One of the primary limiting factors to improving the security, robustness, and performance of the global computation and communication infrastructure is the difficulty of subjecting novel protocols, applications, and services to realistic network conditions, at scale. Recent advancements in emulation technology enable running unmodified applications on stock hardware and operating systems. These applications can be accurately subject to the wide-area communication characteristics of topologies consisting of tens of thousands of routers and 10 Gigabits per second of aggregate bandwidth. Given these advancements, the principal challenge in carrying out realistic large-scale experiments lies in what to emulate rather than how to emulate it. The community currently lacks the ability to: i) generate topologies that reflect important characteristics of the Internet, ii) annotate the topologies with link capacities, latencies, and loss rates, and iii) subject a given topology to realistic levels of background traffic.The goal of this proposal is to develop a unified infrastructure for creating realistic network topologies and to accurately annotate them with appropriate distributions for bandwidths, latencies, and round trip times. Further, it will be possible to subject individual topology links to realistic packet arrival processes. Broader Impact: Taken together, the components of this proposal have the potential to effect a qualitative change in the community's ability to conduct controlled experiments that accurately reflect a variety of both current and future network scenarios. Such ability will then dramatically accelerate the

全球计算和通信基础架构的安全性，鲁棒性和性能的主要因素之一是将新颖的协议，应用和服务对现实网络条件进行大规模进行的困难。 仿真技术的最新进步使在库存硬件和操作系统上运行未修改的应用程序。这些应用可以准确地受到拓扑的广泛通信特征，这些拓扑特征包括数以万计的路由器和10千兆位的总带宽。 鉴于这些进步，进行现实的大规模实验的主要挑战在于效仿什么而不是如何效仿。 当前社区缺乏以下能力：i）产生反映互联网重要特征的拓扑，ii）用链接能力，潜伏期和损失率和iii）注释拓扑，以及iii）对现实的背景流量的给定拓扑。该提案的目标是，该提案的目标是为了创建一个统一的基础结构，以使其与现实的网络拓扑并进行适当的待遇，并将其分配到适当的环境中。 此外，可以将单个拓扑链接到现实的数据包到达过程中。 更广泛的影响：综上所述，该提案的组成部分有可能影响社区进行受控实验的能力，以准确反映出各种当前和未来的网络方案。 然后，这种能力将极大地加速
