Disruptions occur often even in well-managed wired networks due to various failures and more so in emerging wireless networks due to additional causes such as external interference. With the increased use of the Internet for many real-time business applications, there is a growing demand for high service availability despite such disruptions. The goal of this project is to develop resilient routing schemes that mitigate the impact of disruptions on mission-critical applications and services. Specifically, this project aims to: (i) devise a failure inferencing based fast rerouting scheme to provide failure protection similar to MPLS fast-reroute without altering the destination-based forwarding paradigm prevalent in IP networks; (ii) design scalable localized on-demand link state routing schemes that ensure reliable delivery in spite of disruptions without requiring accurate state at each node; (iii) explore ways to utilize both topology and position information for handling disruptions; (iv) extend and apply these methods for load balancing and resilient multicasting. This project will boost the robustness of the Internet and enable services that improve the lives of everyone. It also has significant educational value in addition to facilitating knowledge sharing and distance education as a result of an always-available Internet. The results from this project will be assimilated into advanced graduate level and introductory undergraduate level theory courses as well as hands-on laboratory courses. Furthermore, the research advances will also be disseminated to the industry and the broader community through several publications and prototypes.

即使在管理良好的有线网络中，由于各种故障，也经常会发生中断，而在新兴的无线网络中，由于外部干扰等其他原因，更是如此。 随着许多实时业务应用程序越来越多地使用互联网，尽管存在这种中断，但对高服务可用性的需求也不断增长。该项目的目标是开发弹性路由方案，以减轻中断对关键任务应用程序和服务的影响。 具体来说，该项目旨在：（i）设计一种基于故障推断的快速重路由方案，以提供类似于 MPLS 快速重路由的故障保护，而不改变 IP 网络中普遍存在的基于目的地的转发范例； (ii) 设计可扩展的本地化按需链路状态路由方案，确保在发生中断时仍能可靠地传送，而不需要每个节点的准确状态； (iii) 探索利用拓扑和位置信息来处理中断的方法； (iv)扩展并应用这些方法以实现负载平衡和弹性多播。 该项目将增强互联网的稳健性，并提供改善每个人生活的服务。 由于始终可用的互联网，除了促进知识共享和远程教育之外，它还具有重要的教育价值。 该项目的成果将被纳入高级研究生水平和本科水平入门理论课程以及实践实验室课程。 此外，研究进展还将通过多种出版物和原型传播给行业和更广泛的社区。
