The rapid growth of network bandwidth at the edge makes it possible to support high bandwidth 8K & volumetric video streaming, Augmented Reality/Virtual Reality and Distributed AI and IoT applications. The growing traffic demands from these new applications will pose enormous burdens on cellular packet core networks and mobile edge clouds, where NFV is meant to be a key enabling technology. The software nature of network function virtualization (NFV) enables network operators to dynamically scale out/in by instantiating more/fewer instances of network functions (NFs) in accordance with traffic demands or in preparation for or reaction to failures, thereby providing high scalability, availability and fault tolerance. Perhaps more importantly, NFV endows network carriers and service providers with the ability to quickly adapt, upgrade or roll out new network features or services. This proposal advances a new "greenfield" framework for refactoring and re-architecting NFV, referred to as NFLambda. The goal is to tackle the challenges in scaling packet processing for service function chaining in commodity multi-core servers to 100 Gbps and beyond. If successful, NFLamda will serve as an enabling technology for creating more cost effective and elastic service environments in emerging 5G and other access networks. The goal of this project is to tackle the challenges in scaling service function chain packet processing in commodity multi-core servers to 100 Gbps and beyond, while at the same time being able to fully take advantage of the software nature of NFV. NFLambda is designed with several salient features using a novel actor framework in the style of functional reactive programming (FRP). The NFLambda actor framework provides a powerful declarative, secure-by-design programming model with built-in monitoring and security mechanisms. The proposal advances a principled approach for decomposing conventional ("monolithic") NFs into a collection of granular actors via separation of control and data, refactoring both states and operations. NFLambda is designed to not only take into account the server architecture and cache/memory access resource constraints, but also effectively leverage software/hardware capabilities (e.g., compilation optimization techniques and hardware accelerators), smart NICs and programmable switches to achieve high performance packet processing. NFLambda is highly scalable, resilient and secure by design. The project will engage undergraduate, women and URM students in integrative research and education and provide outreach to K-12 students. The project will also engage industrial partners for tech transfer.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.

边缘网络带宽的快速增长使得可以支持高带宽8K和体积视频流，增强现实/虚拟现实以及分布式AI和IoT应用程序。 这些新应用程序的流量需求不断增长，将对蜂窝数据包核心网络和移动边缘云造成巨大的负担，其中NFV是一种关键的促成技术。 网络函数虚拟化（NFV）的软件性质使网络运营商可以根据流量需求或为故障做准备或反应，从而使更多/更少的网络函数实例（NFS）实例化/更少，从而提供高可扩展性，可用性，可用性，可用性，可用性。也许更重要的是，NFV赋予网络运营商和服务提供商能够快速调整，升级或推出新的网络功能或服务。 该提案为重构和重新构造的NFV（称为Nflambda）的重构和重新构造的新“ Greenfield”框架发展。目的是应对商品多核服务器中的服务功能链条缩放数据包处理的挑战，至100 Gbps及以后。如果成功的话，NFLAMDA将作为一种促成技术，可以在新兴的5G和其他访问网络中创建更具成本效益和弹性的服务环境。该项目的目的是应对商品多核服务器中扩展服务功能链数据包处理的挑战至100 Gbps及以后，同时也能够充分利用NFV的软件性质。 Nflambda的设计具有多种出色的功能，该功能具有功能性反应性编程（FRP）风格的新型Actor框架。 Nflambda Actor框架提供了一个强大的声明性，安全的按设计编程模型，并具有内置的监视和安全机制。该提案通过分离控制和数据，重构状态和操作，将常规（“单片”）N​​F分解为颗粒状参与者的原则方法。 Nflambda旨在考虑服务器架构和缓存/内存访问资源约束，还有效地利用软件/硬件功能（例如编译优化技术和硬件加速器），智能NICS和可编程交换机来实现高性能数据包处理。 Nflambda高度可扩展，弹性且通过设计安全。该项目将吸引本科生，妇女和URM学生参与综合研究和教育，并向K-12学生提供宣传。该项目还将吸引工业合作伙伴进行技术转移。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响评论标准来评估值得支持的。
