ITR-(NHS)-(sim): Large-Scale Network Simulation for Security and Survivability Evaluation

提案编号：CNS-0427700标题：ITR -用于安全性和可生存性评估的大规模网络模拟首席研究员：乔治F. Internet路由基础设施和域名基础设施是巨大的、高度动态的系统。 理解和预测这些系统的功能和行为是非常复杂的。 在许多情况下，复杂系统的详细建模和仿真可以帮助理解它们的行为，无论是在预测模式还是在反应环境中。 通过这种系统的高质量仿真模型，可以预测拟议变更的效果，并可以了解先前故障的原因。 此外，在不影响已部署系统的情况下，可以在模拟环境中对破坏性行为进行建模。本研究使用新开发的能够对由数十万或数百万个网络元素组成的网络进行建模的高性能仿真工具，对这些系统的行为进行详细的研究和分析。 工作的很大一部分将侧重于分析这些关键的因特网基础设施服务在出现故意或意外故障或错误配置时的生存能力。 如果这项工作取得成功，互联网将变得更有弹性的故障和更可靠的最终用户。

Proposal Number: CNS-0427700Title: ITR - Large-Scale Network Simulation for Security and Survivability EvaluationPrincipal Investigator: George F. RileyThe Internet routing infrastructure and domain name infrastructure are huge and highly dynamic systems. Understanding and predicting the functionality and behavior of these systems is highly complex. As is true in many cases, detailed modeling and simulation of complex systems can help in understanding their behavior, both in a predictive mode and in a reactive environment. With a high quality simulation model of such a system, one can predict the effect of proposed changes, and can understand causes of prior failures. Further, one can model disruptive actions in the simulated environment without affecting deployed systems.This research is focused on the detailed study and analysis of the behavior of these systems, using newly developed high-performance simulation tools capable of modeling networks consisting of hundreds of thousands or millions of network elements. A large part of the effort will be focused on survivability analysis for these critical Internet infrastructure services, in the presence of either deliberate or accidental failures or mis-configurations. If this work succeds, the Internet will become more resilient to failures and more dependable for end users.
