Collaborative Research: Systems of Networked Embedded Devices

该奖项设立了一项为期一年的NSF计划拨款，作为NSF/CISE清洁互联网重塑计划（CIRI）的一部分，旨在制定下一代互联网的研究议程。互联网影响了社会的方方面面：它从根本上改变了企业、政府和普通公民接受、管理和提供服务的方式。然而，在最初的“尽力而为”互联网协议的设计与实时控制系统领域的需求之间存在根本的不匹配。由于目前大多数实时网络都是隔离的，因此已经开发了各种不同的、很大程度上不兼容的实时网络协议，并将其标准化，以便在各种应用领域中采用。例如：用于工业过程控制的现场总线，用于航空的ARINC，以及用于汽车应用的CAN和FlexRay。然而，越来越多的安全关键应用，如医疗系统，关键基础设施，如电网和制造业，以及汽车和航空系统依赖于网络互操作。这一规划活动将把实时嵌入式系统和网络社区聚集在一起，重新思考如何提供连贯的“实时互联网”服务，并为未来的实时互联网能力建立需求、方法和研究需求。

This award establishes a 1-year NSF planning grant as part of the NSF/CISE Clean-slate Internet Reinvention Initiative (CIRI), which aims to develop the research agenda for a next-generation Internet. The Internet has impacted all aspects of society: it has fundamentally changed the manner in which corporations, governments, and ordinary citizens receive, manage, and deliver services. However, there is a fundamental mismatch between the design of the original "best-effort" Internet protocols and the requirements of the real-time control system domain. Since the majority of real-time networks currently are isolated, a variety of disparate and largely incompatible real-time network protocols have been developed and standardized for industry adoption in various application domains. Examples are: FieldBus for industrial process control, ARINC for aviation, and CAN and FlexRay in automotive applications. However, increasingly, safety-critical applications such as medical systems, critical infrastructures such as the power grid and, manufacturing, and automotive and aviation systems depend on networked interoperation. This planning activity will bring together the real time embedded systems and networking communities to rethink how coherent "real time Internet" services could be provided and to establish requirements, approaches, and research needs for future real-time Internet capability.
