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

该项目试图挑战将高速网络链路作为单一逻辑连接点的传统抽象模型。相反，建议的方法将终端主机、网络链路和网络交换矩阵中作为一个整体存在的固有并行性暴露给应用程序和网络控制平面。其结果是网络交换矩阵由多个共存于单个物理拓扑中的不同物理网络组成。通过分离组成网络链路的通道，该项目从根本上重新设计了网络结构，以应对当今的需求和挑战。这项工作的一个关键假设是，与维护传统的胖管道链路抽象相比，组成多个潜在的异质网络提供了更大的可扩展性、性能、服务质量和可管理性。拟议的研究将以四种方式影响更广泛的社区：(1)通过解决支持下一代集群和数据中心的大规模网络基础设施的社会需求，通过(2)与业界接触，以帮助为新设备的设计和构建提供信息，通过(3)通过跨学科研究与其他科学界互动，以及(4)与研究生和本科生接触，将所产生的研究转化为结构化课程和实践学习体验，供传统上代表性不足的学生群体使用。

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.
