NeTS: Medium: Improving Network Performance and Efficiency through Multi-Channel Network Links

这个项目试图挑战传统的抽象模型的高速网络链接作为一个单一的，逻辑的连接点。 相反，所提出的方法将存在于终端主机、网络链路和网络结构中的固有并行性作为一个整体暴露给应用程序和网络控制平面。其结果是网络结构由多个不同的物理网络组成，这些网络在单个物理拓扑中共存。通过解耦构成网络链路的通道，该项目从根本上重新设计了网络结构，以满足当今的要求和挑战。这项工作的一个关键假设是，组成多个，潜在的异构网络提供了更大的可扩展性，性能，服务质量，和比保持传统的胖管道链路抽象的可扩展性。拟议的研究将影响更广泛的社区在四个方面：（1）通过满足社会对大规模网络基础设施的需求，以支持下一代集群和数据中心，通过（2）与行业合作，帮助为新设备的设计和制造提供信息，通过（3）通过跨学科研究与其他科学团体互动，以及通过（4）与研究生和本科生合作，将研究成果转化为结构化课程和实践学习经验，为传统上代表性不足的学生群体提供服务。

This project seeks to challenge the conventional abstract model of a high-speed network link as a single, logical point of attachment. Instead, the proposed approach exposes the inherent parallelism that exists within the end host, network links, and the network fabric as a whole, to applications and the network control plane. The result is a network fabric consisting of a number of distinct physical networks that coexist within a single physical topology. By decoupling the channels making up network links, the project radically redesigns the network fabric to address today's requirements and challenges. A key hypothesis of this work is that composing multiple, potentially heterogeneous networks provides for greater scaling, performance, service quality, and manageability than maintaining the legacy fat-pipe link abstraction.The proposed research will impact the broader community in four ways: (1) by addressing the societal need of large-scale networking infrastructure to support next-generation clusters and data centers, by (2) engaging with industry to help inform the design and construction of new devices, by (3) interacting with other scientific communities through interdisciplinary research, and by (4) engaging with graduate and undergraduate students to translate the resulting research into structured courses and hands-on learning experiences for traditionally under-representedstudent groups.
