This project will conduct exploratory research combining the strengths of two different visions of a next-generation trustworthy Internet: (1) MobilityFirst, a design significantly enhancing mobile and wireless Internet capabilities; and (2) eXpressive Internet Architecture (XIA), a design significantly enhancing evolvability or the ability to introduce new network capabilities. This project will explore a new communication primitive called named asynchronous communication as a proof-of-concept synthesis of XIA and MobilityFirst's strengths with two powerful distinguishing capabilities compared to the current TCP/IP Internet: (1) Asynchronous communication allows two endpoints to exchange data even when network connectivity is flaky and/or when there is minimal or no trusted infrastructure (like cellular, WiFi, or satellite), scenarios in the current Internet works poorly; (2) Named communication enables all communication to be based on human-friendly names as opposed to IP addresses in the current Internet, which simplifies the design, implementation, and maintenance of mobile Internet applications. This EAGER project is the first example of a synthesis effort across two large but separate projects funded as part of NSF's Future Internet Architecture (FIA) program.The technical scope of the project will formalize name-based asynchronous communication as a general-purpose communication primitive that works gracefully even in the absence of contemporaneous end-to-end connectivity between communicating endpoints. Compared to a large body of prior research on disruption-tolerant networks that also shares overlapping goals but has largely focused on mobile ad-hoc edge networks and "bundle" routing protocols, this project will develop an information-centric communication primitive for general-purpose communication across both edge and core networks in a manner that is robust to intermittent connectivity outages. Named asynchronous communication will enable application fine-grained control over the duration for which the network will attempt to complete the retrieval or delivery by leveraging virtualized network functions for intermediate storage. The key enablers of this design are MobilityFirst's global name service (GNS) that enables seamless mobility and endpoint state maintenance in a scalable and secure manner and XIA's ability to retrieve arbitrarily named content in a verifiable manner. This exploratory effort will conduct early research to instantiate a proof-of-concept of named asynchronous communication, identify preliminary use cases, and quantify its benefits and costs in challenged network environments.The broader impact of this exploratory effort is that it helps take us closer towards a trustworthy and powerful Internet, a critical societal and national interest and need. Asynchronous communication in particular is also especially suited to military scenarios and if successfully deployed can significantly improve our national defense capabilities.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.

该项目将结合下一代可信赖互联网的两种不同愿景的优势进行探索性研究：（1）MobilityFirst，一种显着增强移动和无线互联网功能的设计； (2) 表现性互联网架构 (XIA)，一种显着增强可演进性或引入新网络功能的能力的设计。该项目将探索一种称为异步通信的新通信原语，作为 XIA 和 MobilityFirst 优势的概念验证综合，与当前的 TCP/IP 互联网相比，具有两个强大的区别功能：(1) 异步通信允许两个端点交换数据即使网络连接不稳定和/或可信基础设施最少或没有（例如蜂窝、WiFi 或卫星），当前互联网中的场景也效果不佳； (2) 命名通信使得所有通信都基于人类友好的名称，而不是当前互联网中的IP地址，从而简化了移动互联网应用的设计、实现和维护。这个 EAGER 项目是作为 NSF 未来互联网架构 (FIA) 计划一部分资助的两个大型但独立项目的综合工作的第一个例子。该项目的技术范围将把基于名称的异步通信形式化为通用通信原语即使通信端点之间没有同时的端到端连接，它也能正常工作。与之前关于容错网络的大量研究相比，这些研究也有重叠的目标，但主要集中在移动自组织边缘网络和“捆绑”路由协议，该项目将开发一种用于通用目的的以信息为中心的通信原语以对间歇性连接中断具有鲁棒性的方式跨边缘和核心网络进行通信。命名异步通信将使应用程序能够对网络尝试通过利用虚拟化网络功能进行中间存储来完成检索或传送的持续时间进行细粒度控制。此设计的关键推动因素是 MobilityFirst 的全局名称服务 (GNS)，它以可扩展且安全的方式实现无缝移动性和端点状态维护，以及 XIA 以可验证的方式检索任意命名内容的能力。这项探索性工作将进行早期研究，以实例化命名异步通信的概念验证，确定初步用例，并量化其在充满挑战的网络环境中的收益和成本。这项探索性工作的更广泛影响是，它有助于让我们更接近目标建立一个值得信赖和强大的互联网，这是一项重要的社会和国家利益和需求。特别是异步通信也特别适合军事场景，如果成功部署可以显着提高我们的国防能力。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
