FIND: Distributed Application Management Service (DAMS)

CNS？0828923Bman，Kenneth Cornell University FIND：分布式应用程序管理服务(DAMS)自诞生以来，Internet对于支持提供安全性、可靠性或其他信任属性的应用程序来说一直是一个困难的环境。然而，我们看到了一波网络应用程序，它们需要维护私人数据(例如，敏感的医疗记录)或扮演正确、容错行为至关重要的角色(例如，空中交通管制)。每个开发人员都被迫发明自己的解决方案，以弥补现有互联网的局限性。这项研究的中心前提是，这代表着一种危险的趋势，研究界必须尽其所能创造新的更好的选择。智力上的好处：康奈尔大学的研究人员将开发旨在支持互联网上一种新型值得信赖的分布式计算服务的技术。该项目将产生基础性的智力影响，展示以前被视为十几个单独的、往往定义不清的函数可以统一到单个概念上优雅的抽象(分布式角色委派)中，并通过发展所需的科学和数学来推理这一机制。该项目旨在帮助创建下一代任务关键型网络应用程序？可以被赋予敏感角色的系统，因为它们包含了被证明具有所需属性的解决方案广泛影响：该项目旨在通过创建功能强大、可扩展的技术来创建当今全球开发人员所缺乏的有用的解决方案，该技术将实现理论上最佳的性能和可扩展性，与特定于应用程序的一致性要求施加的限制保持一致。

CNS ? 0828923Birman, Kenneth Cornell UniversityFIND: Distributed Application Management Service (DAMS)Since its inception, the Internet has been a difficult environment for supporting applications offering security, reliability, or other trust properties. Yet we?re seeing a wave of network applications that need to maintain private data (for example, sensitive medical records) or play roles in which correct, fault-tolerant behavior is critical (for example, air traffic control). Each developer has been forced to invent his or her own workarounds to compensate for the limitations of the existing Internet. The central premise of this research is that this represents a dangerous trend and that the research community must do what it can to create new and better options.Intellectual Merit: Cornell University researchers will develop technologies aimed at supporting a new kind of trustworthy distributed computing service on the Internet. The project will have a foundational intellectual impact by showing that what have previously been treated as a dozen separate, often ill-defined functions can be unified into a single conceptually elegant abstraction (distributed role delegation), and by developing the needed science and mathematics to reason about this mechanism. This project aims to help create the next generation of mission-critical networked applications ? systems that can be entrusted with sensitive roles, because they embody solutions shown to have the needed propertiesBroader Impact: This project seeks to create a useful solution that developers worldwide today lack by creating a powerful, extensible technology that will achieve theoretically optimal performance and scalability, consistent with the constraints imposed by application-specific consistency requirements.
