EAGER: Bridging The Gap Between Application Architecture and Network Architecture In Cyberphysical Systems Via Named Data Networking

本探索性项目应用命名数据网络（NDN）的设计方法为网络物理系统（CPS）带来好处。NDN是一种新兴的网络架构，它将Internet的瘦腰从IP的以主机为中心的模型转变为以数据为中心的模型。它使用名称直接获取数据，并使用加密签名将名称绑定到数据。该项目使用楼宇自动化系统（BAS）作为CPS的驱动和代表案例，包括供暖、通风和空调（HVAC）、照明、水、物理门禁控制和其他建筑系统的控制、监测和管理。它将评估，在这样的现实世界的楼宇自动化系统中，NDN是否可以提供：(1)量化更好的性能和可靠性特征；(2)等效或更好的设备寻址功能作为典型的中间件和特定于应用程序的协议；(3)降低了应用程序开发的复杂性；(4)通过基本NDN功能和策略进行身份验证、验证和访问控制。该项目还考虑了提供新功能的NDN设备和服务命名方法。为了提供一个环境来构建和评估NDN对BAS的支持，该项目将在NDN测试台上部署一个闭环控制系统，包括工业标准的电力需求监控和照明控制。更广泛的影响：网络物理系统是在关键基础设施中广泛使用计算技术的一个新的和快速发展的前沿。然而，现有的CPS可能很复杂，通常难以构建和维护，易受变化的影响，容易受到导致潜在大影响的故障的影响。这项工作旨在为可靠和安全的CPS的快速发展铺平新的方向，并将CPS与传统IT连接起来，用于能源管理、远程操作、监控和数据挖掘以及新型人机交互等应用。

This exploratory project applies the design approach of Named Data Networking (NDN) to generate benefits for cyberphysical systems (CPS). NDN is an emerging network architecture that shifts the thin waist of the Internet from IP's host-centric model to a data-centric model. It uses names to directly fetch data and binds names to data with cryptographic signatures. The project uses Building Automation Systems (BAS) as a driver and representative case of CPS encompassing the control, monitoring and management of heating, ventilation and air conditioning (HVAC), lighting, water, physical access control and other building systems. It will evaluate whether, in such real-world building automation systems, NDN can provide: (1) quantifiably better performance and reliability characteristics; (2) equivalent or better functionality for device addressing as typical middleware and application-specific protocols; (3) reduced application development complexity; (4) authentication, verification, and access control through fundamental NDN capabilities and strategies. The project also considers NDN device and service naming approaches that provide new functionality. To provide an environment on which to build and evaluate NDN support for BAS, the project will deploy a closed loop control system on the NDN testbed consisting of industry-standard electrical demand monitoring and lighting control. Broader Impact: Cyberphysical systems are a new and rapidly progressing frontier in the broad use of computing technologies for critical infrastructure. However, existing CPS can be complex, often difficult to build and maintain, brittle to changes and vulnerable to faults resulting in potentially large impacts. This effort aims to pave a new direction that enables rapid development of reliable and secure CPS, and to bridge CPS with traditional IT for applications including energy management, remote operation, monitoring and data mining, and new types of human-computer interaction.
