CRII: CNS: A Hybrid Software Defined Networking-Information Centric Networking Framework for the Reuse of Computation at the Network Edge

增强现实和物联网(IoT)等下一代应用的采用预计将在未来几年快速增长。到2025年，物联网设备数量预计将达到750亿台，而潜在使用案例(例如，拥有数十万或数百万居民的智能城市)的规模预计也将增长。在这种用例中，用户可以请求物理上接近他们的服务器处理具有时间、空间或语义相似性的数据。对非常相似的数据的重复处理可能导致相同的处理输出，并因此执行重复(冗余)计算。该项目促进了我们对“计算重复使用”概念的理解，即在对类似数据的处理请求之间重复使用/共享处理输出，有可能：(1)减少处理类似数据的时间，从而减少下一代应用程序所感知的总等待时间；(2)消除执行冗余计算，从而有效地利用可用的计算资源。我们的项目将产生一个新的网络框架，以便识别处理类似数据的请求并将其转发到相同的服务器，从而促进在现实的基础设施部署中重复使用计算。该项目的研究成果将被纳入大学课程，同时该项目还将提供机会，扩大STEM的参与度和多样性。该项目旨在促进边缘计算体系结构的最新发展，以便通过基于信息中心网络(ICN)/命名数据网络(NDN)和软件定义网络(SDN)的新型混合网络框架促进计算的重复使用。该框架充分利用了ICN/NDN和SDN的优点，通过：(I)具有语义意义的ICN/NDN命名和状态转发平面，用于向可以重用类似先前执行的任务的边缘服务器无缝和自适应地转发任务；(Ii)转发平面和控制平面的分离以及用于协调计算重用语义的可编程(逻辑)集中式SDN智能，从而实现了以服务为中心的、计算重用感知的和“软件化”的体系结构。这个项目将解决在现实边缘计算环境中实现计算重用的网络系统设计和开发中的基本挑战，其中多个边缘服务器可能可用于冗余、容错和负载平衡目的，促进普及边缘计算部署。该项目由网络技术和系统(NETS)计划和既定的激励竞争研究计划(EPSCoR)联合资助。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。

The adoption of next-generation applications, such as Augmented Reality and Internet-of-Things (IoT), is expected to grow rapidly in the years to come. The number of IoT devices is expected to reach 75 billion by 2025, while the scale of potential use-cases (e.g., smart cities with hundreds of thousands or millions of residents) is also expected to grow. In such use-cases, users may request the processing of data with temporal, spatial, or semantic similarity by servers physically close to them. The repeated processing of considerably similar data may result in the same processing outputs and thus the execution of duplicate (redundant) computation. This project advances our understanding of the notion of “computation reuse”, where the processing outputs are reused/shared among processing requests for similar data, having the potential to: (i) reduce the time for the processing of similar data and thus the overall latency perceived by next-generation applications; and (ii) eliminate the execution of redundant computation, so that the available computing resources are effectively utilized. Our project will result in a novel network framework, so that requests for the processing of similar data are identified and forwarded to the same servers, facilitating the reuse of computation in realistic infrastructure deployments. The research outcomes of this project will be incorporated into university course curriculum, while this project will also offer opportunities that broaden participation and diversity in STEM.This project aims to advance the state-of-the art in edge computing architectures in order to facilitate the reuse of computation through a novel, hybrid network framework based on Information-Centric Networking (ICN)/Named-Data Networking (NDN) and Software-Defined Networking (SDN). The proposed framework capitalizes on the best of both ICN/NDN and SDN to realize a service-centric, computation reuse-aware, and “softwarized” architecture through: (i) the semantically meaningful ICN/NDN naming and stateful forwarding plane for the seamless and adaptive task forwarding towards edge servers that can reuse similar previously executed tasks; and (ii) the separation of forwarding and control planes and the programmable (logically) centralized SDN intelligence for the orchestration of the computation reuse semantics. This project will tackle fundamental challenges in the design and development of network systems for the realization of computation reuse in realistic edge computing environments, where multiple edge servers may be available for redundancy, fault tolerance, and load balancing purposes, facilitating the pervasive edge computing deployment.This project is jointly funded by Networking Technology and Systems(NeTS)program and the Established Program to Stimulate Competitive Research (EPSCoR).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.
