo can provide better security, robustness, and end-to-end performance guarantees. Cabo's initial design leverages virtualization, tunneling, and new experimental platforms for network protocols and architectures, including the PIs' own Virtual Network Infrastructure (VINI), which the PIs plan to use to prototype and evaluate their ideas. Successful completion of this project will have significant impact on Future Internet architecture development and deployment.

在当今的互联网中，单一的服务提供商很少拥有整个端到端路径的权限；这种情况阻碍了新网络服务的部署和采用。PI提出了一种新的网络体系结构CABO(并发体系结构比一种体系结构更好)，它通过将基础设施提供商(拥有和管理物理网络基础设施)与服务提供商(向用户部署端到端服务)分开来解决这一问题。使用CABO，服务提供商将在可能跨越一个或多个基础设施提供商的设备上预留网络资源(即虚拟节点和链路)。网络服务提供商与基础设施提供商的分离还允许单个服务提供商构建端到端服务；它还允许服务提供商运营多个虚拟网络，每个虚拟网络都是为特定应用量身定做的。例如，一个虚拟网络可以提供严格的安全保证，但可能不能提供对所有目的地的完全可达性，而另一个虚拟网络可以保证对不需要强安全保证的应用的全局可达性。该项目的成果将是：(1)设计和实现服务提供商可以用来部署新的网络架构和服务的底层，以及(2)CABO可以提供更好的安全性、健壮性和端到端性能保证的示例场景的调查。CABO的初始设计利用了网络协议和体系结构的虚拟化、隧道和新的实验平台，包括PI自己的虚拟网络基础设施(VINI)，PI计划使用它来制作原型和评估他们的想法。该项目的成功完成将对未来互联网架构的开发和部署产生重大影响。
