The most fundamental service for the delivery of data on the Internet is routing, the task of computing the path that messages must follow in order to go between networks that are not directly connected. While a large body of work has studied the task of ensuring that these paths are computed correctly, surprisingly little work has been done to study the behavior, when under attack, of the system of computers, software and protocols that compute these paths, what we call the routing system. This project is investigating the resilience of the Internet routing system to attacks that induce "churn" by forcing programs or computers to (temporarily) stop participating in the routing system. The project is devising experiments and simulations that will allow the development of mathematical models that can measure the vulnerability of the routing system to "cascading failures," caused by resource depletion, software faults, and protocol errors, that cause the entire routing system to become unavailable. The project is also developing methods to mitigate the effects of these attacks.The project is expected to result in new data, models, and software that can be used by the community to evaluate and improve the behavior of the current routing system and proposed "future Internet" designs under destabilizing attacks, positively impacting the safety and economic health of the United States and other nations.

在互联网上传输数据的最基本服务是路由，即计算消息在非直接连接的网络之间传输时必须遵循的路径的任务。虽然大量工作已经研究了确保正确计算这些路径的任务，但令人惊讶的是，研究计算这些路径的计算机、软件和协议系统（我们称之为路由系统）在受到攻击时的行为的工作却很少。 该项目正在研究互联网路由系统对通过强制程序或计算机（暂时）停止参与路由系统而引发“搅动”的攻击的恢复能力。 该项目正在设计实验和模拟，以开发数学模型，测量路由系统对“级联故障”的脆弱性，“级联故障”是由资源耗尽、软件故障和协议错误引起的，从而导致整个路由系统变得不可用。 该项目还在开发减轻这些攻击影响的方法。该项目预计将产生新的数据、模型和软件，社区可以使用这些数据、模型和软件来评估和改进当前路由系统的行为，并提出在不稳定攻击下的“未来互联网”设计，从而对美国和其他国家的安全和经济健康产生积极影响。
