Collaborative Research: CNS Core: Medium: FROOT: Future-Proof, Trustworthy Telemetry on Heterogeneous Networks

随着互联网的发展及其在支持美国经济、商业、医疗、教育和其他服务方面的重要性，确保其基础网络的高性能和高可用性至关重要。这样的网络越来越多地包括一组不同的网络交换机和其他设备，必须以协调的方式进行监视和控制。新兴的网络应用，如云游戏或云流增强现实，预计将通过要求对流量工作负载的快速变化做出实时响应，进一步给控制系统和网络监控带来压力。该项目旨在通过启用网络遥测基础设施来满足未来网络控制的需求，该网络遥测基础设施可以提供有关网络中正在进行的活动的及时、准确和可信的信息。该项目提出了FROOT，这是一种面向未来的、值得信赖的遥测基础设施，适用于各种不同的可编程设备(例如可编程交换机、SmartNIC、CPU和DPU)的网络。该项目采用跨越算法、系统和安全的跨学科方法，通过以下方式为下一代遥测系统的设计和实施提供信息：(1)针对当前和新的测量任务和网络设备的通用基于草图的算法设计和实现；(2)用于处理网络动态的新颖的网络范围的资源优化；以及(3)可靠的草图部署到不同的设备中，以获得关键的遥测信息。研究人员还计划将他们的网络遥测系统部署在大规模开放云试验床上，这是一个由波士顿大学和马萨诸塞州其他机构牵头的开放公共云项目。该项目将导致开发开源工具、算法和原型实现，以减少在真实场景中部署基于草图的遥测的时间。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

With the growth of the Internet and its importance in supporting the US economy, business, health, education and other services, it is critical to ensure both high performance and high availability of the networks underlying it. Increasingly, such networks include a heterogeneous set of network switches and other devices which must be monitored and controlled in a coordinated manner. Emerging networked applications, such as cloud gaming or cloud streamed augmented reality, are expected to further stress both control systems and network monitoring by requiring real-time response to rapid changes in traffic workloads. This project aims to address the needs of future network control by enabling a network telemetry infrastructure that can provide timely, accurate, and trusted information about ongoing activities in the networkThis project proposes FROOT, a future-proof, trustworthy telemetry infrastructure for networks of heterogeneous programmable devices (e.g., programmable switch, SmartNIC, CPU, and DPU). The project takes an interdisciplinary approach spanning algorithms, systems, and security to inform the design and implementation of next generation telemetry systems through the following: (1) universal sketch-based algorithmic design and implementation for current and new measurement tasks and network devices; (2) novel network-wide resource optimization for handling network dynamics; and (3) trustworthy sketch deployment into heterogeneous devices to obtain critical telemetry information. The researchers also plan to deploy their network telemetry system at Mass Open Cloud testbed, an open public cloud project led by Boston University and other institutions in Massachusetts. The project will result in the development of open-source tools, algorithms, and prototype implementations that will reduce the time to deploy sketch-based telemetry in real-world scenarios.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
