This project, evolving the Internet to address new threats, accommodating emerging applications and technologies, and fostering the spread of the network throughout the physical world, aims at developing a Virtualized Network Infrastructure (ViNI) responding to the many challenges faced by today's Internet. In 25 years, the Internet has moved from an obscure research facility, to a critical piece of the national communication infrastructure. To appreciate the significance of this transformation, recall that a bug in the Internet' core routing algorithm inconvenienced several thousands in 1989 and the SQL slammer attack in 2003 grounded commercial airline flights, brought down thousands of ATM machines, and caused damages of approximately $1 billion dollars. As our dependence on the Internet grows, so do both risks and opportunities. Hence, it is imperative that we address new threats, accommodate emerging applications and technologies, and foster the spread of the network throughout the physical work, precisely the goals addressed by this work. The instrument must meet the following requirements. ViNI must-Provide realism through an experimental environment that reflects closely real-world conditions. -Experiments must have access to realistic network topologies, high-speed forwaring engines, real users, and high volumes of real traffic, and dedicated link bandwidth and node resources (CPU, memory, disk) allocated on relatively small time scales.-Give experimenters control over their experiments by making it possible to replicate specific conditions for study. Researchers need tools to easily specify and start experiments, and to inject network events (e.g., failures, packet loss) in a predictable fashion.-Be shared among multiple simultaneous experiments running on the same hardware. PlanetLab, the starting point of ViNI, supports multiple simultaneous experiments by running each in a virtual machine and its virtualization needs to be extended to support the goals and requirements of ViNI. Moreover, new resources, such as IP address blocks, must be globally managed.Hence, to address the challenges that face the Internet today, this experimental infrastructure must reconcile these non-orthogonal requirements to maximize the value of the enabled networking research. ViNI is envisioned serving as a microcosm for the next generation Internet.

该项目旨在发展互联网以应对新的威胁，适应新兴的应用程序和技术，并促进网络在整个物理世界的传播，旨在开发一个虚拟化网络基础设施（ViNI），以应对当今互联网面临的许多挑战。在25年的时间里，互联网已经从一个不起眼的研究设施发展成为国家通信基础设施的关键部分。为了理解这种转变的重要性，请回忆一下1989年互联网核心路由算法中的一个错误导致数千人受伤，2003年的SQL Slammer攻击导致商业航空公司航班停飞，数千台ATM机瘫痪，造成约10亿美元的损失。随着我们对互联网的依赖越来越大，风险和机遇也在增加。因此，我们必须应对新的威胁，适应新兴的应用和技术，并促进网络在整个物理工作中的传播，这正是这项工作所要达到的目标。仪器必须符合以下要求。ViNI必须通过一个能反映真实世界条件的实验环境来提供真实感。- 实验必须能够访问真实的网络拓扑、高速转发引擎、真实的用户和大量的真实的流量，以及在相对较小的时间尺度上分配的专用链路带宽和节点资源（CPU、内存、磁盘）。让实验者通过复制特定的研究条件来控制他们的实验。研究人员需要工具来轻松指定和启动实验，并注入网络事件（例如，失败，数据包丢失）以可预测的方式。在同一硬件上运行的多个同时实验之间共享。PlanetLab是ViNI的起点，通过在虚拟机中运行每个实验来支持多个同时进行的实验，并且其虚拟化需要扩展以支持ViNI的目标和要求。此外，新的资源，如IP地址块，必须在全球范围内进行管理，因此，为了应对当今互联网所面临的挑战，这种实验性的基础设施必须协调这些非正交的要求，以最大限度地提高启用网络研究的价值。ViNI被设想为下一代互联网的缩影。
