The goal of this project is to develop a framework for designing a multipath routing architecture whereby end hosts make adaptive, robust congestion-aware routing decisions based on information provided to them by their ISPs or by an overlay network infrastructure. Multipath routing can be used to perform congestion avoidance and to provide a natural load balancing over the different paths and a robust recovery from a link failure. The project will generate new network architectures that provide robustness to applications and networks in the face of faults and dynamic changes in traffic demands through congestion aware multipath routing. On the theoretical side, the principal investigators (PIs) will develop mathematical models to study the performance, stability, robustness, and economics of a multipath routing architecture. On the practical side, the PIs will develop new algorithms and mechanisms for providing congestion-dependent multipath routing that tolerate failures, onsets of congestion, etc. as well as new algorithms for performing traffic engineering appropriate for networks within which most traffic is multi-path.Broader Impact: The project integrates research and education of graduate and undergraduate students through the close interaction and mentoring of students by project faculty. The PIs will seek international involvement with Universities in Brazil. The latter involvement will include the refinement of existing networked teaching tools so as to make them more robust through application of our multipath techniques.

该项目的目标是开发一个用于设计多路径路由架构的框架，最终主机可以根据 ISP 或覆盖网络基础设施提供给它们的信息，做出自适应、稳健的拥塞感知路由决策。多路径路由可用于执行拥塞避免并在不同路径上提供自然负载平衡以及从链路故障中的稳健恢复。该项目将生成新的网络架构，通过拥塞感知多路径路由，为应用程序和网络提供鲁棒性，以应对故障和流量需求的动态变化。 在理论方面，主要研究人员 (PI) 将开发数学模型来研究多路径路由架构的性能、稳定性、鲁棒性和经济性。在实际方面，PI将开发新的算法和机制，以提供依赖于拥塞的多路径路由，以容忍故障、拥塞的发生等，以及用于执行适合大多数流量为多路径的网络的流量工程的新算法.更广泛的影响：该项目通过项目教师对学生的密切互动和指导，整合了研究生和本科生的研究和教育。 PI 将寻求巴西大学的国际参与。后者的参与将包括改进现有的网络教学工具，以便通过应用我们的多路径技术使它们更加强大。
