Collaborative Research: NETS-NBD: Towards a Multipath Network Architecture for Robust Data Transport

这个项目的目标是开发一个框架，设计一个多路径路由架构，使终端主机作出自适应的，鲁棒的路由感知决策的基础上提供给他们的信息，他们的ISP或覆盖网络基础设施。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的负载平衡和从链路故障中的鲁棒恢复。该项目将产生新的网络架构，通过拥塞感知多路径路由，在面对故障和流量需求动态变化时为应用程序和网络提供鲁棒性。 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。在实践方面，PI将开发新的算法和机制，用于提供依赖于路由的多路径路由，以容忍故障、拥塞等，以及用于执行流量工程的新算法，适用于大多数流量为多路径的网络。该项目通过项目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教师。PI将寻求与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其更加强大。

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.
