NeTS: CSR: Medium: Network Functions Virtualization With Timing Guarantees

该项目利用实时系统领域的技术来构建一个可扩展的网络功能虚拟化（NFV）平台，该平台可以在云计算环境中提供延迟和吞吐量保证。实时系统已经成功地为各种设备提供了性能保证，包括安全气囊和起搏器等关键设备，在这些设备上，即使是很小的延迟也必须小心避免；因此，该技术可以为具有可预测性能的NFV平台提供坚实的基础。本研究的智力价值在于：1)开发适合NFV平台的新颖的、可扩展的实时调度技术；2)将弹性和运行时适应性与这些调度技术相结合；3)应用声明性网络和查询规划技术来分析和有效地调度虚拟网络功能；4)开发合适的诊断原语。拟议研究的更广泛影响在于下一代NFV平台的开发，该平台将简化数据中心的网络管理，并支持新兴的性能关键型应用。

This project leverages techniques from the real-time systems domain to construct a scalable Network Function Virtualization (NFV) platform that can provide latency and throughput guarantees in a cloud computing setting. Real-time systems have been successfully providing performance guarantees on a wide range of devices, including critical ones such as airbags and pacemakers, where even small delays must be carefully avoided; hence, this technology canprovide a solid foundation for an NFV platform with predictable performance.The intellectual merit of the proposed research is 1) the development of novel, scalable real-time scheduling techniques suited for NFV platforms, 2) the integration of elasticity and run-time adaptation with these scheduling techniques, 3) the application of declarative networking and query planning techniques to analyze and efficiently schedule virtual network functions, and 4) the development of suitable diagnostic primitives.The broader impact of the proposed research lies in the development of next-generation NFV platformsthat will both simplify network management in data centers and support emerging performance-critical applications.
