CCRI: Planning-C: TopoCloud: A New Community Testbed With Unique Network Topology Flexibility

该项目的重点是与TopoCloud相关的社区形成和规划活动，TopoCloud是一个新的网络实验测试平台。与早期的网络测试平台相比，TopoCloud将使实验者能够查看和修改数据中心网络的拓扑结构，即其组件互连的方式。为了向实验者提供对可编程网络设备的专有、低级别访问，TopoCloud中所有用户控制的网络设备都将连接到操作员控制的网络。该网络将用于动态地“重新布线”服务器和设备，以物理方式创建保证全速运行的专用网络。云和云服务中心提供的服务是在线世界的核心，支持网站，应用程序甚至医疗设备。这些数据中心内部的网络是数据中心性能、健壮性和成本的关键决定因素。TopoCloud将是一个独特的资源，可以对数据中心网络的构建和管理方式进行变革性研究。因此，该奖项旨在促进研究，以提高网络的性能并降低成本，而网络是人们日常生活中使用的许多服务的基础。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project is focused on community formation and planning activities related to TopoCloud, a new testbed for network experimentation. Compared to earlier network testbeds, TopoCloud will give experimenters the ability to see and modify a datacenter network's topology -- that is, the way in which its components are interconnected. To provide experimenters with exclusive, low-level access to programmable networking devices, all user-controlled networking devices in TopoCloud will be connected to an operator-controlled network. This network will be used to dynamically “rewire” servers and devices to physically create private networks that are guaranteed to run at full speed.Services provided by clouds and datacenters are at the core of much of the online world, supporting websites, apps, and even medical devices. The networks inside of these datacenters are critical determinants of the datacenter's performance, robustness, and cost. TopoCloud will be a unique resource that enables transformative research on the ways that datacenter networks are built and managed. As a result, it aims to enable research that will improve performance and lower costs in the networks that form the foundation for many of the services used in people’s daily lives.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.
