Recently, both the networking industry and Internet research communities have shown significant interest in ``Intelligent Routing Control'' (IRC) systems. There are two types of IRC systems: routing overlays and intelligent multihoming. First, IRC systems perform load-sensitive routing, allowing dynamic path changes based on the measured performance of candidate paths. Second, with IRC systems it becomes possible to route different classes of traffic to the same destination through different paths. Third, IRC systems give edge networks the flexibility to choose their path to common destinations.This project investigates IRC systems from a critical perspective, examining both their potential to improve network routing and application performance, but also the risk that such systems may introduce in the Internet in the form of instability and conflicting routing incentives. The project's main research tasks are to: investigate both routing overlays and intelligent multihoming and compare the pros and cons of the two architectures; identify the key issues in the design and operation of IRC systems; design algorithms and mechanisms for the stable and efficient operation of IRC Systems; evaluate the previous results through realistic simulations and wide-scale experiments over Planetlab and other testbeds.The final outcome of this project will be a coherent set of designs and algorithms for IRC systems, considering both performance and stability, and focusing not only on the incentives of individual players but also on the global utility of the Internet as a whole. The project can have a significant impact on the design and deployment of IRC systems. The project's results will be disseminated through research publications, and through direct communication with manufacturers of IRC systems and network operators.

最近，网络工业和因特网研究团体都对"智能路由控制“（IRC）系统表现出极大的兴趣。有两种类型的IRC系统：路由覆盖和智能多宿主。首先，IRC系统执行负载敏感路由，允许基于候选路径的测量性能的动态路径改变。其次，IRC系统可以将不同类别的流量通过不同的路径路由到同一目的地。第三，IRC系统给边缘网络的灵活性，选择他们的路径到共同的destinations.This项目调查IRC系统从一个关键的角度来看，既检查其潜力，以改善网络路由和应用程序的性能，但也有风险，这种系统可能会在互联网中引入的形式不稳定和相互冲突的路由激励。该项目的主要研究任务是：调查路由覆盖和智能多宿主，并比较两种架构的优缺点;确定IRC系统设计和运行中的关键问题;设计IRC系统稳定有效运行的算法和机制;通过真实的模拟和广泛的评估以前的结果，在Planetlab和其他测试平台上进行大规模实验。该项目的最终成果将是一套连贯的IRC系统设计和算法，同时考虑性能和稳定性，不仅关注单个参与者的激励，而且关注整个互联网的全球效用。该项目可能对IRC系统的设计和部署产生重大影响。该项目的成果将通过研究出版物以及通过与IRC系统制造商和网络运营商的直接沟通传播。
